I did capture a region of disturbance and a prom for my efforts.

Solar Analemma. This outstanding image from Alexandra Hart taken over a period of 4 years charts the midday position of the sun in the sky throughout the year. The north–south component of the analemma results from the change in the Sun's declination due to the tilt of Earth's axis of rotation. The east–west component results from the nonuniform rate of change of the Sun's right ascension, governed by combined effects of Earth's axial tilt and orbital eccentricity.
Merry Christmas, Happy New Year and looking forward to a great solar cycle 25!

I hadn't planned to image today but a quick glance at GONG showed a nice looking surge prom developing so out I went. This was about 14:50 UT. By the time everything was setup and the etalon was up to temperature the show was over. I missed it. Maybe next time.

Re: June 1st images
That’s the way it goes sometimes, Phil. Usually it’s weather related.....just get set up and the clouds roll in to spoil the show.
Great images. Lots of lovely fine structures in that prom shot.

As always, thanks for the kind remarks. Definitely helps during the slow Solar season.

Excellent resolution at the edge. Fantastic spiculaes.
I see your etalon was somewhat off-band. Spiculaes better seen when an etalon is somewhat red shifted.
BTW. The seeing often is good just before clounds are rolled on.

Re: June 1st images
Valery, you are absolutely correct. I did set the etalon temperature approximately 1.5°C hotter (red) that normal.

Re: June 1st images
Hi Alfred,
Here is a pic of the setup. These images were taken without the Daystar Combo. It was replaced with an extension tube.
