The blazar PG 0735+178 was monitored for more than 20 nights for microvariability on multiple timescales. We present this data which shows variations of amplitude several hundredths to several tenths of a magnitude on timescales of hours to days. The object also has exhibited variations with an amplitude as large as 2 magnitudes on the timescale of years. This microvariability will be investigated as a function of outburst and quiescent states of the object over the course of these timescales. These variations place severe limits on the size of the emitting region, and provide constraints for the physical processes responsible for these variations. JPM and HRM are grateful for support of a grant from the Research Corporation and the PEGA-RPE program at Georgia State University.
