Hi all

It was great to see AR 1035 completed a lap of the Sun and it is still considered active! I think it departed on the 20th December and was out of view until nowish.
It has been sputtering with C-class X-ray solar flares too! The region also displays a huge dark filament - a mass of gas suspended by magnetic fields over the chromosphere.

Imaged through Solarmax 40, 2.5 Powermate, DMK31 – AVI’s stacked and processed in Registax5.
Conditions were so so.

The first image is of the region departing (around the western limb) - 18 December - and image 2 is the same region reappearing over the eastern limb - from today.

Thanks for looking!

Great images but look very different. Any reason for the title change.

Looking good Matt, at least you bothered to get yours the right way up!

Cheers

Hi Malcolm
I think the numbers allocated for active regions only stand for the time we see them. If they make the full rotation it is assigned the next number - after 1035 came and went another 4 active regions formed so when 1035 rotated back into view it became 1040.
I guess in the good old days they had no way of really knowing if one active region was the same one or not - it makes sense I guess!
I hope this assists in your question.
Oh, thanks for looking!

Thanks Stuart - I only did this as I recently saw E is W and visa versa when it comes to such objects - I had to flip the image - I now use SOHO and this site http://www.spacew.com/sunnow/ as a reference and I will try to do so in the future.
In the past I just tried to get balanced images - I still reackon visual appeal is often better than accurate references.

Thanks for looking!

Hi Matt

Congratulations on making Spaceweather with your AR1040 images – top stuff! I see you have got 2 days front page coverage for these shots!

Cheers

Nice going Matt. Waiting patiently for the cloud to disappear here. Would like to get a turn at imaging this beast again. However I reckon this is a little further on from the previous 11035. I have been noticing that active regions seem to open up just a little further east from a previous active region. I suppose part of the magnetic knots erupting through the field.

Nice images.
