During my holiday the weather was fine for sat observing in the first week.
Later more clouds and some rain.
With my boat (that also is my house) we sailed up the river Maas all the way
till Anseremme, a little town just south of Dinant, Belgium.
On August 11th I went by bus and train to Charleville in France, inside the
totality zone of the solar eclips. I was fortunataly at the right spot.
As I arrived in Charleville there was some rain, but at 10 o'clock the
clouds
got thinner. From 11:07 (local time) the moon moved in front of the sun. Now
and then the clouds got thicker, but around totality they were thin, with
some
occasional cloudless spots. I used my videocamera with a solar screen in
front
to tape the event. The corona was good visible, with some orange glow due to
thin clouds. Also the diamondring was spectacular as the sun re-appeared.
It was my first solar eclips, an event not to forget.
As we sailed the rivers I made obs from different places.
