GCVS NOTE result

In August 1975, before the very rapid increase of light, the brightness of the Nova gradually increased from 17.6m to 13.5m B (JD2442632 - 653.2). After Max almost monotonous decay of brightness is superimposed by "light variations with the amplitude of 0.03m - 1.0m V the period of these variations in the interval JD2442656 - 43100 changed in the range 0.1415d [09167, 09168] - 0.137d [09169, 09170]. Since JD2443100 Min = 2443696.4827 + 0.1396133d*E. Some investigators (see, for instance, [09173]) adopt double value of this peiod. A month after the light maximum of the Nova the radio emission was registered at 2695 and 8085 MHz [09171].
