Butterworth, for BACODINE/GCN,\nreport the following:\n\nCGRO-COMPTEL observed GRB 990123 to be extremely bright in its ~MeV energy\nrange.  The >0.7 MeV emission rose about 18 seconds after the initial BATSE \ntrigger at 9h 46m 56.12s U.T. and lasted about 46 seconds, for a 10 sigma\ndetection, despite its very large zenith angle (59 degrees).  An initial \ndetection notice was sent about 10 minutes after burst onset.  Improved\nskymaps and light-curves for the full 0.2-30 MeV range have now been posted\nat the CGRO-COMPTEL Rapid Burst Response web-site:\n\n     http://wwwgro.unh.edu/bursts \n\nThese are still considered preliminary as our standard energy calibration is\nnot yet complete.\n\nThis message can be cited.",
