[vsnet-alert 17912] PNV J03093063+2638031:likely a dwarf nova?

[Gianluca Masi]

Dear Colleagues,

we performed low-res spectroscopy of this transient, remotely using the 14" 
robotic unit part of the Virtual Telescope in Italy.

300-seconds exposures were taken on 30.8125 Oct. UT, using a 100 lines/mm 
grating, with a dispersion of 34.5 angstroms/pixel: we do NOT see evidence of 
strong H-alpha emission.

We also performed time-resolved photometry of the source with the same 
telescope, found at mag 11.1 (R, unfiltered), seeing a 0.05 large modulation 
(early superhumps?).

Observations are ongoing.

Regards
