It’s #SunDay#! Here’s your space weather report for the week of May 1 - 7: •2 M-class flares •2 C-class flares •29 coronal mass ejections •1 geomagnetic storm This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. It has been a relatively quiet week on the Sun, with the two M-class flares erupting off the Sun’s western limb (right side from SDO’s view) and not producing much impact on Earth. However, a large active region will soon be rotating into Earth’s view — you can see it toward the end of this video emerging from the eastern limb (left side from SDO's view). Keep an eye out in the coming week for potential solar activity! Learn more about space weather:
