Not much happening, but here are the significant prominences for the last 2 days.

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!

Nice prominences and a new active region on the advancing limb.

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!
