Abstract (from CDS):

We report on 1.6GHz Very-Long-Baseline-Interferometry (VLBI) observations of supernova SN1979C made on 18 November 2002. We derive a model-dependent supernova size. We also present a reanalysis of VLBI observations made by us on June 1999 and by other authors on February 2005. We conclude that, contrary to our earlier claim of strong deceleration in the expansion, SN1979C has been undergoing almost-free expansion (m=0.91±0.09; R∝tm) for over 25 years.
