Supernova 1999em in NGC 1637
This page is devoted to information on
Supernova 1999em in
NGC 1637
Basic information on this SN, including the last reported brightness,
on this Supernova can be found on the main
main page.
Information on
the original web pages for many of these images can be found on the
Supernova links web page.
This one was a bright one.
NGC 1637 is a mag 11.4
galaxy in Eridinus, close to the Orion boarder (it's not far from Rigel).
It's also only about 1/3 as far away as the Virgo cluster.
Supernova 1999em was caught
fairly early, and could make it up to mag 11.
Maximum brightness appeared to be at mag 13.1 (normalized) on or
about 10/31/99.

Currently there's a big debate over what photometry to use for
this supernova. Three sets of reference stars have been posted, and
depending on which one you use, you get a different brightness.
As soon as this is straightened out, I'll try to normalize things.
