NASA Space Alerts(@NASASpaceAlerts):It’s #SunDay! Here’s your space weather report for the week of May 8 - 14: •1 M-class flare •1 C-class flare •31 coronal mass ejections •0 geomagnetic storms This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. The active region we spotted last week (which erupted with an M-class flare and a CME last Sunday) has moved across the Sun and is now center-disk. It’s right next to a coronal hole that unleashed a stream of fast solar wind to Earth. We’ll be watching both regions for continued activity this week. Learn more about space weather:
