Abstract
With a broadband bolometer mounted on the 3.6 m ESO telescope we have measured 3C273 at 300 GHz 6 times in 6 days. During this series of measurements we observed a sudden drop in flux density by 11.6 ± 2.9 Jy (spectral index assumed to be zero, and all known errors included). In an interpretation with the model of bulk relativistic motion we can combine the brightness temperature inferred with the observed superluminal motion and derive strict limits on the model parameters.
