NASA Space Alerts(@NASASpaceAlerts):It’s #SunDay! Here’s your space weather report for the week of July 10 - July 16: • 1 M-class flare • 3 C-class flares • 29 coronal mass ejections • 0 geomagnetic storms This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. Those “blackouts” in the video below aren’t missing data — those are Earth eclipses! SDO is currently in its 33rd Earth eclipse season, which began on July 5 and will continue through August 2. Eclipse seasons are three-week periods twice a year when the spacecraft’s orbit passes “behind” Earth, briefly blocking out SDO's view of the Sun each day.
