    The period should be increased. Length is constant.
    Depth might decrease with wavelength.

Basic Data

    RA = 13:44:22.6, DE = +48:01:43
    Season = April 15
    V = 11.86, B-V = 0.80 (?)
    HJDo = 4218.7594, AXA fit = 4218.7566 (21)
    P = 2.899703 day , AXA fit = 2.90088 (52)
    HJDo = 4218.7594 (6) and P = 2.899703 (54) days (as listed in Schneider's Extrasolar Planets Encyclopaedia)
    HJDo = 4218.75855 (66) and P = 2.8997405 (16) days (as derived from AXA submitted data); or even better: JDo = 4566.72741 (38), P = 2.8997405 (16)
    Depth = 16.0 ± 0.8 mmag (R & C-band), 14 mmag (i-band)
    Length = 2.01 ± 0.04 hr
    Fp = 0.33 ± 0.04, F2 = 0.83 ± 0.08

8512roe2  Note: It's very difficult to observe exoplanet transits with a Dobsonian because of large image rotation.

8317hnx1 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 66 minutes late.

7804vmt1 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).

 
7801gjl1 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]
