It all started at the IMC 2005 (15-18 Sep 2005, Oostmalle) when Koschny
& Kac had a discussion at the bar on coordinating meteor orbit
computations…

• Shouldn’t we do something like the ‘radio meteor
school’? Bring together all the teams working on
multi-station setups and orbit determination
software?

ISSI workshop took place 24-28 Nov 2008, Bern, Switzerland

Results were published in WGN:


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 FireWorks, 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!)

The ISSI team meeting 2009

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 FireWorks workshop);
requirements from network coordinators not involved so far; nothing
about radar or radio forward scatter data (see IMC 2010)

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!
