Comet Holmes
Comet in extreme outburst
Uploaded 10/24/07
There
has never been a comet quite like this one. This image, taken
during the nearly full moon shows a comet exhibiting an explosive
outburst, normally at 17th magnitude which has jumped to 2.8
or so. Seen as a naked eye tawny star in Perseus, this fall splendor
was only a few arc minutes in diamter and resembled the appearance
of a planetary nebula with a strong leaden yellow coloration
in the longer exposures.
This image is
a stack of many exposures to keep the core from blowing out,
which happens on anything over about 5 seconds exposure. More
on this one comming!
