Transit Light Curves










This data has been shifted -1 hour to acommodate what must have been a 1 hour clock error; without this correction mid-transit would have been 67 minutes late.







Good!


Partial transits are useful for investigating the presence of anomalous brightenings after egress (or before ingress) that could be caused by the hot Jupiter having a ring system or dust cloud (i.e., forward scattering).


Valiant effort 3.5 months after the object's "season." Large air mass seems OK. Length & mid-transit are uncertain due to lack of pre-ingress OOT. Depth differs from discovery paper's 14 mmag but the filter bands are at opposite ends of the visible spectrum (IR-blocking versus Sloan i-band). [Based on revised submission, 7903]
