The light curve of the peculiar symbiotic star HM Sge.
Abstract
The light curve of HM Sge in 1950 - 1986 derived from photographic and photoelectric observations in Crimea is given. Before the outburst the photographic magnitude of the star was ≥17m with possible variations in the range of ≥1m. The amplitude of the outburst is about 7m, the duration of brightness increase is found to be ≤340 days. In the light maximum the variations decreased with the time. The U-B and B-V colour curves after flash are also given. A strong decrease of U-B and B-V colour curves after flash are also given. A strong decrease of the U-B index was revealed in 1983.
