* - last observation is over one month old.  

A long time ago, in a galaxy far far away, a star exploded.   This star exploded so violently that for a few weeks the star outshone its parent galaxy.   This type of explosion is called a Supernova.   The last one in our galaxy was 400 years ago, making us about 300 years overdue for the next one.   On this web page you will find a list of the currently observable supernovae, along with information on their location, reference images, and their last reported brightness.   The data on this page comes from TNS and ATEL circulars.   These web pages have brought you the latest in supernovae data and images since April 1997.   23 years and counting.

.   For yesterday's updates, go to the updates page.

News: 2020uxz is a young type Ia in NGC 514.   2020rcq in faint UGC 6930 is very bright. 2020nvb, 2020nlb, and 2020jfo are in solar conjunction.   I created isn_chat@googlegroups.com to replace isn_chat@yahoogroups.com.   For the year 2020, 15165 supernovae (1409 CBAT, 13754 unconfirmed, and 2 other sources) have been reported. (15827 last year).   The brightest SN of the year 2020 are 2020ue (Mag 11.8), followed by 2020hvf (Mag 12.4), and 2020nvb (Mag 13.0)

To post your discoveries, go to the TNS getting started page.   For supernovae light curves, look at the new Open supernova Catalog (see OSC links).   Latest Supernovae is now supported by Purdue University and maintains a new mirror hosted in the Department of Physics and Astronomy that is overseen by Dan Milisavljevic.   Purdue mirror page: http://www.physics.purdue.edu/brightsupernovae/.   New features: Modifed the sorted by name list to include removed objects and mark "non public" objects. All galactic objects (CV novae, etc) will be banished on a weekly basis to the boneyard.   Thanks for all of the images, I have been posting them on flickr.   Join the discussion! Facebook Supernova Enthusiasts Group.   The Active supernovae page is a version of this page which is designed to be easier to read.   I've done extensive work recently in the Archives.   If anybody knows who some of the "unknown" discoverers are, please let me know.   Does anybody know of a grant that I could apply to for supporting this page? I probably spend about 2 hours a night working on it.   Please note my backup e-mail address: dbishopx at gmail.com .  To turn off the icons, use this link.   With the demise of of Yahoo Groups, I am moving isn_chat to Google groups.   Please sign up if interested.   VSNet is partially back up!   LOSS ask people who discover supernovae to provide an offset from a nearby star to make spectroscopy easier.
