1 Schmeer, Patrick Gaia DR2 parallax 1.12 ± 0.14 mas (distance 0.9 ± 0.1 kpc).
2 GCVS Team Nova Sge 1783 (Max JD2372494:). Min I = 2445137.8993 + 0.1536342d*E; D = 0.16P. Brightness outside eclipses is usually ~18.7m, the depth of the eclipses is ~ 1.5 - 2m. At present outbursts by 1.6m are sometimes observed similar to the UG type variable outbursts, as well as rapid flickering of light [M.M.Shara, A.F.J.Moffat, J.T. Graw, D.S.Dearborn, H.E.Bond, E.Kemper, L.Lamontagne, ApJ 282, 763, 1984.].
