SUPERNOVA IN IC 4839
     J. Maza, Department of Astronomy, University of Chile, telexes
that M. Wischnjewsky discovered a supernova of  mpg = 15.0 in
the Sb galaxy IC 4839 (R.A. = 19h11m5, Decl. = -54deg43', equinox 1950.0)
on a plate taken by L. E. Gonzalez at Cerro El Roble on Oct. 22.
On Sept. 25 the object was of mpg ~ 19.  The offset from the
galaxy's nucleus is 22" east, 82" south.


NOVA SAGITTARII 1984
     B. H. Foing, European Southern Observatory, telexes that
image-tube observations with the 1.5-m telescope and Boller and
Chivens spectrograph over 360-700 nm on Oct. 16.03 UT showed wide
Balmer emission lines and emissions of Fe II, N III and O III.

     Visual magnitude estimates by R. McNaught, Coonabarabran,
NSW: Oct. 10.45 UT, 13.1; 11.44, 13.2; 13.44, 13.5; 15.40, 13.5.


PERIODIC COMET SHOEMAKER (1984q)
     Total visual magnitude estimates: Oct. 6.47 UT, 12.0 (C. S.
Morris, near Mt. Wilson, CA, 0.25-m reflector; difficult because
of the moon nearby); 14.8, 11.8 (R. McNaught, Coonabarabran, NSW,
0.32-m reflector); 15.8, 11.8 (McNaught); 16.01, 11.0 (J. Bortle,
Stormville, NY, 0.32-m reflector); 17.03, 11.1 (Bortle).


PERIODIC COMET TAKAMIZAWA (1984j)
     Total visual magnitude estimates: Sept. 18.08 UT, 11.6 (J.
Bortle, Stormville, NY, 0.32-m reflector); 19.25, 11.9 (C. S.
Morris, Tujunga, CA, 0.25-m reflector).


OCCULTATION OF SAO 146599 BY (47) AGLAJA
     P. Maley, Houston, TX, reports that observations by C. Herold
at Long. -94deg43'01"0, Lat. +32deg00'22" 6, near Mt. Enterprise, TX,
indicated a full occultation of duration 1.8 s, beginning at Sept.
16d02h25m30s2 UT.  Dimming began 1.0s earlier, and there was a
blink 0.7 s after reappearance.  Observations by Maley some 8 km
away (Long. -94deg43'49"3, Lat. +31deg56'13"0) showed no occultation.


1984 October 26                (4002)              Brian G. Marsden
