Sunspot AR 11164 - 2nd March

Mark at Beaufort

Recommended Posts

This is now a large sunspot group which might produce some nice activity over the next 24/48 hours.

Viewed with PST and white light on the William Optics SD66. Some nice proms on eastern edge plus one on the northern hemisphere.

On the largest part of 1164 a small black line was visible in the PST but not white light.

Good to see the Sun again :)
