Scientific paper

Thirty-three extragalactic variable radio sources have been observed at 90 GHz (3.3 mm) over two several-day-long periods in a search for daily and hourly variations. OV-236 (1921-29) showed a decrease in flux density by a factor of 2.7 over a three-day interval, recovering its previous flux density two days later. (OV-236 began a dramatic outburst a few months later.) The other sources exhibited no significant variations approximately > 20%. A summary of previous radio observations of rapid variability is contained in the appendix.
