[vsnet-alert 15772] Re: [cvnet-outburst] Re: PNV J19150199+0719471

[Arne Henden]

Astrometry from AAVSOnet W30:
19:15:02.03 +07:19:46.7
Photometry from W30 on HJD 2456444.8707
V = 10.642
(B-V) = -0.081
(V-Rc) = -0.003
(Rc-Ic) = -0.035

I have seen novae with this color (basically A0), and the field does not
look heavily reddened to me from inspection of a few field stars (I haven't
looked at the APASS photometry).  I'd wait until spectroscopic confirmation
before deciding nova/WZ Sge classification.
