Remark:
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]; D = 0.04P. d = 0.02P. There are also rapid light
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.
