This week’s geomagnetic storm peaked on April 3, sparking auroras around the arctic circle and reaching a strength classification of G3 (strong). The cause was a CME that erupted from the Sun late on April 1. Aside from that, the Sun was fairly quiet during this

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 stormThis 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 se
