  • 1. California Univ., Santa Cruz (USA). Lick Observatory

Description

Spectroscopic and photometric observations are reported which show that the images of the double quasar 0957 + 561 A, B are variable. Brightness changes were observed to be accompanied by corresponding spectral variations. These data suggest that the quasar itself is an intrinsically variable object. (U.K.)
