It’s #SunDay! Here’s your space weather report for Oct. 16-22: •2 M-class flares •0 C-class flares •24 coronal mass ejections •0 geomagnetic storms This video from NASA’s Solar Dynamics Observatory shows the week’s activity. Both of this week’s M-class flares came from active region AR14551. The first, an M1.3 on Oct. 16, appears as a small bright flash just below and to the right of the Sun’s center at about 0:17 in the video. The second, an M1.6 on Oct. 19, erupts at about 1:30, after the region had drifted about halfway to the western limb (right edge). From about 2:00 to the end, watch AR14551 rotate off the Sun’s lower right edge, with glowing coronal loops towering above the limb. Quite a farewell! 🌅 At about 2:29, a calibration maneuver briefly moves the Sun out of frame. More about flares and active regions: go.nasa.gov/3Naeuv9
