1988AJ.....96.1215P LONG-TERM OPTICAL BEHAVIOR OF 144 COMPACT EXTRAGALACTIC OBJECTS: 1969-1988 ANDREW J. PICA, ALEX G. SMITH, JAMES R. WEBB, ROBERT J. LEACOCK, SANDRA CLEMENTS AND PAUL P. GOMBOLA Rosemary Hill Observatory, Department of Astronomy, University of Florida, Gainesville, Florida 32611 Received 18 April 1988;revised 16 June 1988 ABSTRACT Photometric data are reported for 144 extragalactic sources observed during a 19 yr program of photographic monitoring. An additional 22 objects that were classified as optically violent variables (OVVs) have been discussed by Webb et al. (1988). The present paper summarizes results for the generally less active sources not included in that earlier publication. Of these, 92 exhibited optical variations at a confidence level of 95% or more. Light curves are presented for 25 of the more interesting objects, three of which displayed OVV activity in the Florida records; another five sources underwent one or more events that approach the OVV level.
