[vsnet-alert 15024] Re: Possible magnitude 12 nova in Aquila

[Gianluca Masi]

Dear Colleagues,

the object was remotely imaged by Gianluca Masi, Francesca
Nocentini and Patrick Schmeer with the 432mm-f/6.8 reflector
part of the Virtual Telescope Project (Ceccano, FR, Italy).

20-sec, unfiltered exposures were measured, using the NOMAD
catalogue (assuming its R mags for the comparison stars).

Astrometry follows (J2000.0):

18 52 34.98 -00 18 42.4 (>1000 reference stars; mean
residuals: 0.3" on both axes)

Photometry (unfiltered image, R-mag for the ref stars, mean
residual: 0.3 mag):
2012 10 20.73026:  11.4.

regards,
Gianluca Masi
