Related: About this forumSunspot AR1785 is pointed right at us.
In less than 24 hours, AR1785 has stretched and lengthened by more than 40,000 km. It is now more than 11 times as wide as Earth, which makes the active region an easy target for backyard solar telescopes.
One thing hasn't changed: the sprawling sunspot group has a 'beta-gamma-delta' magnetic field that harbors energy for strong solar flares. Moreover, the shape-shifting of AR1785 could lead to explosive instabilities in the sunspot's magnetic canopy. NOAA forecasters estimate a 55% chance of M-class solar flares and a 10% chance of X-flares during the next 24 hours

Hopefully not a coronal mass ejection.
No fun in those unless it results on only aurora. Sometimes not. Some day global disaster.

They stopped at around age 15.

Really, CME gives me nightmares. We're so unprepared. We should be off-planet by now and spread out, but we're just SO DAMNED SLOW.

Isn't this what took out power a few years back?
