All active supernova over mag 17.0
* - 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. Here you will find a list of the supernovae we can see right now, as well as information about where they are in the sky, images of that object and how bright the explosion was at the last time we measured it. 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. 27 years and counting. . For yesterday's updates, go to the updates page.
The page now detects if you have set Dark Mode on your browser, please tell me if the colors don't work for you. New User's manual. New version of the web page for cell phone users: https://www.RochesterAstronomy.org/snimages/sn.html. TNS has moved to a new URL: https://www.wis-tns.org/. To post your discoveries, go to the TNS getting started page. The Open supernova Catalog has died, links will be removed eventually. 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.   LOSS ask people who discover supernovae to provide an offset from a nearby star to make spectroscopy easier.

For Supernovae which have faded below 18th magnitude, you will have to look in the archives |
I plan to report only "bright" Supernova (above mag 17.5) on this page. Note that you are going to need a big telescope to find most of these things, for instance, a "Mag 14" SN probably won't be visible to the eye in anything less than a 10" telescope. A CCD, however, can often detect a Mag 14 object with a much smaller objective. Those SN which are easily findable by amateurs (above mag 14.0) will be in red.
The format is as follows:
If possible I will create an icon for every bright supernova. This icon will be black on a white background and mirror imaged left to right so that North is up and East is left. The exception being a color image, which will have he same orientation. All icons will be less than 100x100 pixels in size so that they load quickly.
Supernovae are officially designated in a scheme that includes the year followed (without a space) by one upper-case or two to four lower-case letters indicating the order of discovery, starting with A, B., ... Z, then aa, ab, ac, ..., az, ba, bb, ... zy, zz, aaa, aab, aac, ... aaz, aba, abb, abc, ... abz, ... Furthermore, due to politics, several supernova teams demand that their own survey designations be used instead of the standard system.
