Main scientific goals

• Trajectories ? 1 student from ULB Allick Nelo
  from EPHEC
• Meteoroid fluxes
• automatic detection (PE 2 students from EPHEC)
• Observability function (SC, CV)
• Properties of meteoroid ? analysis of meteor
  profiles (speed, deceleration, ionisation, mass,
  etc)

6
Additional scientific goals

• VLF emissions ? search for VLF / VHF conjugated
  events in Humain (with F. Darrouzet)
• Detection and small-scale structures of solar
  flares (with ROB)
• Properties of the upper thermosphere (wind
  velocities, temperature, etc with RMI)

7
Meteor radar in Dourbes

• BISA
• Goal study of meteors, comparison of fluxes
  with forward back scatter systems
• Status preliminary design done, material is
  being procured, work should start in summer 2012

Creation of the spectrograms

• Software developed by EG to automatically create
  spectrograms from WAV files (replace Spectrum
  Lab)
• Still a few problems with data from several
  stations

10
Whistler observations

• BISA project
• Goal detect Whistler waves with a VLF antenna in
  Humain
• Part of an international project AWDANet
  (Automatic Whistler Detector and Analyzer
  systems network)
• Status system operational, 3 months of data
  during last year. Less whistlers than at other
  AWDANet stations.
• Contact persons Fabien Darrouzet, Sylvain
