Development of AR12674 from last two weeks (EdgeHD 11, broadband)
Hello,
here are some images from this nice active region from when it appeared at the eastern limb, until it disappeard at the western limb.
My first imaging was on Monday, August 21:
Next day, it was better visible:
During these days in August, I had very nice seeing. This continued on Wednesday:
One cloudy day inbetween, next imaging was on Friday. Everything began to get smaller:
On saturday, the following (on the left) spot had massively shrunk:
On sunday, not much had changed: Some shape variation of the preceeding (large) spot, some minor rearrangement in the following (left) spots:
On tuesday of the second week, not much has changed: the preceeding spot is more circular shaped, but now in north-south direction:
On wednesday, the large (precedding) spot is circular with a slight elongation in north-south direction:
The following day, I wasn't able to image, and then this nice active region had disappeared behind the limb.
This is only part of the data from the last two weeks. There is still quite some more left, but I'm afraid, it will take some time until I will have analysed everything.
Enjoy,
Laura

Your location is super nice for solar imaging! Such a seeing (for example 0,1"/0,19"/0,40" and others) is fantastic. No need to visit 3000mt mounting tops like Mt St Veran.
BTW. Can you, please, show the best (or one of the best) frame from the movie where the seeing was (as mentioned above)? This will tellus are these SSM return values real or just SSM's creation.
Thanks in advance.

Thanks, Frédéric and Valery!
@Valery: That's a project I planned anyway. I already archived all raw data and need to restore them. This will probably take a few days because of other obligations interfering with solar imaging but I'll come back with the images soon.
Best, Laura

Great set of images!
I was interested in the clarity of the granulation...it seems, as probably expected, that the granulation is more defined closer to the centre of the solar disk.....
Well done.
(It would be good to see comparison images with a Continuum filter or an OIII filter...)

Thanks, Ken. Please note that the type of filter is given in the image legend just behind AR number, date and time. The first three and the last two images are made with SolarContinuum: Is this what you were looking for?
@Valery: to shorten the time, please see for a video of my dara the end of the first post in my AR12671 thread:
viewtopic.php?f=4&t=23238&p=210368#p210368
There, I have given a video. Please note, that this is only an unprocessed and compressed subset (first 100 images) of the original video for file size reasons. On that occasion, I was imaging with the 35nm Halpha filter through high clouds, e.g.transparency was not perfect.
Best, Laura

I now saw this video. Now looking for the video from the session when the seeng was 0,1"/0,19"/0,40" . Should be something remarkable.
