POSSIBLE SUPERNOVA IN NGC 4902
     J. Maza, Department of Astronomy, University of Chile, reports
the discovery by M. Wischnjewsky of a possible supernova on a plate
of NGC 4902 exposed by him.  The object is 6" west and 60" north of
the galaxy's nucleus and was of photographic magnitude 16 on Aug.
19.020 UT.


COMET KOWAL (1979h)
     C. T. Kowal, Hale Observatories, reports that he has discovered
a comet as follows:

     1979 UT          R. A. (1950) Decl.            m1
     July 24.21042   19 25.5     -17 48             19
          25.20903   19 25.0     -17 50             19
          27.22014   19 23.9     -17 55             19

The object is diffuse with neither condensation nor tail.


PERIODIC COMET SCHWASSMANN-WACHMANN 3 (1979g)
     D. A. Pickup, Royal Observatory, Edinburgh, telexes the following
precise position, obtained by S. B. Tritton with the 1.2-m
U.K. Schmidt telescope at Siding Spring:

     1979 UT             R. A. (1950) Decl.          m1
     Aug. 22.38293    13 06 08.85   - 7 31 21.0    13-14


SS 433
     J. Faulkner, R. L. Gilliland and E. Kemper, Lick Observatory,
write: "151 15s scans taken on July 17 with our 3-m telescope IDS
system show 'stationary' H-alpha emission with radial velocity 318 +/- 15
km/s.  Longer scans by Faber on July 4-5 agree.  If P ~ 13d.0 (IAUC
3388), these observations are near maximum positive velocity; allowing
for ~ 20 km/s systematic shift between H-beta and H-alpha, they agree
well with the Dominion Astrophysical Observatory H-beta velocity of
296 km/s on July 16 (Cowley, private communication).  Polarimetric
spectra (Miller and Schmidt, May 5) show a significantly smaller
velocity.  A smaller periodic term in our data (K1 = 5.2 +/- 1.0
km/s, P = 0d.002776 +/- 0d.000003) may be instrumental in origin."


1979 August 27                 (3395)              Brian G. Marsden
