Title: Status of the BRAMS activities


1
Status of the BRAMS activities Hervé Lamy
2
BRAMS team
  • Hervé Lamy
  • Johan De Keyser
  • Sylvain Ranvier
  • Emmanuel Gamby
  • Stijn Calders
  • Michel Anciaux

3
BEACON
4
Network of radio receiving stations
Jean-Louis
  • Future stations
  • Genk
  • Leuze
  • Seneffe
  • Lille?

5
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

8
Access to the BRAMS data Hervé Lamy Emmanuel
Gamby
9
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
    Ranvier
