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, ) 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 .
