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 stormThis 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

It’s #SunDay! This week’s (Sept. 19 - 25) space weather report includes: · 4 M-class flares · 30 coronal mass ejections · 0 geomagnetic storms This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. At about 1:25 in the video, another celestial body makes an appearance — the Moon! Lunar transits happen only a few times a year, when the Moon’s tilted orbit aligns just right to cross SDO’s view. From SDO's orbit vantage point about 22,217 miles overhead, the Moon appears

It’s #SunDay! Here’s your space weather report for the week of April 24 - 30:• 2 X-class flares• 14 M-class flares• 18 coronal mass ejections• 0 geomagnetic stormsThis video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s solar activity. Two X-class flares erupt on the right side of the disk at the beginning of the week. On April 29, a few spacecraft calibration maneuvers make it look like the Sun is dancing.Find out more about flares & coronal mass ejections:
