Astronomical Observations and Instrumentation

We report long‐term UBV observations of 15 bright, active Be stars, namely: X Persei, EW Canis Majoris, θ 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 through the Automatic Photometric Telescope Service in Arizona and through the American Association of Variable Star Observers (AAVSO) photoelectric photometry 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 behavior of some of them. They vary photometrically on timescales ranging from about a day to many years.
