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
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?

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.
