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

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.
