Supernova 1999gn in M61
This page is devoted to information on
Supernova 1999gn in
NGC 4303
(= M61)
Basic information on this SN, including the last reported brightness,
on this Supernova can be found on the main
supernova page. Information on
the original web pages for many of these images can be found on the
Supernova links web page.
Amateur Alessandro Dimai reported via
ISN
his discovery of a new star in
M61. According to the rules, amateurs need two
observations on two different nights to confirm a new supernova. Thus,
ISN activated its' "isn_alert" SIG, which puts us in contact with
amateur and professional supernova hunters around the world. Within
hours, Weidong Li from
LOSS had confirmed his observations and it was off
to IAU
for an official designation.
