Position

Equatorial: 23^h34^m01.55^s, +39^d21^m42.9^s (J2000)
Galactic: l=106.99, b=-21.10

Finding Chart:

Araujo-Betancor et al. (2005)

Brigntness:

Optical R~16/5; fx (2-10 keV)~?

IP Credential:

*** (Probable): Evidence for its IP nature appears solid; however, since this sytesm also has so many other features that it seems prudent to ask for independent confirmations.

Periods:

Orbital: 0.05630921 d = 1.351421 hr = 4865.116 s, from the shallow eclipses.
HJD = 2451812.67765(35) + 0.05630921(1)E
(Araujo-Betancor et al. 2005) for the times of mid-eclipse.
Spin: 0.000778 d = 1.12 min = 67.2 s, seen in optical photometry.
Others: 83.38 min permanent superhump period; ~3.5 hr spectroscopic period (not strictly coherent); 5-6 min white dwarf pulsation periods.
