TWX 710-320-6842 ASTROGRAM CAM Telephone 617-495-7244/7440/7444 MARSDEN or GREEN@CFA.BITNET MARSDEN or GREEN@CFAPS2.SPAN AS 296 R. H. McNaught, Siding Spring Observatory, reports that this star appears in outburst on Atlas Stellarum, 1968 July 27, at magnitude B = 12.9. Examination of Schmidt survey films from 1984-86 gives evidence of only slight variability around minimum. Patrol photographs by McNaught in 1986-87 yield a minimum magnitude of V qbout 11.8. Estimates from recent patrol photographs are 1988 May 21.59 UT, 11.5:; June 12.67, 10.4; 13.70, 10.4; 23.76, 10.0; 24.72, 10.0; July 11.59, 10.0. Visual magnitude estimates: July 10.02 UT, 10.1 (P. Schmeer, Bischmisheim, W. Germany); 11.00, 10.0 (Schmeer); 12.5, 10.0 (P. Williams, Heathcote, N.S.W.); 13.5, 10.0 (A. Pearce, Woodlands, W. Australia).
