Nova Centauri 2013: Another bright, naked-eye nova

Nova Centauri 2013 -- now named V1369 Cen -- is another bright nova in our skies for 2013.  Discovered by Australian observer John Seach on December 2nd, Nova Cen has now surpassed Nova Del 2013's maximum at 4th magnitude, and began a complicated evolution to (thus far) two separate maxima brighter than 3.5.  Nova Cen should put on a wonderful show for southern hemisphere observers for the end of the year, and may well continue well into 2014!  We'll post updates to this page as we learn more about this bright southern nova.  Meanwhile, we encourage all southern hemisph

Alert Notice 372: Possible naked-eye gamma ray burst detected (GRB 080319B)

March 19, 2008: The intense gamma-ray burst GRB 080319B was detected in gamma ray, x-ray, optical light, and early indications by two automated cameras suggest that the optical afterglow of the burst may have briefly reached naked-eye visibility (mag ~ 5.76, GCN 7445, Cwiok et al) within 60 seconds of the onset. It is highly unlikely the burst was caught visually, but it is possible the burst may have been detected if any observers were monitoring this area of the sky (e.g. for minor planet searching).

The coordinates of the burst are:

Nova Delphini 2013: The story so far

Nova Delphini 2013 (also named V339 Del) is the biggest cosmic event in variable star astronomy this year, and this naked-eye nova is providing the community a wealth of new data on this important class of objects.  The amateur astronomical community has made an enormous contribution of data for Nova Del so far, and now is a good time to review all that's happened so far in this nova outburst, and how the amateur community has played a role.
