FLORENCIO DE LA SIERRA .................... UN POETA DE ESTIRPE AYAVAQUINA.- EN SU POEMARIO : CAPULLOS DE ROCÍO............... AURORA

Hola amigos: A VUELO DE UN QUINDE EL BLOG., continuando con la publicación de los poemas del gran aedo, juglar y vate de estirpe ayavaquina FLORENCIO DE LA SIERRA, cuyo nombre de pila fue: FLORENTINO GÁLVEZ SAAVEDRA, que tenemos en nuestras manos el segundo  libro cuyo título  es : CAPULLOS DE ROCÍO, que fue publicado el 30 de mayo de 1,959, en los Talleres Gráficos de la Compañía de Impresiones y Publicidad S.A., en Lima, Perú;  tal como lo hicimos con los otros poemarios, daremos la misma cabida para ir descifrando poema por poema, y una vez suplico de rodillas a los grandes literatos o comentaristas; disculpar los errores que cometa al interpretar lo que quiso decir el poeta en cada una de sus inspiraciones, soy un entusiasta, que me considero feliz con hacer estas interpretaciones de lo que considero como el más grande poeta que hay producido: AYABACA.

Firmaba todos sus poemas con el seudónimo de "Florencio de la Sierra", pero en realidad era el profesor FLORENTINO GALVEZ SAAVEDRA, nacido el 14-03-1903, Publicó entre otros libros de poesía: “Aúllan los perros” (1951) con portada del artista plástico Essquerriloff, “Capullos de Rocío” (1959) con portada de César Calvo de Araujo, y “La Danza de las Serpientes” (1963) con portada de Raúl Vizcarra. Murió en Lima;  el 17 de noviembre 1964. Su existencia real fue después de 61 años vividos en su tierra natal, Lima, Piura, Bolivia y Chile. Foto: Cedida por Rosa Hortencia Morocho Sánchez.

Tal vez, no es ético mencionarlo; sin embargo, es un  venturoso orgullo que embarga a mi persona, ser un sobrino del poeta; pero como no tengo alternativa trato de explicar; Florencio de la Sierra, fue hermano de madre de mi padre Don José María Sánchez Saavedra; es decir tuvieron ambos la misma madre: Doña Esther Saavedra Guerrero, perteneciente a una familia muy arraigada en la Ciudad de Ayabaca.
Hago la promesa de ser imparcial en los comentarios de cada poema, al mismo tiempo, lo reitero y ruego un perdón por mis errores  a los literatos que alguna vez por casualidad ojeen este Blog: A vuelo de un quinde; por ser un aprendiz  de descifrador de poemas.

Aquí en la imagen observamos la portada  del libro de Poemas: Capullos de Rocío; publicado en Lima el 30 de mayo del 1,959, por la Revista Ediciones Folklore, por el poeta Florentino Gálvez Saavedra; más conocido con el seudónimo : Florencio de la Sierra.

La acuarela de este libro
la dedico a mi hija Esther, cuya presencia
humana y sencilla, es tan igual a la ternura
de mi madre, aquella sombra que desde la
eternidad de la ausencia, está cerca del
trajín de mis días, salpicados de alegría
y silencios.

SEXTO POEMA

Aurora

COMO el guardián de una estrella
que de las nubes se desprende,
corriendo inundas a la tierra
con la última noticia del cielo.

Es así, como el viento para pascua
de las aves, los ríos y los árboles,
en la pupila azul de los horizontes,
proyecta el amanecer de tu sonrisa.

Las ingenuas avecillas
que de los nidos madrugan,
celebran la gracia pastoril
de tu hermosa y gentil llegada.

El rocío que de la ventisca
en silencio al paisaje asoma,
se anida en el núbil follaje
de la neblina y la quebrada.

Así, viene tu imagen del cielo,
pero qué sencilla a la montaña,
el afán de tu sombra se queda
en la brisa azul de la mañana.

