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.   11 years and counting. .   For yesterday's updates, go back to the updates page. I guess I can archive these there (Useful?). Purchased a new state of the art computer, which I am still loading. If I missed loading your image, please resend it! Added images of 2008ge, 2008gd, 2008gb, and 2008fv Updated the entry for Nova M31 2008-07a (classic FeII nova) We have a possible supernova in NGC 539 (Discovery image) (T. Kryachko image) We have a possible supernova in NGC 3318 (Discovery image) (T. Kryachko image) Please see CBAT Unconformed observation page for possible supernovae. For the year 2008, 185 supernovae have been reported (584 last year).   The brightest supernova reported for the year so far is 2008ge at mag 12.2, followed by 2008bk at mag 12.5, 2008ax at mag 13.0, 2008fp at mag 13.5, and 2008Q at mag 13.5 .   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.   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.  CBAT has password protected all IAU Circulars.   Your password will be in your last subscription notice.  LOSS ask people who discover supernovae to provide an offset from a nearby star to make spectroscopy easier.   Three groups are not reporting all of their discovery to CBAT.   Because of this I have 3 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.
