Abstract

Interstellar scintillation was detected from a source in or near the supernova remnant G78.1 + 1.8, implying an angular size ≲10−6 arc s, a brightness temperature >1018 K, and a distance of ∼3 kpc. The source does not seem to be a pulsar and is therefore the first source other than a pulsar to show interstellar scintillation. We place limits on the scintillating flux for 15 other galactic and extragalactic objects.
