1 Schmeer, Patrick Discovered photographically in 1904 at the Royal Observatory, Greenwich, in the course of the work for the Astrographic Catalogue under Henry Park Hollis's direction (1904MNRAS..64..837). Gaia DR2 parallax 4.4369 0.0403 mas (distance 225.4 2.0 pc); proper motion pmRA= -9.003 0.054, pmDE= -19.078 0.057 mas/yr (21.1 mas/yr at p.a. 205.3).
2 GCVS Team SB2. Lower conjunction of the G component T = 2438470.841 + 0.289840d*E [R.P.Kraft, W.Krzeminski, G.S.Mumford, ApJ 158, 589, 1969.]. Outside outbursts the light curve is modulated with spectroscopic elements and has a shoulder at the phase 0.88P and a broad, shallow dip at the phase 0.15P. Outside maxima flickering up to 0.5m with P ~ 16s - 18s is observed. During maxima brightness fluctuations are small [R.P.Kraft, W.Krzeminski, G.S.Mumford, ApJ 158, 589, 1969., E.L.Robinson, ApJ 180, 121, 1973.].
