Sunspots July 2011

In July the Sun was shining much, and I was able to do observations in 20 days. The Solar activity has been in high level during July, and I got the highest monthly average so far this year in July, the average Wolf’s number in July was 51,05.

Nevertheless, there was a short period with quiet activity in late July. Anyway, the activity was increasing again during the last days of July, which was also indicated by the birth of three gigantic sunspot groups, that are still visible in the Sun while I’m writing this! For example Spaceweather.com -site was reprting about those huge sunspots! And actually I when I was cheking the sunspots today, I was finally able to see two of those gigantic spots also with naked eye!

And finally the table of my sunspot observations from July:

And the graph:

With sunny greetings,
