Description:
Photometry covering 100 nights during 1979 July-November is reported, in an unfiltered band (effectively 5200-8000 A), in a V band, and with a few measures in B. Correlation with the 13 day period of Crampton, Cowley, and Hutchings is found in the form of a double-peaked light curve. A more tentative connection with the 164 day 'precession' period suggested by a broad light minimum near a critical phase in the long cycle is found.
