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.
