Mit CoRoT auf Planetenjagd
Seid Jahrhunderten war es ein Traum Planeten ausserhalb unseres Sonnensystems zu entdecken. Mit der
ersten indirekten Entdeckung eines extrsolaren Planeten im Jahre 1995 wurde dieser Traum Wirklichkeit.
Inzwischen sind bereits 300 Planeten ausserhalb unseres Sonnensytems indirekt entdeckt worden. Neuste
Forschungen ermoeglichen aber nicht nur die Masse und die Bahnen von massereichen Planeten aufzuspueren,
sondern es ist jetzt auch moeglich, sehr viel mehr ueber die Planeten zu erfahren. Von herausragender
Bedeutung ist dabei die Satellithenmission CoRoT, da es mit diesem Instrument moeglich ist, Planeten
zu erkunden, wie es mit bodengebundenen Teleskopen nicht moeglich ist.

Automatic Universal CCD-Astrometry of Minor Planets
Concepts for a completely automatic scheme to determine the positions of minor planets on ccd
frames will be discussed. There, special attention is given to the universal aspect, i.e.
that the results should be of high accuracy independent of the hardware equipment used for
observations and astrometrical reduction. Finally, the new software package "MpCCD", which
has been developed to meet these requirements, will be outlined.

Observation of a mutual occultation of Uranian satellites
At the moment the plane of the tracks of satellites from Uranus
is at its side view. This means that mutual occulations occur.
The lecture show an observation of an event.

The construction and use of the ELMAHARU Obsrvatory
In this presentations Harrie Rutten shows his Observatory.
It contains two observatories.
One is a run-off roof observatory, the other is a lift-off roof observatory.
The first is housing a 250 mm F/20 Schmidt Cassegrain for visual observations,
the second a 10" F/6.3-> F/4 for video observations.
Recent observations of occultations in Finland
The Lunar occultations that were observed in Finland during 2007 and 2008
included the daytime occultation of Regulus in May 2007, the daytime
occultation of Venus in June 2007, and several occultations of the Pleiades
in 2007 and 2008.
"Occult Watcher" - an Interactive Tool for Planning Asteroid Occultation Observations
Presentation of the latest version of "Occult Watcher", a software written by
Hristo Pavlov. How to use it, what is new, things to come. Finally a short
brainstorming with the participants about features to add in future versions
of "Occult Watcher".
Practical experience with camera WAT 120N
Contribution deals about using of this camera for observing asteroidal occultations.
It describes what is possible to see under what conditions at time under very bad conditions.

Some experiences of an asteroidal occultation observer
At first I will explain how I do my observations and why. Then the occultation of Geranium
and Winchester in spring 2008 will be discussed. For the predictions of asteroidal
occultations I also use Occult V. I want to share some experiences with this programm too.
As the presentation is still under construction, the definitive description will follow.
Editing of occultation video as a good way for accure timing and some more...

Total solar eclipse on 1st August 2008 near Nowosibirsk - a successful expedition
30 - 45 min
We report shortly about local circumstances in the Novosibirsk region, about the
cooperation with Russian people, show some pictures and - as the most important
result - some Bailey Bead videos recorded by the observers of the Spanish-German expedition.
An early asteroid occultations ?
Some notes in published 19th century observations indicate there might be observed
asteroid occultations in those times. However the texts in old German are not written
clearly and interpretation is not easy. A discussion about these text is supposed.
Wieck - an occultation in slow motion
30 - 60 min
While usually a set of several light curves is required to determine an asteroid's size
and shape, a single recording of Wieck's occultation of HIP 22157 on 2008 Feb 08 was
sufficent to retrieve a number of interesting data. A remodulation of the light curve
rendered it possible to deduct various diffraction effects.

Appeal: Pictures of former ESOPs
Since a few years web sites are beautiful tools to present ESOPs. Another nice thing is
the memories of ESOPs. Some sites are still in the air, but some are closed. What a pity.
DOA likes to make a historical overview of ESOPs. Therefore we like to have pictures and story,
but mainly pictures.
Do you have pictures, please send them of take them to this ESOP, digital or on
paper (good quality needed).
Next ESOP in Cracow we present our new "Memories on ESOPs".
