• Shouldn’t we do something like the ‘radio meteor school’? Bring together all the teams working on multi-station setups and orbit determination software? MOD WS #03 - MET-RSSD-HO-056/1 -, 17 Apr 2010 2

The ISSI team in Bern, 2008 • • • ISSI workshop took place 24 -28 Nov 2008, Bern, Switzerland http: //www. issibern. ch/teams/observemeteo/ Results were published in WGN: Ø Koschny, Arlt, Barentsen, Atreya, Flohrer, Jopek, Knofel, Koten, Luthen, Mc Auliffe, Oberst, Toth, Vaubaillon, Weryk, Wisniewski; WGN 37: 1 (2009), 21 -27, Report from the ISSI team meeting “A Virtual Observatory for meteoroids”. • Main points: Ø Ø Ø Ø Ø Concept of ‘sessions’ and ‘periods’ was confirmed VMO shall be a central repository – it is an offer, not a requirement The interface format shall be specified (see next ISSI workshop) Dedicated section on fireballs – topic of a workshop coupled to the next IMC, called Fire. Works, organised by Maria Gritsevich with Tolis Christou Use heliocentric coordinates, not barycentric Give reference for which orbit code was used to produce any given orbit It is recommended to store ‘distortion maps’ to allow assessing the quality of an astrometric fit Still open: Is the accuracy of automated orbit computations from cheap video cameras sufficient for scientific analysis? Still needs more work. Involve a broader audience in the process of defining the VMO (that’s why we’re here!) MOD WS #03 - MET-RSSD-HO-056/1 -, 17 Apr 2010 10
The ISSI team meeting 2009 • Barentsen, Arlt, Koschny, Artreya, Flohrer, Jopek, Knofel, Koten, Mc Auliffe, Oberst, Toth, Vaubaillon, Weryk, Wisnieweski, Zoladek, WGN XX: X (2009), The VMO file format, I. Reduced camera meteor and orbit data • Defines a data model and a detailed XML file format for storing meteor camera and meteor orbit data • Gives detailed description of file formats • Still open: fireball requirements (see Fire. Works workshop); requirements from network coordinators not involved so far; nothing about radar or radio forward scatter data (see IMC 2010) Mariusz Geert MOD WS #03 - MET-RSSD-HO-056/1 -, 17 Apr 2010 11
Goals of this meeting • Detailed discussion of UFOcapture and related software • Discussion on different points related to meteor detection and archiving • What is still missing in the VMO to properly archive all existing data (get ready for IDIS review in Sep 2010) • Introduction into the SPICE toolkit • Work on a common dream!
