Basic data

    RA = 06:30:32.8, DE = +29:40:20
    Season = December 30
    V = 11.69, B = 12.11, (B-V=0.42), I = 11.03, J = 10.48, K = 10.19
    HJDo = 4508.9761 (2) and P = 1.091423 (3) days (as listed in Schneider's Extrasolar Planets Encyclopaedia, HJDo corrected from earlier value)
    HJDo = 4508.97603 (38) and P = 1.091426 (3) days (as derived from AXA submitted data)
    D = 17.2 ± 1.3 (R & C-band), Depth = 16.5 ± 0.6 mmag (z-band )
    Length = 2.92 ± 0.02 hr (z-band & C-band)
    Fp = 0.24 ± 0.07, F2 = 0.89 ± 0.12

Light curve in discovery paper (Hebb et al, 2008). My reading for the z-band LC:

9120OYE1

 
9101HVP1 If HJDo = 4506.9761 (2) and P = 1.091423 (3) were correct then there should have been a transit with mid-transit time at -0.20 +/- 0.02 hr on this time scale.  Since no such transit was observed there must be an error in HJDo = 4506.9761. I suggest that the discovery paper has a misprint such that HJDo = 4506.7961 instead of 4506.9761.
