Position

Equatorial: 00^h55^m19.85^s, +46^d12^m56.9^s (Gaia)
Galactic: l= 123.63, b=-16.65

Finding Chart:

Bikmaev et al. (2006)

Brigntness:

Optical: G=14.8 (Gaia); X-rays: 1.9x10^-11 ergs cm^-2s^-1 (BAT 157m; 14-195 keV), 2.6x10^-11 ergs cm^-2s^-1 (4XMM-DR11)

IP Credential:

**** (Confirmed): The spin period is well-established through X-ray and optical observations. The orbital period is mainly infered from the spin and beat period (also seen in optical photometry), without precise determination from optical spectroscopy.

Periods:

Orbital: 0.1137953 d = 2.731087 hr = 9831.914 s (inferred)
Spin: 0.0053875571 d = 7.7580822 min = 465.48493 s, seen in X-ray and optical photometry.
BJD(max) = 2454743.146425 (23) + 0.0053875571 (8) E
(Kozhevnikov 2012) from optical photometry, also seen in X-rays (465.68 s with RXTE; the 469.75s period seen with XMM-Newton is likely to be a blend of this and the beat period)
Others: 0.005655303 d = 8.143637 min = 488.61822 s
BJD(max) = 2454743.150323 (20) + 0.0056553035 (10) E
(Kozhevnikov 2012) from optical photometry.
