NASA : Images of the Sun From the GOES-16 Satellite .- Imágenes del Sol Desde el Satélite GOES-16

These images of the sun were captured at the same time on January 29, 2017 by the six channels on the Solar Ultraviolet Imager or SUVI instrument aboard NOAA’s GOES-16 satellite. They show a large coronal hole in the sun’s southern hemisphere. Data from SUVI will provide an estimation of coronal plasma temperatures and emission measurements which are important to space weather forecasting.

 

SUVI is essential to understanding active areas on the sun, solar flares and eruptions that may lead to coronal mass ejections which may impact Earth. Depending on the magnitude of a particular eruption, a geomagnetic storm can result that is powerful enough to disturb Earth’s magnetic field. Such an event may impact power grids by tripping circuit breakers, disrupt communication and satellite data collection by causing short-wave radio interference and damage orbiting satellites and their electronics. SUVI will allow the NOAA Space Weather Prediction Center to provide early space weather warnings to electric power companies, telecommunication providers and satellite operators.

NASA successfully launched GOES-R at 6:42 p.m. EST on November 19, 2016 from Cape Canaveral Air Force Station in Florida. It was renamed GOES-16 when it achieved orbit. GOES-16 is now observing the planet from an equatorial view approximately 22,300 miles above the surface of the Earth.

Satellite View of the Americas on Earth Day

Today, April 22, 2014 is Earth Day, and what better way to celebrate than taking a look at our home planet from space.

NOAA's GOES-East satellite captured this stunning view of the Americas on Earth Day, April 22, 2014 at 11:45 UTC/7:45 a.m. EDT. The data from GOES-East was made into an image by the NASA/NOAA GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md.

In North America, clouds associated with a cold front stretch from Montreal, Canada, south through the Tennessee Valley, and southwest to southern Texas bringing rain east of the front today. A low pressure area in the Pacific Northwest is expected to bring rainfall in Oregon, Washington, Idaho, stretching into the upper Midwest, according to NOAA's National Weather Service. That low is also expected to bring precipitation north into the provinces of British Columbia and Alberta, Canada. Another Pacific low is moving over southern Nevada and the National Weather Service expects rain from that system to fall in central California, Nevada, and northern Utah.

Near the equator, GOES imagery shows a line of pop up thunderstorms. Those thunderstorms are associated with the Intertropical Convergence Zone (ITCZ). The ITCZ encircles the Earth near the equator.

In South America, convective (rapidly rising air that condenses and forms clouds) thunderstorms pepper Colombia, Venezuela, Ecuador, Peru, Bolivia, Paraguay and northwestern and southeastern Brazil.

GOES satellites provide the kind of continuous monitoring necessary for intensive data analysis. Geostationary describes an orbit in which a satellite is always in the same position with respect to the rotating Earth. This allows GOES to hover continuously over one position on Earth's surface, appearing stationary. As a result, GOES provide a constant vigil for the atmospheric "triggers" for severe weather conditions such as tornadoes, flash floods, hail storms and hurricanes.

NASA : Three Atmospheric 'Dragons': Low Pressure Areas Around the U.S.

Three Atmospheric 'Dragons': Low Pressure Areas Around the U.S.

There are three low pressure systems around the U.S. and they resemble dragons on satellite imagery. NOAA's GOES-13 and GOES-15 satellite image from March 31, 2014 shows the low pressure systems in the eastern Pacific Ocean, over the nation's Heartland, and in the eastern Atlantic Ocean. All three lows have the signature comma shape that make them appear to be curled up dragons.

According to the National Weather Service, the low pressure area approaching the northwestern U.S. is expected to bring rainfall to the coast and areas of snow that stretch from western Washington state south toward the four corners region. The low in the middle of the country is located over Nebraska and dropping snow to the north and west of it. That same low is bringing rain from southern Minnesota south to eastern Texas. Meanwhile, the third low pressure system is bringing rain and snow to parts of New England.

NOAA's GOES-East satellite sits in a fixed orbit in space capturing visible and infrared imagery of all weather over the eastern U.S. and Atlantic Ocean.

The data to create this image was taken on March 31, 2014 at 17:45 UTC/1:45 p.m. EDT by NOAA's GOES-East or GOES-13 satellite and made into an image by NASA/NOAA's GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md.
