Our group consists of five astronomy enthusiasts who study physics at Tartu University. Twice a month we attend
astronomy lectures at the Astronomy Club of Tartu Old Observatory. These
lectures are public to all people who are interested in the subject.

Tartu Old Observatory
- Latitude: 58° 22' 47''.2
- Longitude: 26° 43' 17''.7
- Time Zone: Eastern European Time (EET) i.e. GMT+2
- Height from sea-level: 67 metres
- Equipment: 8-inch Zeiss refractor (since 1911, recently
repaired)
Observation of the Solar Eclipse (12th October)
We used the 2D
method as described on the Astronomy On-Line website. We created the
Sun's image with a spyglass.
The eclipse began at 13:15 UT (16:15 local time) and lasted beyond the
sunset (15:16 UT). Unfortunately we were able to observe the eclipse only
for half an hour -- since 13:45 UT we were clouded out. The maximum should
have appeared approximately at 14:25 UT.
Measurements were performed on the projected image. We made the last
measurement at 13:43 UT with
H = 116 mm
W = 174 mm
Thus the estimated distance to the Moon (using 2D method): 470000 km.
