Photoelectric monitoring of a shell star in perseus

We report on the 3-colour photoelectric monitoring of the shell star in Perseus, discovered in 1978, 1]. On the night of 1983 Feb 4–5, this star still showed obvious light variations, though the amplitude was less than in 1979. On the next night, the light variation was close to the observing error. We surmise that the shell activity is now at a stable phase for a few years.
