April 13th - AR2529 Update, White Light, 3.20pm.

My last frames, taken at 3.20pm with Equinox 80mm, Lunt H Wedge, Olympus E-M5, plus x2 barlow for close-up.

Taken about seven hours after my earliest frames this morning, the bridge going into the umbra looks a bit narrow and goes further into the umbra as it curves round to the South.  Also, where the bridge leaves the umbra (and enters the penumbra) on the W edge (thr right in the picture) it appears to split into two faintly visible channels which weren't evident before - at least not on my earlier frames.

Very nice Paul! I was seeing visual detail not unlike your close up yesterday, so much to see in there, and quite a lot of changes happening even during the course of a day.

Super close-up Paul. I tried some today but the seeing was appalling.

Many thanks Stu. I do agree with you about how fascinating it is to monitor a large and/or complex sunspot group.  As you say, they can change surprisingly quickly sometimes.

Many thanks David.  I agree with your comments on the seeing, it has been very poor around here.  Still, I'm glad to be able to have seen it at all.

Lovely WL close up Paul.

Very nice WL shots.

Nice close ups, features do change quickly on the Sun. It was one of the real surprises for me, when i first started Solar observing/imaging.
