omicron ANDROMEDAE
     P. Koubsky, Ondrejov Observatory, reports that observations
with the coude spectrograph on the 200-cm reflector (dispersion 8
A/mm) show that the shell was less pronounced on Dec. 18.86 UT than
on Nov. 26.69.  This is contrary to the suggestion on IAUC 2881 and
possibly indicative of short-term variations in the shell spectrum.


COMET BRADFIELD (1975p)
     J. Hers, Randburg, sends the following precise positions:

     1975 UT             R. A. (1950) Decl.
     Nov. 30.06875    14 00 24.26   -49 05 26.7

     Total visual magnitude estimates by M. V. Jones, Maryborough,
Queensland (30-cm reflector): Nov. 28.74 UT, 8.3; 30.71, 8.0:.


COMET SATO (1975q)
     The following precise positions were obtained by H. L. Giclas
at the Lowell Observatory.  Measurer: M. L. Kantz.
