Abstract

New photoelectric observations at 3 different observatories on 25 nights in 1979, along with examination of older published UBV photometry, reveal no photometric variability larger than 0m.02, thus not confirming the suspicion by visual observers that Rho Bootis is a Cepheid variable with a period of approximately 6 days and an amplitude of approximately 0m.4.
