Comments on LCs on this web page:

    All 8 LCs are early (~10 min), so period probably needs to be shortened.
    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.

Transit Light Curves





Somewhat affected by monlight, cirrus clouds and variable seeing.


Nice! Also late, & by same amount as Salto's LC 2 weeks earlier.


Nice work, especially for a first submission.

Out-of-Transit (OOT) Light Curves



Good first WASP-1 observation.


Finder Image


Note, Star #9 is a flare star (0.2 mag) so don't use it for reference. (Labeled image courtesy Cindy Foote.)

Flare Star


2007.10.15 flare event for Star#9 in above finder chart (as measured by Bruce Gary in R-band).