FLORENCIO DE LA SIERRA

Comentario.- Quien no le gusta observar una aurora al son del amanecer, el poeta lo saluda, desde su percepción pastoril, observando al  medio ambiente como las avecillas, los ríos y los árboles, saludan a la pupila azul, con una sonrisa al amanecer.

ESA : Beautiful science with astronaut aurora .- Hermosa ciencia con la aurora del astronauta

http://www.esa.int/Our_Activities/Human_Spaceflight/Research/Beautiful_science_with_astronaut_aurora





The Milky-Way and Aurora Australis

Beautiful science with astronaut aurora

16 March 2017 
Some of the most wonderful pictures taken by astronauts from space are of aurora dancing over our planet. Now the photos are more than just pretty pictures thanks to an ESA project that makes them scientifically usable.
Aurora offer a visual means to study space weather, the conditions in the upper regions of our atmosphere. These colourful displays are produced when electrically charged particles from the Sun in the solar wind are channelled along Earth’s magnetic field lines and strike atoms high in the atmosphere.
Just as the Sun is instrumental to the weather on Earth, solar activity influences space weather, which in turn can interfere with radio transmissions, satellites and even our electricity supply.

From above and below – and straight through

Thick green fog of aurora
 
Scientists study space weather and aurora using satellites such as ESA’s Cluster and Proba-2 but also through a network of cameras on the ground. These cameras are often obscured by cloud or snow and coverage from the southern hemisphere is poor because there is not much land at the best latitudes for observing the aurora.  
Pictures taken from the International Space Station can provide context and add information by improving estimates of the height and length of aurora. Some reach 500 km high – meaning the Station sometimes flies right through them.

Looking to the stars to find out when and where

Geo-referencing astronauts' auroral photography to further their use in research
 
First, the images need to be turned into something that scientists can use. Most important is to know the exact time and where the camera was pointing.
The images are downloaded in the highest resolution and faulty camera pixels from cosmic radiation are removed. Software corrects distortion from the camera lens.
Just like 19th century explorers before navigation satellites existed, ESA’s team looked to the stars for reference, using software to identify the stars in the image, and from there calculate the precise position of each pixel and its scale.
Last, the image time is determined by linking cities with their calculated locations and the horizon.
Software engineer and ESA young graduate trainee Maik Riechert, who worked on the project, explains: “The ideal images for processing are pictures showing Earth and the stars with the horizon just above the middle.”

Putting it all together

When all the images are processed, the timelapse videos offer a way to check the process went smoothly. Any jitter or changes in star tracking will show up in the final video, so a smooth run proves that the individual images are ready for analysis.
Now it is over to the scientists who can use the extra information in their research. Find the full dataset on the automatic geo-referencing of astronaut auroral photography webpage. A paper describing the method is available here.
ESA’s Andrew Walsh, manager for this project, concludes “This project shows that nothing is wasted and you can get useful science from unusual sources.”

NASA : Aurora and Manicouagan Crater .- Aurora Boreal y cráter Manicouagan

http://www.nasa.gov/image-feature/aurora-and-manicouagan-cráter

Aurora in brilliant green photographed from orbit with Earth below and crater visible on landscape
An astronaut aboard the International Space Station adjusted the camera for night imaging and captured the green veils and curtains of an aurora that spanned thousands of kilometers over Quebec, Canada.
 
Snow and ice in this winter image, acquired on Feb. 3, 2012, reflect enough light from stars, the moon, and the aurora to reveal details of the landscape. On the lower right, we see a circle of ice on the frozen reservoir that now occupies Manicouagan impact crater (70 kilometers in diameter). City lights reveal small settlements, such as Labrador City (an iron-ore mining town) and the Royal Canadian Air Force base at Goose Bay on the Labrador Sea.
 
The aurora borealis (northern lights) is the light that glows when charged particles from the magnetosphere (the magnetic space around Earth) are accelerated by storms from the sun. The particles collide with atoms in the atmosphere; the green and red colors, for instance, are caused by the release of photons by oxygen atoms.
 
The fainter arc of light that parallels the horizon is known as airglow. This is another manifestation of the interaction of the Earth’s atmosphere with radiation from the sun.
 
