It’s #SunDay! Here’s your space weather report for the week of April 10 - 16:
• 30 coronal mass ejections (CMEs)
• 0 M-class flares
• 0 C-class flares associated with CMEs
• 0 geomagnetic storms
This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity, which was very quiet. Some C-class flares did occur on the Sun during this period, but none were associated with coronal mass ejections (CMEs) or other space weather events, so they are not reported here.
Active region AR4419 first rotates onto the solar disk from the eastern limb (upper left edge) at about 1:20 into the video, then comes alive with lots of crackles and bursts starting at about 2:00 and continuing through the end. Its activity contrasts with the two other active regions on the Sun, AR4415, which moves across the Sun’s equatorial region, and AR4416, in the upper hemisphere, both of which showcase steadier, smoother brightenings of coronal loops. We’ll be watching all of these regions of possible activity in the coming week.
