Photoelectric Observations of Nova Her 1963

No. 60
Budapest, 1966

Abstract

Nova Herculis 1963, discovered on Febr. 6 1963 by E. Dahlgren, was observed photoelectrically in three colours from Febr. 9 1963 to Oct. 2 1964 at the Konkoly Observatory. Magnitudes, reduced to a single comparison star and one photometric system, were compared with other photoelectric observations taken from the literature. The plotting of a composite light curve proved to be possible, at least in the first three months. Rapid fluctuations in brightness and colour have been suspected already in 1964 and confirmed later by photoelectric observations at the Asiago Observatory. Breaks discovered on the colour-index and on the logarithmic light curves were confronted with spectroscopic results.