The atmosphere shields life on Earth from the sun’s harmful radiation. It also causes small asteroids to burn up or catastrophically explode before hitting the ground. Larger asteroids can occasionally penetrate the atmosphere and collide with our rocky planet—with dramatic effects.

Geologists know that a large asteroid slammed into Earth roughly 214 million years ago, creating a crater about 100 kilometers (60 miles) across on the landmass that is now part of Canada. The impact caused a shock wave to radiate across Earth’s surface, followed closely by high-velocity winds. Near the impact point, wind speeds would have exceeded 1000 kilometers (600 miles) per hour. The shock wave and air blast would have severely damaged and killed plants and animals out to distances of approximately 560 kilometers (350 miles)—as far as Goose Bay. After erosion by glaciers and other processes over millions of years, the Manicouagan crater is now about 60 kilometers (37 miles) wide.

NASA : Aurora South of Australia .- Aurora al Sur de Australia

http://www.nasa.gov/image-feature/aurora-south-of-Australia

Looping green aurora over Earth with clouds and sea visible below
On June 24, 2016, Expedition 48 Commander Jeff Williams of NASA photographed the brilliant lights of an aurora from the International Space Station. Sharing the image on social media, Williams wrote, "We were treated to some spectacular aurora south of Australia today." 
The dancing lights of the aurora provide stunning views, but also capture the imagination of scientists who study incoming energy and particles from the sun. Aurora are one effect of such energetic particles, which can speed out from the sun both in a steady stream called the solar wind and due to giant eruptions known as coronal mass ejections or CMEs.

NASA : Solar Storms Ignite X-ray "Northern Lights" on Jupiter .- De rayos X solares tormentas Ignite "Luces del Norte" en Jupiter

Hola amigos: A VUELO DE UN QUINDE EL BLOG., Las tormentas solares están provocando auroras de rayos X en Júpiter que son cerca de ocho veces más brillante de lo normal en una amplia zona del planeta y cientos de veces más energía que la Tierra "luces del norte", de acuerdo con un nuevo estudio usando datos de Chandra X de la NASA Observatorio de rayos. Este resultado es la primera vez que las auroras de Júpiter han sido estudiados a la luz de rayos X cuando una tormenta solar gigante llegó al planeta.

Solar storms are triggering X-ray auroras on Jupiter that are about eight times brighter than normal over a large area of the planet and hundreds of times more energetic than Earth’s "northern lights," according to a new study using data from NASA’s Chandra X-ray Observatory. This result is the first time that Jupiter's auroras have been studied in X-ray light when a giant solar storm arrived at the planet.
 
The Sun constantly ejects streams of particles into space in the solar wind. Sometimes, giant storms, known as coronal mass ejections (CMEs), erupt and the winds become much stronger. These events compress Jupiter's magnetosphere, the region of space controlled by Jupiter's magnetic field, shifting its boundary with the solar wind inward by more than a million miles. This new study found that the interaction at the boundary triggers the X-rays in Jupiter's auroras, which cover an area bigger than the surface of the Earth.
These composite images show Jupiter and its aurora during and after a CME's arrival at Jupiter in October 2011. In these images, X-ray data from Chandra (purple) have been overlaid on an optical image from the Hubble Space Telescope. The left-hand panel reveals the X-ray activity when the CME reached Jupiter, and the right-hand side is the view two days later after the CME subsided. The impact of the CME on Jupiter's aurora was tracked by monitoring the X-rays emitted during two 11-hour observations. The scientists used that data to pinpoint the source of the X-ray activity and identify areas to investigate further at different time points. They plan to find out how the X-rays form by collecting data on Jupiter's magnetic field, magnetosphere and aurora using Chandra and ESA’s XMM-Newton.
A paper describing these results appeared in the March 22, 2016 issue of the Journal of Geophysical Research. The authors on the paper are William Dunn (UCL), Graziella Branduardi-Raymont (UCL), Ronald Elsner (NASA's Marshall Space Flight Center), Marissa Vogt (Boston University), Laurent Lamy (University of Paris Diderot), Peter Ford (Massachusetts Institute of Technology), Andrew Coates (UCL), Randall Gladstone (Southwest Research Institute), Caitriona Jackman (University of Southampton), Jonathan Nichols (University of Leicester), Jonathan Rae (UCL), Ali Varsani (UCL), Tomoki Kimura (JAXA), Kenneth Hansen (University of Michigan), and Jamie Jasinski (UCL).

