Survey of the optical variability of compact extragalactic objects. III. Objects from 23h to 11h.
Abstract
This paper reports observations made at Asiago Observatory up to 1977 of the optical variability of 34 quasi-stellar objects located from 23 to 11 hours right ascension. For 14 of them, observed on at least 12 plates, there is no sign of variations larger than 0.3 mag; their redshifts are uniformly distributed from 0.3 to 2.1.
