Comments on LCs on this web page
    "Length" does not appear to be decreasing using only data in the AXA (+0.0 +- 1.0 min/year), which is not compatible with the suggestion by Mislis  & Schmitt (~ 3.16 min in ~ 2 years), reference below.

Basic data - Updated 20090817

    RA = 19:07:14, Decl = +49:18:59
    Season = July 08
    V = 11.41, B-V =
    HJDo = 3957.63492 (13) & P = 2.470614 (10) day (Schneider listing in Extrasolar Planets Encyclopaedia)
    HJDo = 3957.63512 (36) & P = 2.4706099 (6) day (AXA fit); or even better HJDo = 4377.63888 (24) & P = 2.4706099 (6) day (AXA fit)
    Depth = 17.0 ± 0.5 mmag (mostly R-band)
    Length = 1.70 ± 0.05 hr
    Fp = 0.49 ± 0.03, F2 = 0.89 ± 0.07

9727GJP  That's interesting! This & other LC (below) of same event show the same "bump"  before egress. However, the Wiggins LC (same event) doesn't show it.

Same transit as the one below, but different filter.




OOT is well-behaved; good choice of refernce stars.



7901rcr1


Good first submission. Need more OOT, but solution agrees with expection very well.


Nice.




Observer is Isaac Cruz (Ohio), using a clear filter (disregard the axis label). Mid-transit was early (~4 min).


7726rcr1


The model fit treats this data as an ingress only for timing purposes.




Something funny happened near end of obs'g session; otherwise, good fit.


Beautiful!


6926HVP1


Note: I include partial transits for the purpose of searching for anomlaies after egress (or before ingress) that could be produced by forward scattering by a hot Jupiter's ring system or dust cloud. The above Summary Table does not include transit measurements from partial transits.

Out-of-Transit (OOT)


Out of transit observation, after a false start requiring re-acquisition with different flat frame-related offset.
