Position

• Equatorial: 22^h17^m55.38^s, -08^d21^m03.7^s (Gaia)
• Galactic: l=53.00, b=-49.16

Finding Chart:

Patterson & Steiner (1983)

Brigntness:

Optical G=13.9 (Gaia); X-rays: 5.3x10^-11 ergs cm^-2s^-1 (BAT 157m; 14-195 keV), 2.9x10^-11 ergs cm^-2s^-1 (4XMM-DR11)

IP Credential:

***** (Ironclad) Multiple X-ray and optical observations firmly establish the orbital and spin periods of this IP.

Periods:

• Orbital: 0.2020596 d = 4.849430 hr = 17457.95 s, see in optical and X-rays.

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

  (Patterson et al 1998) for the orbital dip.
• Spin: 0.014519035 d = 20.907410 min = 1254.4446 s, 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 1998) 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:

531.5 (522.9-538.3) pc (Gaia EDR3; parallax: 1.842+/-0.028 mas)