nsf.gov - National Science Foundation - Springtime night lights: Finding the aurora .- Luces de la noche de la primavera: Encontrar la aurora

Hola amigos: A VUELO DE UN QUINDE EL BLOG., hemos recibido información de la Fundación Nacional de Ciencias de Los Estados Unidos, dándonos conocimiento de la formación y vistas de las Auroras en el Hemisferio Norte. En realidad las auroras son una danza de partículas y magnetismo entre El Sol y La Tierra. Como sabemos El Sol constantemente produce vientos cargados de partículas o plasma y la llega a la Tierra como un "Aliento", que el campo magnético de la Tierra lo hace cambiar en forma redonda a largada, como si fuese una lágrima con una larga cola en la parte más alejada de El Sol.

This is the seventh part in a series on NSF's geosciences risk and resilience interest area. See parts one, two, three, four, five and six.
Dance of the spirits, it's known by the Cree, one of North America's largest groups of Native Americans.
The phenomenon, called the aurora borealis in the Northern Hemisphere and aurora australis in the Southern Hemisphere, is indeed a dance of particles and magnetism between the sun and the Earth.
The sun continuously produces a solar wind of charged particles, or plasma. As that "breath" reaches Earth, it causes our planet's magnetic field to shapeshift from round to teardrop--with a long tail on the side farthest from the sun.
The teardrop-stretched field ultimately reconfigures into two parts, one controlled by Earth's magnetic field, the other by the solar wind.
The instability excites the solar-charged particles. They follow spiral paths along lines connecting Earth's north and south magnetic poles to its atmosphere.
"What happens next," says scientist Elizabeth MacDonald of the New Mexico Consortium in Los Alamos, "is one of nature's most spectacular sights: the aurora."
The light of the aurora is emitted when the charged particles collide with gases in Earth's upper atmosphere.
 
Glimpsing an aurora
 
How often the aurora is visible in an area, MacDonald says, depends upon a host of factors, including the intensity of the solar wind; the season--the aurora may be strongest around the spring and fall equinoxes; whether the sun is near the peak of its 11-year cycle; and how far someone is from what scientists call the auroral oval, the lights' ring-shaped display.
Knowing where and when an aurora is happening has been difficult to find out--until now. A new project called Aurorasaurus allows citizens around the world to track auroras and report on their progress. Aurorasaurus is designed by researchers from the New Mexico Consortium, Pennsylvania State University and Science Education Solutions.
Visitors to the Aurorasaurus website can see where an aurora is happening in real-time, let other Aurorasaurus visitors know of an aurora's existence, and receive "early warnings" when an aurora is likely to happen in their Earth-neighborhood.
 
Aurora-power
 
"Auroras are beautiful displays that have fascinated humans through the ages," says Therese Moretto Jorgensen, program director in the National Science Foundation's (NSF) Directorate for Geosciences, which, along with NSF's Directorate for Education and Human Resources and Directorate for Computer & Information Science & Engineering, funds Aurorasaurus through NSF's INSPIRE program.
INSPIRE supports projects whose scientific advances lie outside the scope of a single program or discipline, lines of research that promise transformational advances, and prospective discoveries at the interfaces of scientific boundaries.
"Auroras are of major interest," says Moretto Jorgensen, "because of their effects on Earth. There's a close relationship between auroras and the magnetic variations that pose a threat to the power grid.
"A better understanding of when and where auroras happen will help us develop models that can forecast these potentially hazardous events."
 
