The sun is waking up. After several quiet years, it
bombarded the Earth with two consecutive solar storms this week, which
generated many nights of spectacular auroras seen from backyards around
the Northern Hemisphere.
A relatively powerful flare burst from the sun’s surface
on Jan. 19, throwing off charged particles that reached our planet on
Jan. 22. But this was nothing compared to the enormous flare that erupted the next day.
The biggest solar flare in six years, this impressive event propelled a
gigantic, fast-moving storm that reached Earth on Jan. 24.
The Earth’s magnetic field directs the torrent of charged particles
from these storms toward the poles. Interactions with the atmosphere
produce the wavering lines of beautiful color known as auroras, or
Northern Lights.
Because the sun is now entering a more active part of its solar
cycle, the next few months and years are expected to see more frequent
solar storms. Just today, it produced
an X-class solar flare, the most powerful category of flare. Though
this particular one was not directed at Earth, such events can damage
satellites and screw up communications on Earth.
Despite these drawbacks, increased solar storms mean more pretty
auroras. Here, we indulge in some incredible views taken by ordinary
folk of these atmospheric light shows. Above:
Eagle Lights

a bird, flanked by a radiant wingspan. The photo was taken in
