Sun images from Melbourne Australia 17 March 2023 (only now just able to upload)
We are amazed at just how many posts we have missed over the last two days when we simply have not been able to get onto the forum at all. Obviously somehow or other, other people have managed it. Good to see that Stephen's hard work has finally got things back to normal. So here is the post we tried to make two days ago
It was supposed to be cloudy this morning (Friday) so we didn't intend to image at all, but it turned out to be mostly clear with just a few annoying clouds. So we set up late but the good news was that we could use our proper location and mount. We were a bit rushed so didn't bother with the SSM today, thinking we would just grab a full disk. But for the first time in ages we did try some Ha closeups with the 102mm refractor but they are "soft". The full disk still has that towering prom in the NW, a floating prom on the west that disappeared later in the day (interesting that we couldn't find any of the GONG sites showing it arriving or developing), a messy array of proms in the SW and a big filament in the SW that also lifted off later in the day.
We took a full disk mosaic in Ha. Yesterday we measured the towering prom in the NW to be about 130,000km, approx 10 Earths tall. Today it looked to be around 9 Earths tall. Still impressive however. We also took a close up of the central northern region of filaments and one of the south west active regions and messy array of proms.

Superb set of photos. Nice work.
I do not look at the sky with the eyes of an astronomer, but of a person looking for the beauty of nature.

Re: Sun images from Melbourne Australia 17 March 2023 (only now just able to upload)
Nice to see your captures Clare and Peter, I like the comparison with multiple Earths for the size of prominence! These few days were quite an eye candy for solar imaging. It is getting difficult to decide what target to pick up for timelapse when there are many good details available.

Excellent images, C&P. That’s a heck of a prominence.

I love the 'how many Earths can you fit' in that prominence these are great images of a fabulous Sun
The forum has only really been back to normal yesterday and today, I think everyone saved up their posts and submitted them all yesterday in one go
I must say the forum is lightning fast now
