P Cygni in 1987-1993
Abstract
New photoelectric photometry of P Cygni made between 1987 and 1993 is presented. The cycle lengths derived from the light curve are approximately 27 and 220 days, respectively. The approx. 220 day period implies a connection with the observed shell ejections which has an ejection period of about 200 days.
