Dear all,

I observed this star last night (2006-09-13/14 21-01 UT) at Hankasalmi
observatory in Finland with 40 cm RCOS telescope and STL-1001E CCD. The
star was at V=10.4 (AAVSO 135 ref) and showed very small amplitude
variation (0.03 min-max). Because of bad weather the period
determination will be difficult, but it looks like there could be
something around 3 hrs.

Visual magnitude estimates by P. Schmeer, Bischmisheim, Germany:
UMASW 20060912.14  <130 SPK
UMASW 20060913.149  108 SPK
UMASW 20060914.138  104 SPK

Instrument: 203-mm SCT
Sequence: AAVSO

Rare superoutburst of this SU UMa-type dwarf nova.
The last observed outburst (also a supermaximum) occurred nearly
four years ago - independently detected by Eddy Muyllaert on 2002
Oct. 24.191 UT at mv= 10.8 (vsnet-alert 7558) and by me on
Oct. 24.195 UT at mv= 11.3 (vsnet-alert 7559).

Time-resolved photometry is strongly recommended.
J2000.0 coordinates:  R.A. 08h36m42.74s  Decl. +53o28'38.1"
 
Regards,
Patrick
