Position

• Equatorial: 22^h17^m55.49^s, -08^d21^m05.4^s (J2000)

  The SIMBAD server returns 22^h17^m57.1^s, -08^d21^m11.2^s --- this is 25 arcsec or so off. The above is from the Downes & Shara (1993).

• Galactic: l=53.00, b=-49.16

Finding Chart:

Patterson & Steiner (1983)

Brigntness:

Optical ; fx (2-10 keV)~3.5x10^(-11) ergs/cm/cm/s (ASCA)

Periods:

• Orbital: 0.202 d = 4.84944 hr = 14738 s, see in optical and X-rays.

  HJD = 2444782.869(2) + 0.2020596(1)E

  (Patterson et al 1998b) for the orbital dip.
• Spin: 0.01452 d = 20.9 min = 1254s, seen in optical photometry, optical spectroscopy and X-rays.

  HJD = 2444782.9168 + 0.014519035E + 7.002x10^(-13)E^2 - 1.556x10^(-18)E^3

  (Erratum to Patterson et al 1998b) works for 1981-1987. However, given the erratic history of this system, a continuing monitoring would be prudent.
• Others: spin-orbit and 2spin-orbit seen in X-rays; spin-orbit and possibly spin+orbit seen in optical photometry.

Inclination:

~65 deg? (has grazing eclipse).

Distance:

~400 pc?
