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.  Most of the supernova information found on this page comes from IAU and CBET circulars and occasionally more data can be found on IAU's List of Recent Supernovae web page.   Information on the current brightness and much of the background information is provided by SNWeb.   These web pages have brought you the latest in supernovae data and images since April 1997.   13 years and counting. .   For yesterday's updates, go to the updates page. Created an entry for 2010gr (Mag 17.8 in UGC 2035) Updated the entry for Nova M33 2010-07a (observations) Added images of Nova M33 2010-07a (Mag 19.3), 2010gm (Mag 17.6), PTF10myz (Mag 18.3) and 2010gp (Mag 16.1) Caught up.. News: 2010ev is a Type Ia found young, and was the brightest SN of the year at Mag 13.7.   Please note my backup e-mail address: dbishopx at gmail.com   MPC has a new web page at http://www.minorplanetcenter.org/iau/mpc.html.   The "Mag" links to SNWeb have stopped working.   I've been told that this is a temporary problem, but I have stopped linking to them until they start working again.   Please see CBAT Unconfirmed observation page for possible supernovae. For the year 2010, 295 supernovae (190 CBAT, 105 other sources) have been reported. New feature to turn off the icons, use this link.   Wow, it looks like people really do read this web page, here is a great article that Doug Rich wrote about me.   Mike Schwartz of Tenagra Observatories, Ltd. has named Asteroid 1999 RH241 (70401) Davidbishop and 2005 TF152 (149968) Trondal.   Extragalactic Novae now have their own page at the top level.   I am (re)starting a supernova e-mail list.   Please sign up if interested.   VSNet is partially back up!   Please continue to email your observation to SNWeb as the magnitudes on the page are driven by these observations.   LOSS ask people who discover supernovae to provide an offset from a nearby star to make spectroscopy easier.   Four groups are not reporting all of their discoveries to CBAT.   Because of this I have active SN (above 18th mag) which have not been given designations by CBAT.

Do you have a Supernova image you are willing to share with others? Please tell me about it! Don't be a data miser, share your data with others! I prefer to link to images already at a location on the web, but if you send me an image (jpeg or gif preferred) I will post and index it.

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:

Name of SN, IAUC circular number (link to circular), Date which the supernova first appeared (Year/Month/Date format), Name of discoverers separated by a ";" (link to discovery site(s) if possible)
Name of galaxy (linked to a page describing this galaxy), RA and DEC of SN in J2000.0 coordinates (link to sky map of that area of the sky) [finder charts for SN if possible]
Directions to the SN from core of host galaxy, galaxy name (linked to a Photometry Reference image of that galaxy) [link to images of SN if possible]
Magnitude of SN when LAST reported (link to the source of the last report) (* = last observation is over one month old) ("date of maximum:maximum brightness" or "rising" if that information is available) Type of SN if reported. [Spectrum if possible] (Any data which reference this SN (IAUCs; VSNET; past SNe))
Any special pages dedicated to observing this SN, or a link to a sub page if enough data warrants it.

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.
