* - 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 CBET and ATEL circulars.   Data also comes from IAU's Transient Name Server web page.   These web pages have brought you the latest in supernovae data and images since April 1997.   21 years and counting.

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

News: 2018ctv is in a cluster between NGC 545 and NGC 541.   2018cow was originally classified as a galactic nova, and is now a bright type Ic-BL.   2018aoz (Type Ia in NGC 3923) is now fading.   2018zd is a Type II in nearby NGC 2146.   2017eaw (Type II in NGC 6946), is our most prolific galaxy with now 10 supernovae is still visible.   The IAU's Transient Name Server is now the official way to post your discoveries.   This is the TNS getting started page.   For supernovae light curves, look at the new Open supernova Catalog (see OSC links).   For the year 2018, 3333 supernovae (496 CBAT, 2548 unconfirmed, and 289 other sources) have been reported. (7114 last year)   The brightest SN of the year is 2018aoz (Mag 12.7) and 2018pv (Mag 12.7) followed by 2018gv (Mag 12.8).  

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: 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.   I am (re)starting a supernova e-mail list.   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.
