V1454 CYGNI
Pavol Dubovsky has reported that the UGSU ROP star V1454 Cyg is in 
outburst. On 2012 May 10.93UT the visual estimate was 15.3. Pavol 
recorded on 2012 May 01.03UT that the object was not seen and fainter 
than magnitude 15.3.

Ian Miller confirmed the outburst on 2012 May 11.97UT with the 
unfiltered CCD magnitude, 15.2. He added that time-series photometry 
clearly demonstrating 0.15-mag superhumps. Astrometry gave a positional 
measure: RA 19 53 38.47 DEC +35 21 45.8 (+/-0.12") with result in 
agreement with that in Downes CV catalogue.

Gary Poyner mentions that the previously observed outburst was in August 
2009. His own most recent result at 15.4v was on May 13.03UT.
