GCVS NOTE result

"Nova Sge 1913, 1946, 1978. VB A (B 15.76m B, 7"", 280deg)." Really it is not a nova. Three outbursts were registered up to day: JD2420094, 32001, 43844 [09710, 09711]. There are superhumps on the light curve during the outburst with 0.057250d >= P >= 0.05714d (A=0.3m V) [09710, 09776]. There are light variations between the outbursts (A = 0.14m - 0.3m). During some of light weakenings Algol-like eclipses are observed (A = 0.2m) with the elements: Min I = 2437547.72845 + 0.0566878455d*E "[09774] oscillations (A <= 0.01m). The periods of these oscillations before the 1978 outburst were 28.98s and 27.87s [09774], but after this outburst - 28.95963s [09775]. According to [09777], in 1976 - 78 these oscillations were represented by the elements: Max = 2443311.790250 + 0.00032254826d*E + 9.8d*10**(-16)*E**2.
