We report the detection of an unidentified gamma-ray source near the Galacticplane by the COMPTEL experiment aboard the Compton Gamma-Ray Observatory. Thesource is detected at a significance level of ~ 7.2 sigma in the energy range1-3 MeV and at ~ 4.6 sigma in the lower 0.75-1 MeV band in the time periodMarch to July 1995. At energies above 3 MeV are only marginal hints or upperlimits obtained. The MeV spectrum has a soft shape. Strong flux variability isfound within one year at energies below 3 MeV. Possible counterparts ofgalactic and extragalactic nature are discussed.Comment: 7 pages including 5 figures, accepted for publication in A&
