Abstract
Photoelectric observations of the R Coronae Borealis (R CrB) star V854 Cen (NSV 6708), obtained during 1989-91, are presented. These observations cover a number of declines of this highly variable star and provide an opportunity to study the diverse nature of these events for an individual R CrB star. The time-gaps, between declines observed from 1987 to 1991, are integer multiples of 43.2 d, which is a periodicity identified as a likely pulsation mode of the star. The phase of the cycle at which the onset of the decline appears to occur is near that of maximum light
