Today all of Earth celebrated the June solstice, as the sun reached its northernmost point in our sky. After today, the sun’s path will be shifting southward. There’s a big sunspot region on the sun now. Sunspot region AR3038 has increased in size, by the diameter of another Earth in just the last 24 hours. In addition, three coronal holes have appeared on the solar disk. These will provide high-speed solar wind, expected to impact Earth on June 23. Solar flare activity is low with only C-class flares from AR3030, AR3031 (now out of view), and AR3038. Eleven C flares have occurred since yesterday. Images show the sun from directly overhead early this afternoon, with area 3038 annotated, and, the inverse image showing some of the solar flare activity.
