Scientific paper

Near-millimeter radio observations of the stellar object 3C273 that revealed the presence of a flare are analyzed for characteristics of the associated jet. The data were taken at Kitt Peak in early 1983, and displayed a growth in the near-millimeter range compared to data taken during the previous two years. Subsequent near-IR measurements quantified the flux between 1 mm and 1 micron as being on the order of 4 x 10 to the -13th W/sq m, with a luminosity of 3 x 10 to the 12th solar luminosities. The data indicate the emissions arise from a variable relativistic beam with a source within 0.1 pc from the center of 3C273.
