SunDay#! Here’s your space weather report for the week of July 17 - July 23:

This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity.
It was a fairly calm week on the Sun as SDO’s daily Earth eclipses punctuate our view of the Sun. The spacecraft’s Earth eclipse season, which began on July 5, continues through August 2. Eclipse seasons are three-week periods twice a year when the spacecraft’s orbit passes “behind” Earth, briefly blocking out the Sun each day.
