4U 0115+634
     R. B. Wilson, M. H. Finger, and D. M. Scott report for the
Compton Gamma Ray Observatory BATSE pulsar team: "The outburst from
the x-ray binary pulsar 4U 0115+634 previously reported on IAUC
5990 continues as of May 30.  The flux in the energy band 20-50 keV
rose at a constant rate from the onset of detection on May 8 to
about 65 mCrab on May 18, increased at a lesser rate to about 75
mCrab on May 28, then increased more rapidly, reaching about 180
mCrab on May 30."


PERIODIC COMET SHOEMAKER-LEVY 9 (1993e)
     D. Jewitt and N. Trentham, University of Hawaii, communicate:
"New observations from the University of Hawaii 2.2-m telescope
show that nucleus 15 (= G) is double.  On May 7 UT, the fainter
component (15b) appears 3".5 east and 3".7 north of the brighter
(15a).  The red magnitude difference measured in a 1"-radius
aperture is 3.8.  The fainter component is not evident in
observations taken in previous months under similar observing
conditions."


SUPERNOVA 1994I IN NGC 5194
     L. V. Morrison and R. W. Argyle, Royal Greenwich Observatory,
report the following V magnitudes, derived from the observations
mentioned on IAUC 5989 (the accuracy ranges from +/-0.10 mag at V =
13.0 to +/-0.20 at 14.0):  Apr. 11.06 UT, 12.93; 12.06, 12.90;
13.05, 13.12; 14.05, 13.10; 15.05, 13.27; 16.04, 13.33; 23.03,
13.98; 25.02, 13.88.
