The weather was very cloudy in our area.
At 01 am , I rode my car for 40 km westward, from Brive,
in order to find a little less clouds than it was expected in Uzerche.
Then I could see the eclipse rather well.
But without our telescope, I did not make good pictures of the Moon during the complete eclipse.
The reason is that a long exposure was required (several seconds) :
then, without the motor of the telescope I was not able to follow the moving Moon.

1 h 43 UT : the Moon entered the Earth shadow.
3 h 00 UT : beginning of the complete eclipse.
3 h 51 UT : end of the complete eclipse.
5 h 09 UT : the Moon got out of the Earth shadow.
On the 21st of february :
* in France and United Kingdom, the legal time is UT + 1 h;
* in Sweden, the legal time is UT + 2 h.




Beginning of the eclipse (01 h 58 UT , ie 02 h 58 in France).
Canon EOS300D + zoom lens (up to 3 x 300 mm) ; exposure 0.005 second.
The Earth shadow is on the top left part of the Moon.



Complete eclipse (03 h 18 UT , ie 04 h 18 in France).
Canon EOS300D ; exposure 2.5 seconds.
On the right, we can see alpha Leonis (Regulus) , a bright blue star.
The Moon is red because the red rays of the Sun light are deflected by
the earth atmosphere, while the shorter wave rays are absorbed by it.



Complete eclipse (03 h 31 UT , ie 04 h 31 in France).
Canon EOS300D ; exposure 1.3 second.
On the right, we can see Regulus.
On the top left, we can see Saturn.



End of the eclipse (04 h 38 UT , ie 05 h 38 in France).
Canon EOS300D + zoom lens (300 mm) ; exposure 0.2 second.
The Earth shadow is on the right part of the Moon.

On 8th of February, we organized 2 observations.
During the first one, from 12.00 to 2.00 pm, we've pointed at the Sun, the Moon, Venus.
We also tried to point at Jupiter but we did not succeed.




The 2nd observation was organized during the night, from 9.30 pm to midnight.
We were 13 persons : 3 teachers, 4 pupils, 6 other persons.
We've seen different constellations :
- Ursa major with the double star Mizar, 2 galaxies near Ursa major (M81 & M82) ;
- Ursa Minor, Cassiopeia, Auriga (Capella) , Canis major (Sirius) , ...
- Perseus with the double open cluster (NGC 869 & NGC 884) ;
- Andromeda with the Great galaxy (M32 + M31 + M110
- Taurus : Aldebaran, the Pleiads, and Mars,
- Orion : Betelgeuse, Rigel, Great Nebula (M42)...
- Gemini (Castor & Pollux and the planetary nebula NGC 2392) ;
- Leo with Saturn ;
- Coma Berenices with the open cluster Melotte 111 and the globular cluster M53.
