Period needs to be adjusted.
Most R-band depths are greater than the FLWO 1.2 m z-band depth.
Note: There's a flare star ~6.7 'arc east of WASP-1, so be sure to check to make sure it's not flaring before using. A fuller description of this star is at flare.
RA = 00:20:40, Decl = +31:59:24
Season = October 10
B=12.19, V = 11.65, R = 11.33, I = 11.02, B-V = 0.54, V-I = 0.63 (based on JK)
HJDo = 3151.486 (6) & P = 2.51997 (16) day (Schneider listing in Extrasolar Planets Encyclopaedia)
HJDo = 3151.4885 (19) & P = 2.5199480 (15) day (AXA fit); or better yet: HJDo = 4411.46406 (45) & 2.5199480 (15)
Depth = 14.5 ± 0.8 mmag (13 mmag z-band)
Length = 3.65 ± 0.08 hr
Fp = 0.20 ± 0.03, F2 = 0.86 ± 0.10

Good first WASP-1 observation.
Note, Star #9 is a flare star (0.2 mag) so don't use it for reference.
