Abstract

Strong short-lived flares from black-hole candidates have been detected in the hard X-rayregime and possibly also at γ-ray energies. Here we present a search for short-lived flares in the 0.75–30 MeV COMPTEL data. No flares are found during the 5 viewing periods considered, with typical upper limits of a few times the Crab flux.
