Abstract:
An analysis of V photometric light curves of the eclipsing cataclysmic
variable SDSS J150240.98+333423.9/NZ Boo obtained in April-June,
2012 with a CCD photometer using the 60-cm telescope of the Sternberg
Astronomical Institute's Crimean station is presented (based on more
than 750 images). The first observation was made ∼350-370 orbital
cycles after the beginning of the outburst of April 2012; all the
observations correspond to quiescence of the system. The orbital
period, P = 0.0589106(4)d, changed by no more than
ΔPorb/Porb∼2x10-5 during the more than 37200 orbital cycles
since the previous observations of the system.
Description:
We began our observations of the cataclysmic variable
J150240.98+333423.9 when we received information that an outburst of
the system had begun on April 1, 2012 from the Japanese site VSNET. We
also began photometric monitoring, but our first observations were
obtained only on April 23, 2012, due to poor weather conditions.
Our observations were obtained using a CCD photometer on the 60-cm
telescope of Moscow State University's Crimean station.
