1 Schmeer, Patrick Discovered on 1866 May 12 by John Birmingham. First nova to be identified with an existing star (BD +262765, 9.5 mag). Second known eruption detected independently by Norman F. H. Knight (1946 Feb. 9.25 UT) and Armin Joseph Deutsch (Feb. 9.35 UT). Gaia DR2 parallax 1.2127 0.0488 mas (distance 806 33 pc).
2 Otero, Sebastian Alberto Amplitude for ELL variations 0.45 mag. GCVS outburst cycle 29,000 days.
3 GCVS Team VB? A (B <= 12m, 0.2"). SB (P = 227.6d). The spectral period is present in the photometric data of 1891 - 1917 and 1960 - 1971 [J.Bailey, JBAA 85, N3, 217, 1975.]. The epoch of the first outburst JD2402734 (1866). Two smaller outbursts were observed in UV light, JD2438030 (1963) and 2442543 (1975) [L.H.Palmer, J.L.Africano, IBVS N2069, 1982.].
