Timing of transits are well-behaved, so far.
OOT LCs show nothing statistically significant, so far.
Table of observations
This is a combination of the previous two transit datta sets.
8c29SBL1 Bart's clock must have been set off by one hour (we all do this occasionally).
Excellent! This is the best amateur LC that I've ever seen! Notice the abrupt ingress and egress changes and the strong limb darkening shape.
First submission by this group (Barbieri, Borsi, Conti, Marchini & Marchini). Good job considering full moon and V-band.
First submission by Staels; great quality LC!
Perfect agreement with consensus!
High air mass at beginning, poor seeing & wind at end that terminated obsns.
Unusually flat OOT for BB-filter.
FOV = 25.5 x 18.7 'arc. XO-2 is indicated. It's same color
binary companion is 31 "arc to the south and is 0.08 mag brighter.
The companion is an ideal reference star since it's close-by, same
brightness and same color.
Beware of Star #10 which is a small-amplitude, short-period
variable (30 mmag amplitude, 1 hour period). Don't use it as a reference
"Comp" is the star 31"arc to the south.