Amassing new data
 
Scientists hope that by amassing data from thousands of aurora-viewers, they'll learn more about the solar storms that can disrupt or destroy Earth's communications networks and affect the planet's navigation, pipeline, electrical and transportation systems.
During one solar storm in 1989, transformers in New Jersey melted and wiped out power all the way to Quebec, leaving millions of people in the dark.
The largest such solar storm in history, the Carrington Event, zapped Earth in 1859. It was so large it lit up the skies with auroras from the poles to the tropics. Electrical currents from the storm caused fires in telegraph systems and knocked out communications.
 
St. Patrick's Day magic in the skies
 
Could it happen again? Yes, if St. Patrick's Day this year is any guide.
On March 17, 2015, researchers and the public were treated to once-a-decade views. As people waited for glimpses of leprechauns, they saw something even more magical, viewers say.
Earth experienced the biggest solar storm to date of this 11-year sun cycle, sparking auroras around the world.
The St. Patrick's Day auroras, many of which were indeed green, were a fortuitous combination of events. Two days earlier, there was an explosion on the sun. The explosion, called a coronal mass ejection (CME), unleashed a blast of gas bubbles that created a strong disturbance as it collided with Earth's magnetic field.
The CME's magnetic field was directed southward, opposite to the Earth's magnetic field, and the solar wind whipped by very fast, says MacDonald.
"The storm's conditions led to a perfect environment for aurora-hunting," she says. On a scale of G1 (minor) to G5 (extreme), the storm reached a G4, or "severe" level.
The storm's Kp index, a global solar storm index, registered in the 6-8 range (9 is the highest).
 
Rare aurora-viewing--all the way to the southern U.S.
 
The strong solar wind blew for more than 24 hours, creating auroras visible as far south as the central and southern United States--a very rare occurrence.
The solar storm's peak hit during the daytime over most of the United States and Europe, but the storm persisted into the night and offered Americans and Europeans a brilliant nighttime light show.
Aurorasaurus reports came in from unusual regions: the south of England, Germany and Poland. In the United States, people spotted auroras in states such as Pennsylvania, Virginia and Colorado.
 
Data peak from Aurorasaurus users
 
Aurorasaurus participants logged more than 160 sightings during the St. Patrick's Day solar storm.
From midnight on March 17th through mid-day on March 18th, the number of registered users increased by 50 percent. Registering allows Aurorasaurus to communicate information in return, sending location-based sighting alerts.
"We combine reports to provide real-time alerts when auroras might be visible nearby," says MacDonald. "During this storm alone, we issued 361 such notifications.
"We're using Aurorasaurus data to improve auroral oval models, and to develop a better notification system using both satellite-based data and citizen science data."
Adds Moretto Jorgensen, "Auroras on a global scale are very difficult to capture using traditional scientific methods. Human observers linked through Aurorasaurus are a unique network for documenting them."
Whether on St. Patrick's Day or any other Earth-day, the aurora carries a message: take time to look up at one of the planet's most breathtaking sights.
Then look down, to be sure you can send photos of the event from your cell phone. Spirits dancing across the skies may have played havoc with its transmissions.

Sounding Rockets Launch Into an Aurora
The interaction of solar winds and Earth’s atmosphere produces northern lights, or auroras, that dance across the night sky and mesmerize the casual observer. However, to scientists this interaction is more than a light display. It produces many questions about the role it plays in Earth’s meteorological processes and the impact on the planet’s atmosphere.
To help answer some of these questions, NASA suborbital sounding rockets carrying university-developed experiments -- the Mesosphere-Lower Thermosphere Turbulence Experiment (M-TeX) and Mesospheric Inversion-layer Stratified Turbulence (MIST) -- were launched into auroras from the Poker Flat Research Range in Alaska. The experiments explore the Earth’s atmosphere’s response to auroral, radiation belt and solar energetic particles and associated effects on nitric oxide and ozone.
This composite shot of all four sounding rockets for the M-TeX and MIST experiments is made up of 30 second exposures. The rocket salvo began at 4:13 a.m. EST, Jan. 26, 2015. A fifth rocket carrying the Auroral Spatial Structures Probe remains ready on the launch pad. The launch window for this experiment runs through Jan. 27.
