RY SAGITTARII
     M. W. Feast, South African Astronomical Observatory, relays a
report from J. Hers, President of IAU Commission 6, that R. W.
Fleet, of Salisbury, Zimbabwe, observed this R CrB-type variable at
mv = 7.8 on Jan. 31 and Feb. 1.  This may indicate the start of a
fade.  An observation by Vincent, Salisbury, on 1981 Dec. 15 showed
the star at mv = 6.5.


ERUPTIVE VARIABLE IN THE LARGE MAGELLANIC CLOUD
     J. Maza, Department of Astronomy, University of Chile, telexes
that M. Wischnjewsky has found an eruptive variable in the bar of
the Large Magellanic Cloud as follows:

     1982 UT             R. A. (1950) Decl.        mpg
     Jan. 22           5 21 44.29   -70 13 53.6    14

The object was at mpg = 15 on 1981 Dec. 28, mpg = 14 on 1982 Jan. 29.


PROBABLE COMET
     R. D. Eberst, Royal Observatory, Edinburgh, writes that Susan
B. Tritton has found another comet on the J atlas (observed with
the U.K. l.2-m Schmidt at Siding Spring) of the ESO/SRC Southern
Sky Survey.  His accurate measurements of the trail ends yield:

     1978 UT             R. A. (1950) Decl.        m1
     Mar.  5.6034     11 55 41.28   -30 30 13.9    17
           5.6520     11 55 38.89   -30 30 06.6

There exists a possibility that the motion should be reversed.


COMET BOWELL (1980b)
     S. M. Larson, Lunar and Planetary Laboratory, reports that his
observations of this comet on Jan. 31 with the l.5-m reflector
showed moderate CN emission.  The comet is currently at r = 3.39 AU.
For an ephemeris see MPC 6214.


1982 February 5                (3662)              Brian G. Marsden
