Beginning to wonder if my first assessment might have been the right one? I’ve had a closer look at some of the images and my little blob of pixels has moved slightly in some of the shots. Whilst the Sun rotates and first to last shot was as much as 90 minutes apart I don’t think this accounts for the movement and I’m back to wondering if it might be an error on the CCD. I can’t find it on previous images but I will try to think of something to be used as a test shot and have a close look at it. The other possibility that occurs to me is some minute damage to the solar film used to bring the Sun down to manageable proportions for viewing. The film reduces the throughput by 99.99% and whilst there is no problem discernable to Mk1 eyeball maybe the CCD has recorded something.
The photos that were linked from spaceweather.com were all tight shots of the area of activity and did not show the exact location, so I will have another look tomorrow to see if I can find something which gives a better indication of the location.
