ASTRO: Supernova 2007be in Spiral Galaxy UGC 7800
By the time I got to imaging this one my brain was frazzled from spending
about 4 hours showing over a hundred people stuff like planets, open clusters in Auriga and galaxies in Leo. As a result I didn't notice that this image was a little out of focus. SN 2007be is a Type II supernova discovered on April 7th by Stefano Moretti and Salvatore Tomasell. I measured it as magnitude 17.00 at 4:10 UT on April 21, 2007. UGC 7800 is one of the many dim background galaxies in Virgo. It's about a arc minute long and 15th magnitude. The image is a 15 minute exposure with an SBIG STL-1301E camera on an OGS 20-inch F/8.1 RC Cass. Measurements from TheSky show the image size is 13x16 arc minutes, with South at the top. The scale is .78 arc seconds per pixel. For more info see: http://www.kopernik.org/images/archive/u7800.htm George N |

George,
I was missing your supernova images :-) The galaxy itself is not too exciting, but that's not your fault ;-) Stefan "George Normandin" schrieb im Newsbeitrag ...
