COMET BENNETT (1974h)
     Mr. J. C. Bennett, Pretoria, provides the following total
magnitude estimates, obtained with a 12-cm telescope: Nov. 13.1 UT, 9;
14.1, 8.5; 15.1, 8.3; 18.1, > 10; 22.1, > 11 (not found).  The
following ephemeris continues that on IAUC 2725.  There are no known
observations after Nov. 25, so the magnitudes are uncertain.

PERIODIC COMET HONDA-MRKOS-PAJDUSAKOVA (1974f)
     Mr. T. Seki, Kochi Observatory, Geisei Station, provides the
following precise position.  The comet is very diffuse, without
condensation.  The magnitude estimate is with a 40-cm reflector, 57 x.
