    News is just coming through of a possible 12th mag. Nova in Aquila. See..http://www.cbat.eps.harvard.edu/unconf/followups/J18523496-0018423.htmlDiscovered by Japanese observers Koichi Nishiyama & Fujio Kabashima on Oct 20.429.The image on the link at the bottom of the cbat page is pretty convincing!Gary

    David,Thanks for showing an interest. I can remember a time when a possible Nova would have been quite the news! How times change.It still has it’s ‘PNV’ designation, and I haven’t seen details of a spectrum anywhere. Lots of observations and images of course, but without a spectrum it remains a ‘possible Nova’ (PNV).It is an extremely red object, and unfiltered CCD images are showing the Nova much brighter than visual or V band. The difference between I&V band photometry is around 4 magnitudes at the moment (latest data from Nick James using Sierra Stars on Oct 26.11 UT is 10.25I & 14.32V).There are some images – including a multi-band animation from Denis Buczynski – on the VSS web pages.Gary

    I got some photometry on this again tonight but haven’t reduced it yet. On Tuesday it was:2012-10-30.84 – V=14.18, Rc=12.32, Ic=10.26 i.e. around 4 mags fainter in V than Ic. Most unfiltered CCDs at the moment will probably get it around the Rc value.
