Scientific paper

We present preliminary results from a total of 212.1 hours of data from multi-site observations of GW Lib. Our results reveal a signal near the 2.1-hr period previously detected by Woudt & Warner in quiescense, but of slightly shorter period, and also a modulation at ∼4-hr. Both the 2 and 4-hr modulations appear to vary in period and/or phase. The 4-hr period may be the fundamental period and the 2-hr period a harmonic. Fourier analysis also shows a transient ∼20-min modulation that is anti-correlated in amplitude with the ∼2-hr periodicity. Using a smaller data set, we investigate higher frequency pulsations and compare to those found by previous authors before outburst.
