Comments on LCs on this web page

    This exoplanet seems well-behaved. The period is stable and a little short.

Basic data - Updates After Each New LC Terminated 2009.07.20 (occasional updates will be made when I have time)
    RA = 17:52:07.0, Decl = +37:32:46
    Season = June 21
    V = 12.40,
B-V = 0.71
    HJDo = 4185.9101 (3) and P = 1.30619 (3) days (as listed in Schneider's Extrasolar Planets Encyclopaedia, HJDo corrected from earlier value)
    HJDo = 4185.91028 (39) and
P = 1.3061867 (7) days (as derived from AXA submitted data); or even better: HJDo = 4632.62614 (21), P = 1.3061867 (7).
    Depth = 27.1
± 0.1 mmag (VRIC-band)
    Length = 1.29
± 0.01 hr
    Fp = 0.61 ± 0.02, F2 = 0.88 ± 0.02

First submitted transit of the 2008 "season" is essentially "on time."



7910jbe1


On time!


7824HVP1


On time! Alto-cumulus drifted through LOS during transit.


They don't get much better than this! Perfect agreement w/ mid-transit time, depth and length.

 
This BB-band (blue-blocking filter) LC shows excellent agreement with R-band measurements made by someone else and also supports the ephemeris period.


Consistent w/ expectation.

Beware of using for reference a 16th mag variable 8.9 'arc to the southeast of TrES-3 (discovered by G. Srdoc) at RA/DE = 17:52:44.79, +37:27:53.6 (outside above image FOV). Also, G. Srdoc identifies a star 2 'arc SW of TrES-3 (GSC 3089:825) as a Delta Scuti. I found that a star 6.4 'arc north (GSC 3089:1273) exhibited a 320 mmag eclipsing binary variation on 2007.08.13, centered at 04.9 UT.
