Update Friday, August 5th:
Sunspot group 1260 has almost rotated off the Sun's visible disk, but the other two groups are still going strong.The biggest group. 1263, should remain spectacular well into next week. Check spaceweather.com for the latest on sunspots and aurora forecasts. The original story starts below.
The Sun has been getting more active ever since solar minimum ended last year, and this week it's putting on its best show in nearly a decade. Sunspot groups 1260, 1261, and 1263 look great through a properly filtered telescope, and 1261 and 1263 have both been spotted with no optical aid at all except a solar filter. All of these groups have blasted multiple flares aimed in our direction, so there’s also a good chance of aurora activity on the coming nights. If you have access to a solar filter, or some safe way to project an image of the Sun to share the views with a group, get out and enjoy some daytime astronomy!
