ok, then it makes no sense to calculate the distance to Sun. We need the
Times of all 4 Contacts for that. But we can calculate Earth Diameter with the
times of fist and second Contact + Coordinates of the Telescope. That can be
done by the younger one kids...

we have free horizon to eastern, so it will be no Problem, the sun is about
2 hours over the horizon here at first contact...

that would be great! Yes, we will also look for the
"Drop-Phenomena"...

We
are looking for partners all over the world, so I will translate our Paper into

You
will get the paper early enough. Last week I showed a Film about the different
expeditions and how the Astronomers calculated the distance. The kids are very
excited about the chance, to see the Transit and do that historic
calculation...

We
have no “rainy season”, but weather is also a problem to us! Last year at
Mercury Transit we had thick fog in the morning, and at the particular eclipse
we had clouds the first 10 minutes...

In
This
is the reason, why we are looking for some single Persons observing the Sun,
private Observers maybe can record with a Voice recorder or by a Camcorder with
tone for time signal...
I
will observe the Transit with my youth group 120 km away from Stuttgart on a
region called "Schwäische Alb", that’s an limestone highland with
better seeing conditions and good view to all directions. We also will record
the time signal with a camcorder...

I also try to take pictures with low
Equipment.

I know, it
will be not easy, thanks for your offer to help.
