Not much happening, but here are the significant prominences for the last 2 days.
Soul and Elephant’s Trunk with L-Enhance filter
Got both of these last night. The L-enhance gives more stars than a Ha filter, but seems to require a lot less stretching to get results. Not a lot of SII/Hb in these, especially the soul.
I think these might work well as luminance layers over an RGB image. Looking forwards to using them on the Rosette and M45.

Transient “bubble” prominences – a project for Solar observers?
It may be that the transient “bubble”-shaped prominences I keep seeing are quite common. Once you get your eye in you can spot quite a few. They seem to be characterised by the bubble-type shape and being very short-lived. Not only were there the two I reported the other day, but there also seems to be one on yesterday’s image.I can’t confirm this as I only acquired one image sequence yesterday, and with GONG I can’t access yesterday’s movies. There is little sign of it on their 3-hour images bracketing the time of my image.I am convinced it is real and not an imaging artifact – it is an all 400 frames of my raw avi.It would certainly be interesting if someone with a better solar scope saw them. Although my 35mm on the window-sill has “instant availability”, it does have optical limitations! The GONG cameras are only 28mm aperture also, so they are similar in resolution to my set-up (albeit without the double-glazing!).The problem is catching them in progress!

Part of the Eastern Veil Nebula
Had a lovely clear sky last night so I had my first proper try at the Eastern Veil Nebula. Total exposure of 4 hours in 7 minute frames. I’m quite happy with how it turned out.

After a long period of inactivity, some reasonable prominences today.
Also, some very short-lived phenomena not unlike things I have seen before – see https://roslistonastronomy.uk/another-solar-post-flare-loop-19-06-2019
The one at “A” had all but disappeared 50 minutes later but another at “B” had appeared. Both had vanished 20 minutes after that.
That’s solar astronomy – things change!
