This page is devoted to information on Supernova 1999by in NGC 2841. Basic information on this SN, including the last reported brightness, on this Supernova can be found on the Bright supernova - 1999 page. Information on the original web pages for many of these images can be found on the Supernova links web page.
Maximum brightness on this supernova occurred sometime around May 12th 1999 when it reached mag 13.2 (computed by taking an average of the observations done that day). This SN is now starting to slowly fade. There is a bright star (mag about 11.1) located 11".7 west and 29".5 north of the supernova.
I decided to take a couple of days off and visit my folks up in the
St. Lawrence river valley. When I got back I discovered this SN
backed up in my e-mail folder. 1999by was discovered by both Ron Arbour
and the Lick Observatory Supernova Search team while it was
still getting brighter. This SN is already the brightest this year, passing
1999ac and
1999aa
very quickly.
