I am pleased to report my successful observation of WASP-1b, on 2006.10.02 UT from my backyard observatory in Knoxville, TN (USA). This is a newly discovered exoplanet in the constellation Andromeda orbiting the star GSC 2265: 0107 . The entire event was observed with the run commencing at ~01:50UT to establish a pre-ingress baseline. Observations concluded post egress at ~ 10:15UT with the arrival of cirrus clouds. Observatory operations were carried out autonomously under control of ACP 4.2 as has been described earlier. Conditions throughout the night were excellent and all equipment was operating nominally. A meridian flip was executed automatically by ACP just after time JD2454010.75. A detailed description of the hardware used for this observation can be found here. My LC's time of mid transit agrees very closely with the value published at transitsearch.org

A positive linear trend was noticed in the data.This effect is thought to be due to color differences between the stars used for comparison purposes with the variable star. This offset was constant throughout the night and doesn't change with airmass and is independent of the moon. The C2-C1 plot was used to model this linear trend and it was subsequently removed from the light curve. The original plot ( before detrending ) is shown below. An ensemble comparison of four stars was selected for aperture differential photometry with AIP4Win v. 2.1.10. Post egress observations were also influenced by increasing airmass. Standard deviation for the (V-Ens) comparison remained ~0.003 mag for the course of all observations through post egress with noticeable loss of precision occuring at the end of the run with the arrival of cirrus clouds.
