Today on the Sun:

Active Region 2443 has continued to be active. It produced an impulsive M1 flare and over a dozen C-class flares. This was the first M class flare since October 17th. The region grew and maintained it’s magnetic complexity. Expect more flaring from this region over the next 24 hours.

Coronal Hole responsible for the expected G3 Aurora for November 2nd and 3rd

The coronal hole pointed directly at Earth is producing a high speed wind stream that will impact Earth in a major way over the next couple days. SWPC has issued a G3-Strong geomagnetic watch for November 2nd and a a G2 (moderate) aurora watch for November 3rd. NLN has updated the 3-day forecast with the expected timings. These are based on the best data available but a +/- six hour window is possible. Either way, a strong storm is expected and it should reward aurora hunters. Above is an image of the coronal hole responsible for the potential storm, below, see the current timelines as currently predicted by SWPC.
