Be Stars in the AAVSO Photoelectric Photometry Program
We present light curves, and an analysis of periodicity, for the threeBe stars in the AAVSO Photoelectric Photometry Program for which thereare adequate data. V2048 Ophiuchi was variable by 0.2 magnitude beforeJD 2447900, but has been constant, at minimum, since. V832 Cygni hasvaried quasi-cyclically by 0.1 magnitude over the period of observation.EW Lacertae showed a broad minimum, 0.2 magnitude deep. The spacing ofthe observations is not well suited for investigating the short-termvariations of these stars.
| Walraven photometry of nearby southern OB associations
Homogeneous Walraven (VBLUW) photometry is presented for 5260 stars inthe regions of five nearby southern OB associations: Scorpio Centaurus(Sco OB2), Orion OB1, Canis Major OB1, Monoceros OB1, and Scutum OB2.Derived V and (B - V) in the Johnson system are included.
