  Lunar Occultations, OccultWatcher and WINOCCULT any news ?

What is the future of WINOCCULT ? Program language, .NET, etc.
Implementation of GAIA data in WINOCCULT and OW
OccultWatcher ... What stars and events will OW handle ?

• Monday, 18th 14h00 - 17h30 :
  Distributions of predictions, better alerting observers

Photometry in image sequences, linearity of detectors, spectral response, noise
Improving historic observations

  Observation of occultation events :

Effect of GAIA catalogue on the community
How many occultations per night with a certain telescope diameter ?
Is it still usefull to travel ?
Mass analyzing and archiving of data.
A database of results... Will Euraster do this ?
Should we run a testsite ?
Two telescopes in N/S direction for better spatial resolution.
IOTA-ES 0.5m mobile instrument in combinatiion with a fixed site ?
