- Description:
- Photoelectric measurements of light-changes in the comet Arend-Roland were made from April 22nd to May 6th 1957. From the measurements the absolute magnitude of the comet for the spectral range of 4000 A, m0 = 6.73. n = 3.48 was established. The curve of the light-changes was compared with the incidence of chromospherical flares in this period. Traces of a possible connection of the alterations in the comet´s brightness with changes in the solar activity were recorded.
