Circular No. 2893 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION Postal Address: Central Bureau for Astronomical Telegrams Smithsonian Astrophysical Observatory, Cambridge, MA 02138, U.S.A. Cable Address: SATELLITES, NEWYORK Western Union: RAPID SATELLITE CAMBMASS SUPERNOVA IN NGC 1325 J. Dunlap and Y. Dunlap, Corralitos Observatory, Northwestern University, report the discovery of a supernova in NGC 1325, 53" east and 77" north of the nucleus. On Dec. 30.1597 UT, mpv = 14.6. FAST-MOVING OBJECT KOWAL C. Kowal, Hale Observatories, reports the discovery of a fast-moving asteroidal object on plates taken at Palomar, as follows: 1975 UT R. A. (1950) Decl. Mag. Dec. 27.29722 6 58.8 +65 33 12 28.28542 4 26.5 +79 17 29.11319 0 38.0 +79 43 30.11181 22 42.5 +74 10 13 Computations by B. G. Marsden suggest that this may be an Apollo asteroid near aphelion; an approximate ephemeris follows. K. Aksnes finds that the object is probably not in geocentric orbit. 1975/76 ET R. A. (1950) Decl. Delta r Mag. Dec. 30 22 50.1 +74 46.7 0.041 0.995 12.7 Jan. 1 21 48.37 +65 52.1 3 21 30.61 +60 40.5 0.075 0.986 14.3 5 21 22.29 +57 24.5 7 21 17.43 +55 10.7 0.110 0.975 15.3 9 21 14.20 +53 33.1 11 21 11.85 +52 18.1 0.146 0.964 15.9 FAST-MOVING OBJECT WROBLEWSKI C. Torres, Department of Astronomy, University of Chile, informs us that the sign of the declination of this object (cf. IAUC 2891) should be changed. Computations by B. G. Marsden suggest that this is also an Apollo object. However, it is not clear whether the object would now be near the position R.A. = 6h.0, Decl. = +17o, having daily motion 10' north-northwest and magnitude 15; or (having passed by the earth) near the position R.A. = 20h.7, Decl. = +36o, moving some 2o daily south and west and of magnitude about 12. 1975 December 31 (2893) Brian G. Marsden
