Sol from the 13th of February 2019.

Post by eroel »

Hi:
Yesterday was very hazy and cloudy day, it later rained.
Tried to get some shots but it was very difficult because of the seeing as the SSM shows, and because the big prom was very dim,
Used the CaK mod and the Solarmax 90-DS.
The camera was the SKYnyx 2-2, a very reliable and nice but slow camera. (12fps)
Thanks for looking.
Eric.

Eric,

Even through less than ideal seeing those disks look fantastic. Man, can you catch proms!

Mighty fine full disks. Slow cameras are fine at this scale.

Absolute beauty in all the shots Eric :bow

I was wondering if you can spot polar faculae in your CaK images? The BAA at the moment is trying to get data this year on polar faculae (solar minimum) however not many of us take white light images. Do you think they would be able to use our CaK images instead?

A great series, Eric. I am glad you and others in the group were able to image that truly remarkable prom.

Alexandra, Phil, Rainer, Mike, Franco, Mark and Maurits:
Much appreciated comments, thanks.
Alexandra, Faculae usually appear at up to 35°N and S of the solar equator, but there are also some that appear at upper latitudes and up to the polar regions. The polar faculae is different in size and in lifetime (smaller and with a shorter life) and are more frequent during the solar minima.
I believe that CaK could show the polar faculae easier, as also a blue/green filter in white light imaging.
Best regards,
Eric.
