Abstract
We report long-term UBV observations of 15 bright, active Be stars, namely: X Persei, EW Canis Majoris, theta Coronae Borealis, 4 (V839) Herculis, 88 (V744) Herculis, 66 (V2048) Ophiuchi, NW Serpentis, CX Draconis, 12 (V395) Vulpeculae, 28 (V1624) Cygni, QR Vulpeculae, 59 (V832) Cygni, EW Lacertae, o Andromedae, and KX Andromedae. The observations were made in 1996-1999 th rough the Automatic Photometric Telescope Service in Arizona and through th e American Association of Variable Star Observers (AAVSO) photoelectric pho tometry program and have been added to a database extending back 20 years. We describe the stars' recent behavior and also comment on the long-term be havior of some of them. They vary photometrically on timescales ranging fro m about a day to many years.
