omega ORIONIS
     R. A. Donahue, E. F. Guinan and G. P. McCook, Astronomy
Department, Villanova University, report: "Photoelectric photometry
of the bright Be star omega Ori obtained on Feb. 20 shows an increase
in brightness at 658.5 nm by 0.2 mag and also a substantial
reddening of its color index when compared to data from January.
These photometric changes, and the changes in polarization reported
by Hayes (IAUC 3777), herald a new shell episode for the star."
