What great afternoon.

This is a image taken at 13:07, I have altered the hue to bring out some of the detail. It was taken with the Societies Solar Scope and my Canon 600D using a x2 Barlow.

Bill and I also watched the final phase of this event through my Lunt 'scope from the front of the Britannia Hotel, which has a good view towards the Western horizon. I saw the third contact myself.
We were also able to show it to several members of the Bolton Wireless Club, as they arrived for a meeting.

I've made an animation of five images which I took through the day: the first two from Bolton School, followed by three from my back garden.

Each image was formed from a stack (in AutoStakkert) of the best of 300-frame .AVI files, captured using wxAstrocapture from a monochrome Philips webcam attached to my Lunt LS35T 'scope. Then I used IRIS to apply wavelet filtering, set the colour-balance and even add the time-stamps.
But I was left with the problem that each image was framed differently and had a different orientation, so I ended up measuring the positions of a pair of sunspots on each frame and using the FILE_ROT and FILE_TRANS commands in IRIS to register on these.
Finally I output the sequence as .BMPs, converted them to .GIFs in IrfanView, and then used unFREEz to stitch them into the animated-GIF.
