This cataclysmic system is observed flickering


V1193 VOri is a cataclysmic binary, that is with an accreting white dwarf. It is classified as a "nova like" but it does not seem to be much studied. According to Papadaki et al (2004) there is an orbital modulation with a period of 3.96h and an amplitude of 0.05 mag.

This is a CBA target for Dec 2006.


The observations were carried out with a 203mm SC telescope, a Clear filter and a SBIG ST7E camera (KAF401E CCD). Each image has a duration of 60s.

The comparison star is GSC 4752-01223 with an assumed unfiltered magnitude of 12.0 and the check star is GSC 4752-01202.

The light curves:

Red: V1193 Ori. Blue: the checkstar, shifted by +1.0 magnitude. The error bars are +/- the 1 sigma statistical uncertainties. Some clouds towards the end.
