Summary:

Yesterday I did 2 observation sessions, from 20:00-20:45 and from

22:30-23:45. The objective was to observe the transits and

occultations of the moons of Jupiter. Two events were observed and

timed:

- Transit egress of Io at 20:20:35.

- Occultation reapperance of Europa at 23:36:04.

The shadow egress of Io was a planned observation, but the shadow

could not be seen because of clouds passing in front of Jupiter.

Furthermore, the Moon (almost full) was observed and photographed and

the Pleiades could be seen from the telescope.

The plan for tonight (in case of clear skies) is to realign the

telescope since it is currently not well aligned and make some

observations of Jupiter and the Moon. No specific events of Jupiters

moons can be observed tonight.

Objects Viewed:

- Jupiter, Io, Europa, Ganymede, Callisto.

- The Moon.

- The Pleiades.

Problems Encountered:

None.
