Table summary of transit measurements
Comments on LCs on this web page
This exoplanet seems well-behaved. The period
is stable and a little shorter than the nominal value.
Added Carballo LC (2014 Jul 12), which allows
a period refinement: P = 1.30618690(7) days. Depth, length and
shape appear to be the same since 2009.
Basic data -
Updates After Each New LC Terminated
2009.07.20 (occasional updates will be made when I have
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), P = 1.3061867 (7) days (as derived from AXA submitted data); or even better: HJDo = 4632.62614 (21), P = 1.30618690(7) days.
Depth = 27.1 ± 0.1 mmag (VRIC-band)
Length = 1.29 ± 0.01 hr
Fp = 0.61 ± 0.02, F2 = 0.88 ± 0.02

9711SG21 Possible star spot bump after mid-transit is unsupported by LC by Naves (above).
First submitted transit of the 2008 "season" is essentially "on time."
They don't get much better than this! Perfect agreement w/ mid-transit time, depth and length.
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.
