Supernova 1999gi in NGC 3184

This page is devoted to information on Supernova 1999gi in NGC 3184. Basic information on this SN, including the last reported brightness, on this Supernova can be found on the main page. Information on the original web pages for many of these images can be found on the Supernova links web page.

Amateur Reiki Kushida found this one at Yatsugatake South Base Observatory, it her 8th supernova discovery. NGC 3184 is a fairly close Mag 10.3 galaxy, only about half as distant as the Virgo cluster. Supernova 1999gi is a dimmer type II (which very in maximum brightness), but this one could get as bright as Mag 13.2. I normally wait until I have several images of an SN before I start a page for it, but the amount of data on this SN is quickly passing the amount of data I got for 1999em

Web pages dedicated to this SN.

AAVSO almost immediately issued aavso-alert 267 with information on this SN and some very nice finder charts

AUDE has a 1999gi page in French [Translate]

Seiichi Yoshida has a 1999gi page
