TWX 710-320-6842 ASTROGRAM CAM Telephone 617-864-5758 POSSIBLE NOVAE W. Liller, Vina del Mar, Chile, reports his discovery of a possible nova in Norma at R.A. = 16h09m51s0, Decl. = -53deg11'32" (equinox 1950.0). The object was detected at mag 9.4 on Sept. 19.00 UT but must have been fainter than mag 11.5 on Sept. 10.0. E. P. Aksenov, Sternberg Astronomical Institute, reports that N. E. Kurochkin has discovered a possible nova in Triangulum at R.A. = 2h42m2, Decl. = +33deg19' (equinox 1950.0). The object was observed at mpg = 15.0 on Sept. 11.96 UT. OCCULTATION OF 14 PISCIUM BY (51) NEMAUSA A preliminary report by D. W. Dunham, Computer Sciences Corporation, indicates that extensive positive and meaningful negative observations of this Sept. 11 event were made throughout the southeastern United States. The northern limit was effectively defined by M. Croom, who observed a 2s3 occultation at Yorktown, VA. The longest reported chord, 13s5, by R. Melvin in central North Carolina, corresponds to a diameter of 160 km for Nemausa. The southernmost positive observation, by E. Seykora and others at Greenville, NC, gave an 8s2 occultation. A few observers reported secondary extinctions, but these are believed to be due to seeing or transparency variations or photoelectric guiding errors.
