Hi My Friends: A VUELO DE UN QUINDE EL BLOG., A stunning image showing Aurora Australis – the Southern Lights –
glowing over Concordia station in the Antarctic, one of the remotest
places on Earth, on 18 July 2012. It was taken by ESA-sponsored
scientist Alexander Kumar and his colleague Erick Bondoux from about 1
km from the station, located in the Antarctic at 75°S latitude.
The ethereal green glow of Aurora Australis high over Concordia station
on 18 July 2012. It was taken by ESA-sponsored scientist Alexander Kumar
and his colleague Erick Bondoux from about 1 km from the station,
located in the Antarctic at –75°S latitude.
The French–Italian Concordia station's programme of research includes
glaciology, human biology and the atmosphere. ESA uses the base to
prepare for future long-duration missions beyond Earth. During the
winter, Concordia is under almost total darkness, with an average
temperature of –51°C and a record low of –85°C. It is an ideal place to
study the effects on small, multicultural teams isolated for long
periods in an extreme, hostile environment.
Auroras occur frequently over both the North and South polar
regions, but are often difficult to see from populated areas. During
periods of increased solar activity, the lights sometimes extend to
populated latitudes. This year has seen unusually high solar activity;
most recently, on 14 July, Northern Lights could be seen as far south as
Duluth, Minnesota, USA.

Solar activity remains unusually high
On 17 July, the ESA/NASA SOHO mission captured an image of a spectacular solar flare, which unfolded over a period of several hours.

The effects at Earth are expected to be minor, but could include some effects on satellites in orbit or interference in high-frequency radio communications.
On 19 July 2012, the ESA/NASA SOHO mission captured an image of a solar
flare, which occurred around 5:58 UTC. The CME associated with this
flare seems to be directed to the west and will most likely not reach
Earth.

And still more...
Yet another flare occurred on 19 July, when solar active region NOAA AR 1520 produced an M7.7-class flare around 05:58 GMT.

The flare generated a coronal mass ejection that is directed to the west and will most likely not reach Earth.
However, a rapid increase in proton particles has been detected, and these have some effects on satellites.
Tracking space weather
“It is important to monitor, track and assess space weather events such as solar flares and especially the solar energetic particle events and coronal mass ejections sometimes associated with them,” says Juha-Pekka Luntama, manager of the space weather segment in ESA’s Space Situational Awareness programme office.

“Such events are capable of affecting space-based
telecommunications, broadcasting, meteorological observations and
navigation through to power distribution and terrestrial communications,
especially at northern latitudes.”
