Scientific paper

The observation of supernova 1986j in NGC891 at lambda 1.2 mm and 3 mm at epoch 1986.8, using the 30 m Millimeter Radio Telescope (MRT), is reported. The spectrum observed is flat or rising towards shorter wavelengths. It lies above the extrapolation of the optically thin synchrotron radio spectrum of SN1986j at centimeter wavelengths at a similar epoch. The MRT observations are interpreted as arising from a pulsar powered synchrotron nebula at the center of the expanding layers of supernova ejecta.
