Active Sun 12 Apr

Recommended Posts

The Sun is getting pretty active these days. Three major areas of activity in the northern hemisphere, the group just to the east of the meridian (AR 11190) looks quite "flary" in my Ha closeup.

Interesting activity on the NE limb where a new AR is rotating into view. The bright projection was actually brighter than the disc in Ha!

There is an interesting "detached" prominence on the SSW limb ...

... and a huge, complex and beautiful one on the NW limb, which shower clouds prevented me from doing full justice to.

I did not get a chance to make observations in white light or closeups in CaK but I did get whole disk images in CaK and Ha.
