Still solid cloud for me so not managed a look yet Sad

Hey Brian, notice your CaK PST shot is full disk, do you use the DMK41 or have you got a focal reducer on there? If you are using focal reducer which one is it please?  Can't quite get a full disk with the DMK31....

I can see i'm going to have a 'fleet' if DMKs before long.    Roll Eyes  I already want a colour 21 for planatry stuff, and the benefits of a 41 are obvious to me aswell.  Better start saving some coin...  Tongue

In the time that I had in the afternoon I got this shot of AR 1027. Conditions were not great with only small gaps in the cloud which did'nt last long. There seems to be more umbra than penumbra with this one! Is it starting to decay already?

Nice shot John, it's not easy to capture the "rice grain" granulation - I'm clouded out & the weather looks depressingly settled....

This AR (1027) looks about fully developed. It will probably start to decay now.

Good sunny sky here this afternoon. I got a look at the solar disk in white light and can't see AR1026 at all. My scope is shaking like mad in the wind so perhaps it's too small to see in these conditions. Either that or it has completely decayed. It released a weak C-class flare this morning.

AR1027 looks in good shape but I sense it could be weakening too.

Thanks lads!

Martin, AR 1026 is still there but you need to look really hard to see it and the scope needs to be steady. It's only a tiny dot in the middle of some faculae and will probably be gone by tomorrow. It should though still be a nice AR in something like Ha as there is still activity in and around it. I managed some avi of 1027 but have yet to see what it's like, I was plagued by cloud all afternoon and now it's clearing when the sun's too low to do anything Angry

Ah, thanks for the info John, that explains why I didn't see it. I must find a sheltered spot around the house next time. Cheers.

Nice job on SW by the way, that's a great result!.

Wouldn't it be just great if 1027 released a flare now, pointing directly towards the Earth too. At least the Sun is more lively, I hope this is the start of a new trend.

Thanks Martin re SW, as you know it can be a bit hit and miss! Here's my offering from today, nothing brilliant but at least a result. I think 1027 is already going downhill but who knows with sunspots, look at 1026 blasting off a flare today and there's hardly anything visible.
This is 1027 in the afternoon.

And all I could get of 1026.

Sat 26th: Got a 5 min "sucker hole" and managed observations in CaK and a quick peek in white light before the cloud rolled back in. AR1026 appears to be gone as a white light feature but the plage area is still very large, complex & bright in CaK. AR1027 looks much the same as John's image above, two smallish spots well seperated; there may be more pores which I was unable to see through the cloud.

AR 1026:

2009 Sep 2009, 0846 UT, PST CaK @ f/20

AR 1027:

2009 Sep 2009, 0844 UT, PST CaK @ f/20

No more cloud holes so far (in fact a very solid grey overcast  Angry)

Two cracking shots Brian, the detail is outstanding Shocked I had a visual in a very short gap abd I couldn't see 1026 anywhere. 1027 just looks like two large pores with no penumbra. Roll on the next one! Brian, you should send those in to SW.com! BTW did you not get the chance to look in Ha?

Great job John and Brian, those are crackers!.

Had a visual look at midday before it clouded over. AR1026 has gone completely in white light and although 1027 is obvious it looked weakened. Hopefully there will be more to come.

I was really disappointed when I woke up this morning and it was cloudy (again!), however much to my pleasant surprise about 2ish blue skies appeared! However there was a caveat - my parents are staying this weekend and were due to arrive shortly after 3.  Our garden is essentially 2 parking spaces with pots and planters around the edges, so i knew when they did arrive I would have no space for the scopes, getting them to park away from the house isn't an option as both are pensioners and it's being a bit cheeky to ask this of them.  This meant only one thing - I had to be a solar stormtrooper and just get on with the imaging, no messing about.  So that's what I did...

All images below were taken between 13.00-14.00ut.

Starting with CaK, I was mesmerised by the view, until now all I had seen of the CaK disk through the CaK PST was the speckled duck egg blue disk; todays is alot more active.  Wink

Starting off, AR11027 CaK PST @ f30 DMK31



Naturally the next one is AR11026 CaK PST @ f30 DMK31



Next a 'near' full disk view, seeing that the sky was nice and blue I thought i'd have a go at proms in CaK, the big beastie showed up quite well, though I find it fascinating the difference in structure visible with CaK and Ha views.  There's a few dust bunnies hopping around to try and torment me, but i'm not going to let them bother me Wink

CaK PST @ f10 DMK31



Next we go to the Ha views, with a monster prom and 2 active regions there was plenty to go at today...  Starting wide and zooming in, the first here is taken with the SM40 @f10 with the DMK31.  I'm really tempted to get me a DMK41 just to get whole disk in both Ha & CaK...



Next is the big prom and AR11027 with the SM40 @ f16, DMK31.



At the other side of the disk was a smaller prom and the swirling mass of AR11026.  SM40 @ f16 DMK31



Finally, the monster prom with the SM40 @ f30 DMK31



I'm happy given the time I had with the results i've got.  Also with the processing i've tried to back off a bit with the wavelets in Registax.

Hope you like the pickies!

Best wishes,
Mark Smiley
