Interesting to see how quickly AR 11422 developed. There was a single pore in 20120218:

That's a great comparison Pedro! I'm keeping my fingers crossed for some clear skies this weekend - would be nice to get some solar in before the month end...

Mark, cant you look at the sun during the day at lunchtime? Bring your portable PST in the trunk! (boot)

Hi Pedro

very fine job, thank you for sharing

That is quite a phenomenal development overnight!

However, if you measure the distance from the bottom spot to the active region I think baby AR11422 is just off the photo to the left in the first picture? (if the image scale is the same)

Yes Alexandra, you're right. I included the link to a pic where you can see AR11422 as a single pore (20120218):

Yes! excellent, I was surprised that there wouldn't be at least a pore visible, this confirms it.

Great pictures Pedro!
