Bart De Pontieu
EUROSOM 2 is the second edition of the EUROpean Satellite Observers Meeting. It is organized by the Belgian Working Group Satellites (BWGS). The first edition was held in October 1994, in Hasselt, Belgium.
This is the first progress report. Indicated are a few changes/additions to the program. Please refer to the First Announcement in the previous issue of Flash for more details. A registration form is added to this issue of Flash. Don't hesitate to contact us for more details. Eurosom 2 now also has a Home Page on WWW at http://www.rzg.mpg.de/ bdp/eurosom.html
We convene during the weekend of October 19 and 20, 1996. On Saturday we convene from 9h30 in the morning until 18h in the evening, with a lunch break and various coffee breaks. On Sunday morning we reconvene at 9h30. Eurosom 2 ends at 17h on Sunday afternoon.
Eurosom 2 will be held in Belgium, in the city of Ghent. We found a nice hotel situated in the historical center of Ghent. The medieval city of Ghent offers great sight-seeing spots as the Castle of the Counts and the gothic St. Baafs Cathedral.
Several speakers have already agreed to try to attend Eurosom 2 and give invited talks. If all circumstances are favourable, the following people will be present to give an invited talk:
Björn Gimle, Junibacken, Sweden.
Bjorn has been very active on SeeSat-L where he provides regular predictions of decay times of satellites. He will probably talk about the orbits of decaying satellites and the mathematical methods and software tools for decay predictions. He will also talk about software to prepare, analyze and report observations.
Paul D. Maley, NASA Johnson Space Center Astronomical Society, Houston, Texas, United States.
Paul supervises the work of 13 engineers in the Payload Operations Unit of Rockwell Space Operations Company at the NASA Johnson Space Center. Aside from being very active in solar eclipse observing and the International Occultation Timing Association (IOTA) of which he is vice president, Paul is also a very experienced satellite observer. His talk will probably center on low light level video applied to satellite tracking. More specifically he will talk about the observation of Shuttle reentries, reentry of the Shuttle external tank, the SEDS tether, the IAE antenna released from the Shuttle in May 1996, an earth satellite as seen from the Space Shuttle, Barium cloud experiments, etc. He will probably also show video of some BWGS targets and discuss the pro's and con's of using this type of application for flash period data collection.
Mike McCants, Austin, Texas, United States.
An active observer for more than 30 years, Mike is also renowned for his orbital calculations (decays, flash periods, synodic effects, orbital debris...). Mike will probably talk about advanced measuring techniques for flashing satellites, using a multiple memory stop watch, and the effects on e.g. the flash period accuracy. He will probably also discuss measurements of the synodic effect of flashing rockets. Possible other subjects include observations and calculations of exploded rockets and resulting debris, decaying satellites, etc... Mike will bring slides with 'special' observations through the years.
Jay Respler, New Jersey, United States.
Jay is an experienced observer, who is specialized in observations of space debris, which nowadays also gets a lot of attention from professional scientists because of the danger it poses to active and manned payloads. Jay is currently working on a database of observations and magnitude estimates of all satellites brighter than magnitude 13. He will discuss his experiences and measuring techniques.
Kurt Jonckheere, Oostende, Belgium.
Kurt has been an active observer for 8 years, and is currently coordinating the purely Belgian activities of the BWGS. He will talk about his recent (succesful) efforts to predict accelerations of flashing rockets using changes in the orbital elements.
Bart De Pontieu, Munich, Germany.
Bart is a Belgian expatriate who has been observing satellites for 12 years. He has been coordinating the activities of the BWGS since its creation in 1987. He has been editor of the monthly BWGS newsletter Flash for most of the first 100 issues. He is also maintaining SeeSat-L and will talk about his method to determine the rotation axis of flashing rockets, and will present recent results and their application to accelerating rockets.
It now also looks like Alain Grycan and Eric Laffont will attend and present an update on their efforts in high-resolution imaging of MIR and Shuttle. We also hope to get Ron Dantowitz to present the high-resolution observations he and his group have obtained of the Space Shuttle-MIR dockings.
Finally, video material of the Canadian Space Agency will be presented. It was taken during on board of a sounding rocket flight. During this experiment a spinning sub-satellite was deployed while it remained connected to the main payload with a tether. Also, footage of the TSS-1R taken by Dr. Kym Thalassoudis from Australia will be presented.
There is still room for a few contributed talks of 20 to 30 minutes. Please contact Bart De Pontieu for details.
How do I register ?
Fill in the registration form for you and all accompanying persons and pay 400 BEF before September 15, 1996.
How do I pay ?
All participants should pay the registration fee of 400 BEF (Belgian Francs) before before September 15, 1996. It includes general organizational costs and the proceedings (which you will receive a few months after the meeting). Accompanying people do not need to pay the registration fee. The registration fee can not be paid back to you in case you eventually can't attend Eurosom 2. The costs for food and lodging (see registration form) can be paid at the meeting itself, but only in BEF.
Method of payment depends on where you live:
Belgians pay to our postal account 000-1600453-50, WG Kunstmanen, Stuiverstraat 558, B-8400 Oostende.
Germans pay to Bart De Pontieu's German Konto (in DEM): Konto 30732 01620, BLZ 250 206 00, DSK Bank.
Americans pay by sending a check (in US dollars) to Mike McCants, 5105 Crestway Drive, Austin, TX 78731, USA.
All others pay by International Postal Money Order or Eurocheque to Jean De Weerdt, Dr. Van Oyelaan 5, B-8470 Gistel, Belgium.
Please use the following exchange rates if you're paying in DEM or USD: 1 DEM = 20 BEF, 1 USD = 29 BEF.
