FAST-MOVING OBJECT HELIN
     E. Helin, California Institute of Technology, reports that she
has discovered a fast-moving asteroidal object on exposures with
the 46-cm Schmidt telescope at Palomar Mountain, as shown below.

PROBABLE NEW SATELLITE OF JUPITER
     Re-reduction of the first three positions on IAUC 2855 gives
the result below.  The basic conclusions concerning the probable
satellite are unchanged.  No new observations have been reported.

     1975 UT             R. A. (1950) Decl.
     Sept. 30.31250    1 17 26.33   + 7 02 52.2

COMET BRADFIELD (1975p)
     Selected total visual magnitude estimates: Jan. 4.02 UT, 7.3
(C. Sherrod, North Little Rock, Arkansas, 15-cm refractor); 4.93,
6.9 (S. O'Meara, Harvard College Observatory, 6-cm finder); 5.02,
7.4 (P. Maley, Houston, Texas, 13-cm refractor); 5.94, 7.2
(O'Meara); 6.01, 7.8 (Sherrod); 7.09, 7.5 (M. J. Mayo and J.
Truxton, Agoura, California, 25-cm reflector); 8.02, 7.6 (Maley).


omicron ANDROMEDAE
     T. Bolton and A. Gulliver, David Dunlap Observatory, report
that observations since Aug. 1975 show the steady development of a
strong shell in the H lines (cf. IAUC 2881, 2889).  The metallic
shell lines are weak and highly variable, observations on 1976 Jan.
4 and 5 showing dramatic changes on timescales as short as 1 day.


1976 January 9                 (2899)              Brian G. Marsden
