Abstract: The blazar PKS 2155-304 has been heavily monitored for over two decades from the optical to gamma rays. The object is highly variable at all wavelengths and has changed by up to 0.75 magnitudes over long-term periods. This paper discusses an eleven night period during which PKS 2155-304 was heavily monitored with the 0.9-meter telescope at Cerro Tololo Interamerican Observatory. During this time period, PKS 2155-304 varied by as much as 0.3 magnitudes in R. The most rapid variation was seen during a three hour period with an increase in brightness of 0.015 mag/hr.
