Conferences about BRAMS at OCA in Neufchateau during RACA and at Dourbes during a visit of the CAM members
On May 30, Hervé Lamy gave a conference about "Radio detections of meteors with the BRAMS network" at the Observatoire Centre Ardennes (OCA) in Grapfontaine during the RACA 2019. The presentation can be found here. The same presentation was given in Dourbes on 22 June during a visit of the site by members of the Cercle Astronomique Mosan (CAM).
Conference about BRAMS in Woluwé St-Lambert
On April 4, Hervé Lamy gave a conference about "Radio detections of meteors with the BRAMS network" at the radioamateur club ON5UB in Woluwé St-Lambert. The presentation can be found here here.
Presentation of CAMS / BRAMS comparisons at the CAMS annual meeting
H. Lamy gave a talk about comparisons of data obtained between the CAMS-Benelux optical network and the BRAMS radio network during the annual CAMS meeting organized at the MIRA Observatory in Grimbergen on 10 March 2019. The presentation can be found here.
BRAMS annual meeting 2018

Third bright fireball observed in June on 29 June 2018
Another bright fireball was captured by the FRIPON camera in Brussels and the newly installed one in Liège on 29 June around 21H30 UT (23H30 local time). You can find additional information on the IMO website. This time, most BRAMS stations were detecting a very nice overdense epsilon-like meteor echo. Only the stations located to the south-east of Belgium (Humain, Tintigny) did not detect it. Below you can see the FRIPON detections with the cameras in Uccle and Liège as well as BRAMS spectrograms from Kampenhout and Overpelt (note that the meteor echo occurs to the left of the spectrograms after approximately 30 seconds).
Tests with the BRAMS transmitter in Dourbes
On 25 June 2018, we made some tests resulting in the transmitter being switched on and off several times during the day. First, we made some tests with the power amplifiers that are going to be used for the future BRAMS radar. Second, we also measured how well adapted our crossed dipole is, i.e. we measure the amount of transmitted power reflected at the antenna due to the non-perfect adaptation of each dipole. The measurements are currently analyzed. Very soon we will probably replace the dipoles and small cables. At the same time, our colleagues from the workshop were installing the 8m x 8m metallic grid that will act as the reflector for the future BRAMS radar transmitter. The five antennas for the future interferometric receiving system have also been installed. Below you can see the reflector and two of the antennas (including the central one which is a crossed 3-elements Yagi) of the future interferometer.
