Each file contains one night's observations, with the HJD, airmass, and extinction-corrected instrumental differential magnitudes. Observations were made from Running Springs, CA, USA (elev. 1870m), using a 35cm Schmidt-Cassegrain telescope and Optec SSP-3 photodiode photometer. Comparison star was 47 (k) Bootis. Observations were in Johnson B and V bands, with the exception of 16 June 1990, which was in V only. The data includes 14 records of 8 separate eclipses, including one essentially complete light curve in B and V taken 06 May 1990. Robert A. Jones Running Springs Observatory P.O.
