PERIODIC COMET WILD 3 (1994b)
     J. V. Scotti and T. Gehrels, Lunar and Planetary Laboratory,
report that they have recovered this comet with the 0.9-m Spacewatch
Telescope at Kitt Peak, as shown below.  On Feb. 10, there was a
coma 12" across and tail 0'.29 long in p.a. 292 deg (m2 = 22.3).
The indicated correction to the prediction on MPC 18258 (ephemeris
on MPC 23139) is Delta(T) = +0.03 day.

A0535+26
     R. B. Wilson and B. A. Harmon, Marshall Space Flight Center,
NASA; and M. H. Finger, Computer Sciences Corporation, report for
the Compton Gamma Ray Observatory BATSE team:  "The outburst
reported on IAUC 5931 has continued and intensified through Feb. 8.
The daily phase-averaged pulsed intensity in the band 20-40 keV,
relative to the total Crab Nebula flux (pulsed + steady), was 0.2,
0.5, 0.7, 0.8, 0.9, and 1.1 on Feb. 3-8.  The daily total intensity
(also 20-40 keV), measured using Earth occultation, was 0.4, 0.9,
1.4, 1.9, 2.2, and 2.7 relative to the total Crab Nebula flux.  All
values stated above are accurate to +/- 5 percent.  The source is
detectable to at least 100 keV."


SU TAURI
     B. S. Carter, South African Astronomical Observatory, reports:
"Observation of SU Tau by F. Marang on Jan. 29.89 using the 0.75-m
telescope yields magnitudes J = 11.74, H = 9.22, K = 7.14, L =
4.59, which indicates that a dust shell has been ejected."


1994 February 14               (5933)            Daniel W. E. Green
