Main scientific goalsMain 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…)
Annual BRAMS meeting – Grimbergen – 09/06/2012
Additional scientific goalsAdditional 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)

Meteor radar in DourbesMeteor 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 spectrogramsCreation 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

Whistler observationsWhistler observations
• BISA project• Goal: detect Whistler waves
with a VLF antenna in Humain• Part of an international
project AWDANet (Automatic Whistler Detector and Analyzer system’s network)
• Status : system operational, 3 months of data during last year. Less whistlers than at other AWDANet stations.
