Abstract:
We present the UBV(RI)c photometry of the dwarf nova Tri 2008 =
OT J023839.1+355648 obtained during its superoutburst started on
October 25, 2008. The object can be classified as a WZ Sge-type dwarf
nova. The period of early superhumps 0.05307 days was detected in the
first 7 days of the superoutburst. The period of ordinary superhumps
0.053663 days, detected in days 8-23 of the superoutburst, is the
shortest one among WZ Sge-type objects. After one month, the dwarf
nova returned to its pre-outburst state. A sudden increase of activity
of the object during its quiescent stage was detected on January 11,
2009.
Description:
Our UBV(RI)C CCD observations were taken with the SBIG ST10-XME
camera mounted in the Newton focus of the 0.5m (f/5) reflector at the
Stara Lesna Observatory and with the Apogee 47p camera mounted in the
Cassegrain focus of the 0.6m (f/12.5) reflector at the Crimean
Laboratory of the Sternberg Astronomical Institute.
