ASASSN-16ow has been discovered in outburst at coordinates 06:30:47.04,
+02:39:31.7 on 2016-12-13.48 UT at V~13.82 mag. A patrol reference image
for 2016-11-28.59 does not show the object down to a limiting 18.2 mag,
indicating an amplitude of at least 5 mag. The ASASSN webpage suggests
either a CV in outburst or a nova (given the low galactic latitude) as
the
likely explanation.
We have obtained a low resolution spectrum (range 3300-8000 Ang, dispersion
2.3 Ang/pix) of ASASSN-16ow on Dec 14.94 UT with the Asiago 1.22m telescope
+ B&C spectrograph. The spectrum has a blue continuum with very broad
Balmer lines in absorption. An emission core is visible in Halpha.
Overall, it supports ASASSN-16ow to be a cataclysmic variable in outburst.
