A beautiful Melbourne day but unfortunately the seeing was only average with a high jet stream. The sun itself was very impressive with huge filaments, complex active regions and some interesting proms.
Ha images taken with Solar Scout 60 double stacked with a Lunt 40mm etalon, full disk with 0.5 focal reducer and ASI178MM.
Close up shows AR 3053 and 3055. Also some very long filaments.
Very nice results, ARs' Filaments and Proms everywhere and you have captured them nicely. Still jealous that Melbourne is getting more sunshine than we, north of the border, though today has dawned with a clear blue sky so maybe I can get my gear out for a look. Ground is still saturated though.

Thanks Jeff. Fingers crossed you get to see the sun a bit more from now on.
We just can't believe how bad the weather has been up north this year! You must be sick of it.
My son and I visually witnessed a flare at approx 2:05pm Sunday afternoon (Melb time) in our Lunt 40. A small yet intensely bright U-shaped loop that grew and dissipated all within 15mins or so. It was fascinating to watch it change so quickly!
Do you happen to have any data from that time period? I've circled the location on a copy of your pic (see below).

Lots to see on the sun at the moment!

Hi Dean and William,
We have a Lunt 40 as well and have found it to be a fantastic scope. Unfortunately we don't have any further images later on that day. One of the best sources (usually) of Ha data is the GONG site. https://gong2.nso.edu/products/table...igs/hAlpha.cfg
The site that is most useful for viewing our times is Learmonth in WA. Presently their images are broken. It looks like their Quantum Ha filter has gone badly out of tune and their images have next to no detail. As you can see, quite a few of the other sites are collecting good detail at the moment but 2.05pm (04:05UT) puts it in the night for many of the other sites. We have checked and couldn't find that particular time, however the region you marked did flare again a few hours later.
The sun is putting on a particularly impressive display this week. If you get a chance to view again through our less than great weather, it will be well worth it.
