The eclipse could be observed was successful!
While there were some thin clouds above
the eastern horizon upon our arrival, but they vanished after
the first contact completely so that we could observe the
interesting phases of darkness under a perfect cloudless sky.
At our observation place we made several
videos and photos with different focal lengths from 8mm fisheye
to 500mm telephoto lens, weather recordings and measurements of
the ambient brightness.
Unfortunately, no large sunspot groups were decorating the
solar disk in the partial phases.

seen in the appearance of the corona. The southern hemisphere is
already appearing as a minimum corona, while the northern
hemisphere is showing more helmet streamers, indicating the higher

At the first contact there were thin clouds in
front of the Sun. Detail of a fish eye image.
Because the observation
place was not exactly on
the centreline, the
position of the third contact was not
exactly opposite of the second
contact on the solar disk.
Therefore, the orientation of the shadow
bands after the third contact
was a little different. They
extend almost horizontally,
according to the position angle of the solar crescent in
the sky. After the third contact,
the shadow bands were even
fainter than before the second
contact. The reason
is probably the decreasing of turbulence and convection
in the atmosphere.

observation place I recorded the weather development with my
mobile weather station, based on a C-Control
. The Unit was placed 1 m above the ground, a concrete
surface near the beach of Pedanda. The temperature in 1 m height decreased
from a maximum of 32° C at 07:41 local time (UTC +8h), shortly
after the first contact down to 27.3° C at 08:43 local time. This minimum was achieved 4
minutes and 30 seconds after the third contact. Afterwards the
normal daily temperatures were quickly achieved again. I also made
measurements near the ground (10 cm above the floor) and
directly on the floor, but the
latter were partially disturbed by direct sunlight.
Brightness sunk downto 5 Lux during totality.
The total eclipse of 2016 is part of the Saros-Period
130, which lasts from the year 1096 and will end with its eclipse
number 73 in 2394. In this period there will occur every 18 years
and 18 days an eclipse. It is containing 30 partial eclipses. The
other 43 ones are total, with durations between 01:14 minutes up
to 6:57 in the year 1565. As usually some annular or hybrid
eclipses occur in a Saros period, number 130 with exclusively
total or partial ones is quite remarkable. The image left is
showing a Saros-snail, indicating how the lunar shadow hits the
earth at the maximum of each eclipse. Click into the image to
