Recent Observations of Superluminal Sources, objects (Porcas, 1981; Marscher and Broderick, 1982; Phillips and Mutel, 1982; Walker et al., 1982).

Bent Jets and Tailed Radio Galaxies,axies can provide a strong constraint on the average velocity of the plasma flow -- a contraint not possible for straight jets.

Rapid Variability of 3C273 at 300 GHz,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).
