Parallel Strands • Two parallel strands • VOEvent standard • HTN and eSTAR standards • VOEvent standard has been designed to • transport timely information concerning transient events • HTN standards has been designed to • allow the recipient of an event message to negotiate for, and obtain, follow-up observations to these reported events from a heterogeneous collection of networked telescopes ADASS XVII, Sept. 2007

Smarter than average? • How well should one bit of software believe other bits of software when they tell it somewhere? • Currently running simulations in Exeter • keeping track of scores from telescopes and whether they actually returned data, i.e. are they “lying” to us? • using this to modify our decision making process in the future, hopefully weighting things towards the telescopes that don’t “lie” about how well they can perform observations • Emerging social conventions?

Event Network Closing the loop DB Robonet-1.0 User Agent Embedded Agents • Allows real-time analysis of incoming micro-lensing data from PLANET, OGLE, MOA, MicroFUN and Robonet-1.0 • looks for deviations that might be plantetary anomalies • asks for more data if it’s not sure • triggers target of opportunity if it is sure ADASS XVII, Sept. 2007

Conclusions • Autonomous observing • IVOA standard VOEvent messaging • HTN standard RTML messaging • eSTAR represents a “turn-key” system • Operating in three modes • event driven • long term monitoring • reactive follow-up • See http://www.estar.org.uk/ for more information ADASS XVII, Sept. 2007
