Bright Supernova - Archives
On these pages you will find references to Supernovae which have
faded into oblivion. Occasionally I will have to resurrect a
supernova out of the archives because it will be found to still be
visible, but that is a rare occurrence.
Typically I will place a supernova
in the archive if it gets dimmer than 18th mag, and nobody has looked
at it for two months. Exceptions to this rule are typically type II
supernovae which are in solar conjunction, which I will keep on the
page with a "solar conjunction note".
I try to keep the links up to date, but as web pages come and go I often have no idea that things have been moved or removed. If you do know what happened to a link that no long works, please tell me so that I can relink it.
You can see how the pages have evolved here as well. I started these pages in April of 1997. It started out as "Supernovae in NGC and IC galaxies", until I was convinced that some non NGC and IC supernovae actually got brighter some NGC and IC ones. Then it change to "Bright Supernovae", as I planned only to report supernovae above 18th magnitude. Now I just report everything. However, I don't create a full entry for any supernova which can't get above mag 18. Finally, in 1999, when I took over the International Supernova Network's Latest Supernovae page I retitled the main page "Latest Supernovae", BUT, it's the "Latest Supernovae" page of the "Bright Supernovae" pages which are also sub-pages of ISN.
