What does BRAMS provide to amateurs?

• Provide all material for free (identical in all stations)

• Access to data from all stations & archive of the data

• Real-time observations to show to the public

• A possibility to educate the public to meteors & radio science (BISA provides posters and articles)

What do amateurs provide to BRAMS ?

• Host of most of BRAMS stations

• Save data locally on hard disks & make a copy on USB sticks (64 GB) sent every month to BISA for archiving

• Electricity bill supported by BRAMS participants

• Multi-stations observations allowing to retrieve meteor trajectories

• Participation to some projects (e.g. automatic detection of meteors in spectrograms)

Summary

o BRAMS is a new tool to observe & characterize meteorso It is the result of an active Pro-Am collaboration with

mutual benefito In the future BRAMS should be extended outside of

Belgium as meteors do know anything about frontiers …
