There are two SDSS stars in a 4" radius.
The star identified as the CV candidate has one measure in SDSS9 but a star 
(SDSS J160512.83+102231.5) 4" away (a typical offset for ASASSN variables) 
has two measures with very different magnitudes (g= 23.0 and 26.3) and it is 
also MLS_J160512.8+102230 (only two measures at 22th CV mag.). But it looks 
very red. Maybe a red variable unrelated to the outburst?
I doubt anyone could get so deep to check it but accurate astrometry is 
desirable to properly identiy the CV candidate.

Cheers,
Sebastian
