We have found a 2.09 h modulation in brightness of the dwarf nova GW Lib.
This bears no special relationship to the 1.28 h spectroscopic period that is
believed to be the orbital period. It was present in May 2001, but not in
observations made in 1997 and 1998 and is of unknown origin. Similar
unexplained periodicities are present in FS Aur and V2051 Oph.
