Observing meteors using radio techniques “who knows the principle of radio meteor observation?” advantages of radio detection: Day and night (daylight showers) Independent of the weather Observing a lower mass range than visually

BRAMS network ~30 stations all over Belgium ~8000 spectrograms per day

Automatic detection algorithms underdense meteors: we have two reliable automatic detection methods difficult to classify more complex meteor shapes automatically

Automatic detection algorithms underdense meteors: we have two reliable automatic detection methods difficult to classify more complex meteor shapes automatically

https://www.radiometeorzoo.org - live classification of one spectrogram - each spectrogram is sent to 10 different volunteers

Results More than 5000 registered volunteers classified meteors in almost 30.000 spectrograms 5000 4000 3000 2000 1000 More than 10.000 volunteers in total Half of them at the launch, afterwards a linear growth Aug. 2016 Jan. 2017 April August

Results At the day of the launch on 12 August 2016, more than 12.500 spectrograms were processed 12500 5000 Perseids 2016 action At the first day after official launch, almost 12500 spectrograms were processed.

Results Volunteers classified spectrograms coming from 5 receiving stations for the Geminids 2017 action 12500 5000 Geminids 2017 action

Results For the Lyrids 2017 action, only one station has been processed 12500 5000 Lyrids 2017 action

Results For the Perseids 2017, more than 10.000 spectrograms were processed in two days 12500 5000 Perseids 2017 action

Results sporadic background subtraction

Future plans Data quality: automatic removal of mistakes/errors/...

Future plans Data quality: automatic removal of mistakes/errors/... Observability function Use RMZ as the ground truth for the automatic detection algorithms Observability function (to take into account the factors (geometry, gains, ...) that influence the sensitivity of the setup)

Call for action Thanks to the Radio Meteor Zoo, BRAMS can for the first time analyze several showers per year There are two laptops in the poster room where you can try the Radio Meteor Zoo yourself
