Position

• Equatorial: 21^h33^m43.65^s, +51^d07' 24.5" (J2000)

  (From Catalog and Atlas of Cataclysmic Variables, Archival Edition)

• Galactic: l=94.46, b=-0.48

Finding Chart:

Motch et al. 1998

Brigntness:

Optical: B~15.8; X-rays: 0.42 c/s ROSAT PSPC.

Periods:

• Orbital: 0.2997 d = 7.1935 hr = 25896.7 s, from optical spectroscopy.

  HJD = 2453208.1428(28) + 0.29973(67)E

  (Bonnet-Bidaud et al. 2006) for blue-to-red crossing of emission lines.
• Spin: 0.0066067 d = 9.51365 min = 570.8189 s, seen in optical and X-ray photometry.

  HJD = 2452876.94785(3) + 0.0066067(2)E

  for the optical maxima.
• Others:

Inclination:

<45 deg

Distance:

>600 pc

Orbital and spin periods appear to be secure, given the lengths of observing runs relative to the infered periods. The same spin period is also seen in XMM X-ray data (presented at the XMM conference in 2005 September).
