Lectures

up-to-date: September 3, 2008

Dr. Eike Günther of the Thüringer Landessternwarte
Hunting planets with CoRoT
60 minutes
For centuries it was a dream to detected planets orbiting stars other than the sun. With the first indirect discovery of such an object this dream became reality in 1995. Now more than 300 planets have been discovered outside our solar-system. New methods not only allow to find out much more than just the mass and orbits of such objects. Particularly important is the satellite mission CoRoT which allows to detect planets that can not be detected with earth-based telescopes.

Dr. Ralf Langhans of the Lohrmann-Observatorium from TU Dresden
Automatic Universal CCD-Astrometry of Minor Planets
60 minutes
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.

Harrie G.J. Rutten
Observation of a mutual occultation of Uranian satellites
20 minutes
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.

Harrie G.J. Rutten
The construction and use of the ELMAHARU Obsrvatory
20 minutes
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.

Matti Suhonen
Recent observations of occultations in Finland
15 minutes
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.

Oliver Klös
"Occult Watcher" - an Interactive Tool for Planning Asteroid Occultation Observations
45 minutes
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".

Vaclav Priban
Practical experience with camera WAT 120N
10 minutes
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.

Henk de Groot
Some experiences of an asteroidal occultation observer
30 minutes
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.

Pawel Maksym
Editing of occultation video as a good way for accure timing and some more...
25 minutes

Pawel Maksym
ESOP 2009 - Niepolomice - Poland
25 minutes
Lecture together with Youth Astronomical Observatory of Niepolomice.

Wolfgang Rothe, Martina Haupt, Sven Andersson, Konrad Guhl
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.

Jan Manek
An early asteroid occultations ?
15 minutes
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.

Andreas Eberle
Wieck - an occultation in slow motion
30 - 60 minutes
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.

Harrie G.J. Rutten
Appeal: Pictures of former ESOPs
10 minutes
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".

Konrad Guhl, Sven Andersson, Martina Haupt
Baily beads "observation for measurement the solar diameter - first results from the eclipse 1. August 2008"

20 minutes
