  Maciejewski et al. (2010) claim to have detected a possible sinusoidal
variation in the transit timing variations of exoplanet WASP-3b, which is
currently the only known planet orbiting the star WASP-3. According to
Maciejewski's analysis, this signal might be the consequence of gravitational
perturbations caused by a hypothetical second exoplanet in the WASP-3 system. I
report five transit timing measurements from the summer of 2010 which provide
modest support for Maciejewski's proposed sinusoidal signal.
