SUPERNOVA ON NGC 2968-2970 BRIDGE
     Dr. M. Schurer, Astronomical Institute, Berne, cables that a
supernova has been discovered by Paul Wild 120" east and 75" north
of the nucleus of NGC 2968, on the luminous bridge from that galaxy
to NGC 2970.  On Oct. 31.14 UT the photographic magnitude was
15.5.


PSR 2020+29
     A cable from the Laboratono Nazionale di Radioastronomia,
Bologna, reports the discovery of a pulsar at R. A. = 20h20m32s +/- 2s,
Decl. = +29o +/- 0o.5 (equinox 1950.0) using the east-west arm of the
Bologna northern cross at 408 MHz.  The pulse period is 0s.344, and
there are components within individual pulses of half-power width
less than 5 ms.  The pulsar is interesting as it lies only one
degree from the pulsar AP 2015+28.


COMET SUZUKI-SATO-SEKI (1970m)
     The following ephemeris is a continuation to that on IAUC 2284
(in spite of the error in Incl.).  Recent observations suggest that
the comet will be a few minutes of arc east and north of these
positions.
