                                ABSTRACT

In three years of operation, COMPTEL has measured the locations (mean 
accuracy ~1 deg) and spectra (0.75-30 MeV) of 18 gamma-ray bursts and 
continues to observe new events every 1-2 months.  The existing COMPTEL
bursts have been analyzed as a group to study the small-scale angular 
distribution and MeV emission properties.  Furthermore, measurements of 
individual strong bursts like GRB 930131 and GRB 940217 provide unique 
insight into the physics of burst sources.  We review recent analyses 
of COMPTEL burst locations and spectra and give an update on recent 
observations, including the on-going search for fading low-energy 
counterparts using rapidly-determined COMPTEL burst locations.
