Photometry requested for SS Cyg
Abstract:
Dr. Mariko Kimura (RIKEN, Japan) requests AAVSO assistance in obtaining V and Rc photometry of the cataclysmic variable SS Cyg in support of an orbital period study.
Justification:
The X-ray flux of SS Cyg is now increasing and 10-times larger than usual. This object is brightest at X-ray wavelengths in these 25 years. The quiescent level of the optical luminosity is also rising. I consider that this increase of the optical baseline may be caused by the X-ray irradiation of the outer accretion disk and/or the secondary star. In this case, we could see the irradiation component of the secondary star becomes dominant in the orbital light curve.
