Sol from the 4th of June 2018.

Post by eroel » Tue Jun 05, 2018 1:45 pm

Hi:
The usual CaK and Ha FD´s, taken with the Meade 102mm f/9 with a CaK PST mod and the Solarmax 90-DS.
Thanks for looking,
Eric.

Val:
Thank you.
Looks like the bright prominence shown at 11:00 in the Ha FD´s, did not show on the CaK ones, probably was not energetic enough.
In the CaK prominence FD`s, it is barely shown.
Regards,
Eric.

A lovely collection Eric, it is sad to see AR12712 disappear but there are some large proms in the east, we can only hope they are associated with something new :)

I always admire your high contrast disks, Eric.

Eric, I'm passing trough the posts.
I wonder the CaK proms on your pics.
Congrats!

Excellent images, as always, Eric; lots of contrast and detail.

There appears to be a 'seam' around the Sun in the third (and inverted fourth) image. Is this some sort of long range structure, I wonder?

Alexandra and guys, thanks for the comments.
Stu, I also saw that. BTW, you can see it in all the FD´s in CaK and in Ha, in some shots it looks much fainter.
In my workflow I always change the recording parameters on each FD, so that is why in some FD`s you can see more or less details.
The seam could be an alignment issue, I take always 1000 frames in SER at 12fps (that is as fast as the SKYnyx 2-2 goes at full resolution) and use 30% of them to make the final version.
Best regards to all,
Eric.

Hi Eric,

At what times were your CaK images captured on June 4th (in UT rather than local)?

Stu:
The first CaK "surface" SER recording was taken at 17:38 UTC.
The first CaK prominence SER recording was taken at 12:42 UTC.
The second CaK "Surface" SERrecording was taken at 12:46 UTC.
The second CaK prominence SER recording was taken at 12:49 UTC.
Thanks, hope it helps for what you are thinking.
Best wishes,
Eric.

Thanks, Eric. I was curious to see what SDO recorded at the same time.

I believe it is a real feature, rather than an image artefact. Maybe it's the result of some random alignment, or maybe it was nucleated at AR12712.

Thoughts anyone?

Stu:
When some time left, I will realign and restack again the SER files in different softwares, (Registax6 and AS!2 and AS!3) so to find if it is an alignment and stacked artifact.
Regards,
Eric.
