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.
