AR 10484, 2003/10/22

I observed the gigantic active region AR 10484 on Wednesday afternoon.
It was the one of the easiest to detect naked-eye sunspots that I've
ever beheld and was unmistakable through my polymer solar shades. I
was able to see considerable internal detail with my Celestron C4.5
Newtonian at 53, 72, and 82x. I also noted the CME producing sunspot
AR 10486 working its way in from the trailing limb.

We observed the Sun between 1300 and 1500 UT on 23 Oct through a narrow-band
H-alpha Daystar filter at University of London Observatory (England). The
equipment is mounted on the 1862 8-inch Cooke refractor. Remarkably good
seeing and some of the most amazing loop prominences coming from AR 10486.
Several intense bright spots in both regions. Also several filaments across
the surface of the chromosphere. There is a big prominence on the
opposite limb as well. The Sun was so dull only two weeks ago...now it's
really exciting. We obtained some video footage and will try to coadd a few
frames to produce images. A previous observation of a solar flare is on our
web site
