Scientific paper

Results of repeated VLA (Very Large Array) observations of the inner 600 pc 'starburst' region of M82 at 5 and 15 GHz at 0.3 inch resolution are presented. A histogram of the fractional flux changes of the brightest ten sources over a ten and a half year period is presented which shows that the degree of variability is very different among the brightest sources. A histogram showing the distribution of the spectral index between 5 and 15 GHz is also presented. A map of the compact nuclear sources in M82 at 15 GHz, with combined A and B array data, is given.
