203 nights of UBV APT data are reported for R Coronae Borealis in the
years 1992 and 1993. An additional 21 nights of photometry from this o
bservatory are also reported, and previously reported visual estimates
are included to sketch the early stages of a deep decline at the end
of the 1993 season. Through most of these two seasons R CrB reached pe
ak brightness and showed well-developed pulsations of 0.25 mag amplitu
de and period 35.3 +/- 0.2 days. To within the observational errors th
ese maintained phase coherence across the two seasons. The deep declin
e began near the minimum phase of pulsation, whereas in 1985 the deep
decline began nearer to the maximum phase of pulsation, casting some d
oubt on the role of pulsation in triggering deep declines.
