Only one previous outburst of this cataclysmic variable has been recorded
(cf. vsnet-obs 18078 below).  
 
USNO-A2.0 data for TmzV85:
R.A. 10h43m57.097s  Decl. +58o07'33.20" (J2000.0) r= 16.2, b= 16.4

Arne Henden's data:
R.A. 10h43m56.81s   Decl. +58o07'32.6"  (J2000.0) V= 17.906, B-V= +0.191

Time-resolved photometry and spectroscopy during the current outburst are
very urgently required.

The images were confirmed on two patrol films. I have checked known
minor planet.

of 13.0-<15.3p.
