It’s #SunDay#! Here’s your space weather report for the week of April 3 - 9:
•7 M-class flares
•1 M-class flares
•16 coronal mass ejections
•1 geomagnetic storm
This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity.
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 reporting period.
