Volume 21 number 2 (1992)
(Abstract only) HD 187299 (G5I + B7(?)V) was recently proposed as a possible eclipsing zeta Aurigae binary system, on the basis of previous spectroscopic observations. The star was observed photoelectrically in B and V at the University of Toronto and at MacLean Observatory for two weeks around the predicted time of conjunction(1992 June 4), but no eclipse deeper than 0.02 in V or 0.04 in B, lasting more than one day, was observed. The mean V magnitude (7.06) and other measures of V in the literature show a scatter of about 0.2, however, which suggests that one of the stars in the system may be an intrinsic variable. The G5I component is the most likely candidate, since yellow supergiants are often pulsating variables. HD 187299 has therefore been added to the AAVSO photoelectric photometry program.
