It was measured on two nights only, with the following results: 23 41 47.2 +57 30 59 -1 -2 2 17.069 0.042 0.983 0.088 The magnitudes and colours for four stars were remeasured by A. Henden using PSF photometry to isolate each star's light from fainter companions, often only 3-6 arcsec distant. The stars remeasured were ID's 2, 4, 9 and 10. An AAVSO Preliminary "e" chart dated 8/1994, has the following magnitudes, based on Brian Skiff's photometry (IBVS 3983) plus three Pv measures. Additionally there is some PEP(V) photometry from M. Kidger, TA E-Circ. 814. ID Henden AAVSO Kidger 1 13.033 13.1 2 13.328 13.3 4 13.943 14.1 13.95 6 14.510 14.4 7 14.656 14.8 14.65 10 15.031 15.03 Bruce Sumner Revised 30June 1999
