Solar Activity M-Class Flare 1153

February 9, 2011

I have the iPhone app, Solar Monitor, and picked up a report of an M-Class solar flare last night. Space Weather reports:

SOLAR ACTIVITY HEATS UP: Formerly quiet sunspot 1153 is suddenly crackling with C- and M-class solar flares. NASA Solar Dynamics Observatory recorded this eruption during the waning hours of Feb. 8th: Because sunspot 1153 is rounding the sun’s western horizon, these eruptions are not Earth-directed. They are, however, Venus-directed. The second planet from the sun could receive glancing blows from solar plasma clouds in the days ahead. Readers with solar telescopes are encouraged to monitor the action.

NOAA Space Weather Prediction Center reports:

February 9, 2011 — Four, that’s right, four new active regions popped up on the Sun yesterday. However, it was their older brethren, Region 11153 which appeared on Feb 4th, that finally decided to make some noise, giving us a moderately large M1.9 Solar Flare. This region has grown in size over the past two days and remains poised with the potential to produce some large solar flares. It’s running out of time though, as it will rotate off the visible disk in two days time. We’ll be keeping a close eye on Region 11153 and the four new regions in case they want to cause any more trouble.
