Status of the BRAMS activities Hervé Lamy Annual BRAMS meeting – Grimbergen – 09/06/2012
BRAMS team • • • Hervé Lamy Johan De Keyser Sylvain Ranvier Emmanuel Gamby Stijn Calders Michel Anciaux Annual BRAMS meeting – Grimbergen – 09/06/2012
BEACON Annual BRAMS meeting – Grimbergen – 09/06/2012
Network of radio receiving stations + Jean-Louis Future stations : • Genk • Leuze • Seneffe • Lille? Annual BRAMS meeting – Grimbergen – 09/06/2012
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…) Annual BRAMS meeting – Grimbergen – 09/06/2012
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) Annual BRAMS meeting – Grimbergen – 09/06/2012
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 Annual BRAMS meeting – Grimbergen – 09/06/2012
Access to the BRAMS data Hervé Lamy Emmanuel Gamby Annual BRAMS meeting – Grimbergen – 09/06/2012
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 Annual BRAMS meeting – Grimbergen – 09/06/2012
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 system’s network) • Status : system operational, 3 months of data during last year. Less whistlers than at other AWDANet stations. • Contact persons : Fabien Darrouzet, Sylvain Ranvier Annual BRAMS meeting – Grimbergen – 09/06/2012
