GRB 930131
     J. Ryan, M. Kippen, and M. Varendorff, University of New
Hampshire, report on behalf of the Compton Telescope (COMPTEL)/Compton
Observatory Team:  "The COMPTEL team has imaged a gamma-ray burst
at energies > 0.72 MeV that took place on Jan. 31.78971 UT.  This
event was recorded by the BATSE experiment and was noted as being
one of the most intense bursts yet observed by BATSE.  The burst
exhibited two short peaks in intensity, spanning a period of just
over 1 s.  The COMPTEL analysis (which incorporated a total of 41
events) has resulted in a 1-sigma source location error box whose
corners are located at the following positions (equinox J2000.0):
R.A. = 12h13m.0, Decl. = -7 33'; 12h23m.0, -7 37'; 12h22m.6,
-10 26'; 12h12m.6, -10 19'.  This error box is roughly 3 deg on a
side and is centered at R.A. = 12h17m.8, Decl. = -8 59'.  We are
soliciting collaborators to observe the region with large field-of-
view or rastering instruments in an effort to identify a counterpart
at other wavelengths.  The effort is being coordinated by B.
McNamara at New Mexico State University (bmcnamar@nmsu.edu;
telephone 505-646-2614) and J. Ryan (jryan@unh.edu; 603-862-3510)."
