On this page you will find a list of the updates most recently made to the
Bright Supernovae web pages.
I am putting this page in place as many people surf my pages on a daily
basis and want to know what the updates are. If you find this valuable,
please give me some feedback .
It does take considerable time to keep the "updates" page updated.
On image credits:
If the "from" credit is an external link, then I linked to
an image on that page.
If it is a relative link, then the image is loaded locally.
Note that I normally don't record updates I make from
VSNet .
I update magnitudes and add notes from them on an almost daily basis.
Occasionally I make a mistake. Please see the
Errata section for a list of these.
If you find
one, or a broken link, please e-mail me
and I will fix it. I maintain these pages with an ASCII editor (no web
publishing tools involved at ALL) and I occasionally make a typo which
escapes my QC checks.
