First solar observing session - which sunspot is this

[dav1d]

So, I made a filter from Baader solar film, a box of cheap wine and some cardboard and spent a happy half hour under a towel this afternoon.

I took a couple of pictures which included a big angry looking sunspot. Can anyone tell me what it is - my solar geography isn't up to much...

Its AR (Ative Region) 1486 - the big spot and AR 1491 - the two smaller spots to the lower left.

A tad out of focus, if I may say so and, with South at the top, "upside down" which confused me a bit . But not to worry, its good for a first picture:cool:.

Try: http://www.solen.info/solar/ (scroll down) for todays full disc image (with N at the top ). AR 1486 is a bit nearer the edge of the disc now, due to the rotation of the Sun.

That's very nice. What did you use to take the image? Is it prime focus? What did you do for the colour?

I'm off out in a mo to have a dabble too.

Thanks for the info Bizibilder - that looks well useful (if very complicated) SanMatt, I used my Desire HD afocally through a 25mm EP on my 130p. I stuck it into Irfanview & cropped then fiddled with contrast & colour correction until it was as clear and contrasty as possible.

Thanks, chaps!
