Special Notice #202: Classical nova event in V407 Cyg

March 14, 2010: Further to Munari et al. (CBET 2204, D.W.E. Green, editor), the presumed symbiotic star V407 Cyg is exhibiting spectral features clearly indicating a classical nova of the He/N type. This strongly suggests that the white dwarf component of the system is currently undergoing a nova outburst rather than a symbiotic-type outburst. The spectral evolution of this nova may be very fast given the likely large mass loss rate of the Mira-type donor star. We urgently request observations of V407 Cyg to provide photometric coverage of this unique event.

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

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.
