QQ Vul

QQ Vul is an AM Her star with a P_orb of 3.7 hours.  The orbital variations are in the order of 1.5 magnitudes (see below).  Much of the variations shown above are due to the orbital period.   Low states reach magnitude <17.5V.  QQ Vul may also display eclipses.  See http://www.aas.org/publications/baas/v30n4/aas193/271.htm

The light curve is compiled from unfiltered CCD observations, obtained with the Bradford Robotic Telescope, and V-band observations obtained with the Sonoita Research Observatory (through the AAVSO).

QQ Vul is observed as part of the BAAVSS Long Term Polar Monitoring Programme
