V1500 Cygni

P. C. Gregory and W. H. McCutcheon, Physics Department, University of British Columbia, report that observations on Dec. 15.75 UT with the Algonquin 46-m radio telescope gave a flux density of 35 +/- 6 mJy at a frequency of 10.5 GHz. P. Tempesti, Collurania Observatory, writes that the amplitude of the short-period variations in the V magnitude (cf. IAUC 2834, 2842) had decreased to 0.03 on Oct. 2. The various observations indicated that the period varied between 0.137 and 0.141 day.
