Abstract The AAVSO compiled 10,560 CCD observations of the suspected exoplanet
transit object TrES-1b covering seven complete transit windows, three windows
of partial coverage, and coverage of baseline non-transit periods. Visual
inspection of the light curves reveals the presence of slight humps at the
egress points of some transits. A boot strap Monte Carlo simulation was applied
to the data to confirm that the humps exist to a statistically significant
degree. However, it does not rule out systemic effects which will be tested
with campaigns in the 2005 observing season.
