Sun spews out 28 solar flares within 7 days

Scientists have warned that more solar eruptions could follow over the next week or so.
The sun it seems has finally woken up following a particularly mellow period despite being at solar maximum, the peak of its 11-year activity cycle. Within the last week astronomers observed more than two-dozen solar flares with the potential for more to come.

The activity seems to be originating from a particularly energetic sunspot that will continue to face us for another week before rotating out of sight. A sunspot is a region of the sun that corresponds to intense magnetic activity. "You get a tangled bunch of magnetic fields, and they get too tangled and too stressed, they end up erupting," said NASA's Holly Gilbert.

Despite the intensity of the activity however there is little risk to us here on Earth. While solar flares can interfere with communication systems this tends not to happen and the Earth's atmosphere and magnetic field helps to protect us from the brunt of the solar radiation.

NASA SDO & NASA/ESA SOHO - Lots Of ActivityThere is lots of activity going on in this view of our Sun from October 25 to October 28, 2013.Here we are showing the view from two different instruments on two different spacecrafts. The view of the Sun is taken by my AIA instrument in the 304 wavelength. The outside is from the NASA/ESA SOHO mission and their LASCO C2 instrument. The LASCO instrument is a corongraph.A coronagraph is a telescope that is designed to block light coming from the solar disk, in order to see the extremely faint emission from the region around the Sun, called the coro...

After a rather quiet 11 year cycle peak, we are seeing a lot of activity. So, what happens if the Earth happens to be concurrently experiencing a geomagnetic field reversal? Given my limited understanding of Earth's geomagnetic field reversals, I am led to believe these can be temporary or permanent but that the Earth's protective magnetic field is slightly diminished. So, I would expect that alignment of high solar activity and a slightly diminished magnetic field on Earth would allow a higher than normal amount of radiation to reach the surface of the Earth. This prompted my curiosity as to ... [More]
