It’s #SunDay#! Here’s your space weather report for the week of July 3 - July 9: • 1 X-class flare • 36 M-class flares • 3 C-class flares • 42 coronal mass ejections • 1 geomagnetic storm This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. The Sun celebrated the fourth of July with a big bang, emitting an intense X-class solar flare ( and a burst of M-class flares. You can see the show starting at about 0:49 in the video.

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 storms This 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.

It’s #SunDay#! Here’s your space weather report for the week of April 17 - 23: •6 M-class flares •0 C-class flares •34 coronal mass ejections •1 geomagnetic storm This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. Two X-class flares erupted right after the end of this reporting period — they’ll be first up in next week’s space weather report! Another thing we *don’t* see here: comet PANSTARRS (C/2025 R3)! The comet is currently passing between the Sun and Earth, and ESA/NASA’s SOHO spacecraft is watching the comet as it streaks across the view of its C3 coronagraph. We'll share more views of that comet later; in the meantime, check the latest imagery here: Learn more about space weather:

It’s #SunDay#! Here’s your space weather report for the week of Aug 21 - 27: • 8 M-class flares • 3 C-class flares • 32 coronal mass ejections • 0 geomagnetic storms This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. Active region AR14513 — the bright cluster of activity that has made its way across the Sun’s disk this week, appearing in the center at about 2:10 in this video — produced all but two of this week’s flares, though none reached X-class. The strongest flare in this period was an M6.9, also produced by AR14513, appearing at about 1:57 in the video. It still has a few more days on the Earth-facing side of the Sun, so we'll keep watch!
