Liller, Vina del Mar, Chile, reported his discovery of a possible nova at R.A. = 18h05m44s6, Decl. = -26deg16'44" (equinox 1950.0, uncertainty 10"). Orange-filter magnitudes were: Nov. 2.02 UT, 10.7; 5.04, 10.6. An objective-prism red photograph showed continuum and possible weak emission at H-alpha. Confirmation from other observatories is not yet available. 1985 November 12 (4135) Brian G. Marsden
