A significant fraction of papers on this LLIP calls it YY Dra. See this page for the history and the current status of the controversy over these names.

Position:

• Equatorial: 11^h43^m38.54^s, +71^d41^m20.8^s (Gaia)
• Galactic: l=130.30, b=+44.46

Finding Chart:

  HJD = 2446863.4376(5) + 0.16537398(17) E

  (Haswell et al. 1997) for secondary's inferior conjunction.
• Spin: 0.0061263 d = 8.8218 m = 529.31(2) s
• Others: most X-ray power at 265s (1/2 spin period), 275/550s sidebands in the optical.

Inclination:

42+/-5.

Distance:

194.87 (193.88-195.98) pc (Gaia EDR3; parallax: 3.564+/-0.149 mas)
