A little activity today. A bar-type prominence and some detached plasma.

Only faint prominences this morning, but some details visible after a bit of processing.

Sun today – prominence development. 28/06/2019

Yesterday’s prominences had developed nicely this morning.

Later – I’ve now added the disc image.

This prominence/flare was very short-lived. It blew its top shortly after I got the image. Here are the GONG images +/- 3 hours from my image.

Another Solar post -flare loop? 19/06/2019

Posted June 16, 2019 by Roger Samworth

This morning I was trying to snatch some images in gaps in the clouds and I got this one. I was immediately struck by the similarity to the image I posted back in February https://roslistonastronomy.uk/strange-solar-phenomenon-02-07-2019

After some debate with the BAA and “Sky at Night” magazine (April “Message of the Month” it was concluded that this was a “post flare loop”

Again, this one was on all 200 frames of my basic .avi.

So I consulted the GONG web-site again, but unfortunately the only camera available for the time in question was the El Teide one. This camera’s images are always pretty poor, but also attached is a composite if its images bracketing the time of my image. I did a screen-grab and enhanced the contrast in GIMP in order to see anything at all. You can make out the prominence on all the frames (just)!, but I fancy the only frame that contains the feature I saw is the 10:49 one.

GONG images:

An interesting filament system is appearing at the advancing limb.

One of the nice things about solar imaging is that things change over a short time interval, exemplified by this morning’s prominences over a period of 07:26 to 09:50 UT.
