Evolution of a Sunspot region!

2/28/2014

0 Comments

 
Sunspots traveling along the solar disc can vary quite a lot, sometimes their lifespans can be measured in a matter of hours and other times it can be months. Over the past few months we have been lucky to witness one such long lived sunspot, some pictures of which I have shown in earlier posts. AR11944 returned to be renamed AR11967 and now this spot has returned to be named AR11990 in a dramatic fashion releasing a huge X5 class solar flare to announce it's return.

So here I have compiled 3 different crops of the same sunspot over it's current life, you can quite clearly see how the sunspot changes size and shape over the period with AR11990 currently being the smallest incarnation of our solar visitor.

I do apologise for the lack of consistency between the pictures, it happens. Just remember that for some perspective on the size of these spots that the largest region of AR11944 could of easily contained 3 planet Earths.

Here is a nice full disc and close up of sunspot region 11967, you may recall the huge spot AR11944 from an earlier post. Well this is the same sunspot that has traveled full circle around the sun and was re-numbered upon it's re-emergence.

The crescent Moon was on show last night just before setting so as I had my gear out thought I'd have a go at capturing it.
It's not one of the sharpest images around but still it breaks up all the solar posts.
