                              COMET AND NOVA SECTION

COMET RUDNICKI (1966e)

This new comet was discovered on October 15 by Dr. Konrad Rudnicki, California Insti-
tute of Technology. At the time, it was a centrally condensed object with a 1' tail
at magnitude 13.5. In December, it may be seen in the south-west during the
evenings. It should be visible with small telescopes and possibly with binoculars.
The following ephemeris was taken from IAU Circular 1981:
