It’s #SunDay! Here’s your space weather report for the week of May 22 - 28: • 1 M-class flare • 0 C-class flares • 46 coronal mass ejections • 0 geomagnetic storms This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. Most of the action this week was on the far side of the Sun, out of SDO’s view. However, we do see a good example of a prominence beginning at about 20 seconds into the video on the lower western limb (right side edge) of the Sun. Prominences are huge clouds of electrified gas called plasma suspended in the solar atmosphere. Learn more about space weather:
