Position

• Equatorial: 22^h55^m18.00^s, -03^d10^m40.3^s (Gaia)
• Galactic: l=68.67, b=-53.34

Finding Chart:

Griffiths et al. (1980)

Brigntness:

Optical: G=13.2 (Gaia); X-rays: 3.1x10^-11 ergs cm^-2s^-1 (BAT 157m; 14-195 keV), 4.7x10^-11 ergs cm^-2s^-1 (4XMM-DR11)

IP Credential:

***** (Ironclad) Both the orbital and the spin periods have been established beyond doubts.

Periods:

• Orbital: 0.149625502 d = 3.591012 hr = 12927.6432 s, seen in optical and X-rays.

  HJD (max) = 2444864.21809 (1) + 0.149625502 (1) E

  (Bonnardeau 2015)
• Spin: 0.009319484 d = 13.42006 min = 805.2034 s, seen in X-ray and optical photometry.

  HJD = 2444883.92074 (37) + 0.009319484 (4) E -2.87 (30) x 10^-13 E²

  (Kaluzny & Semeniuk 1988) has now accumulated too much uncertainties to be useable
• Others: The 858.69 s sideband is more prominent than the spin period in the optical.

  HJD = 2445174.18142 (16) + 0.009938493 (2) (4) E -3.87 (25) x 10^-13 E²

  (Kaluzny & Semeniuk 1988)

Inclination:

~60 deg? (X-ray orbital dip, no eclipse).

Distance:

461.8 (457.2-465.6) pc (Gaia EDR3; parallax: 2.125+/-0.021 mas)
