An interesting news was published on MeteorNews about a fireball over Benelux on 10 October 2018. ( https://www.emeteornews.net/2018/10/13/fireball-over-benelux-10-october-2018-211411-ut/).
This fireball was also seen by 17 FRIPON cameras ! From the Netherlands, Belgium, France, Germany and Switzerland. Table 1 lists the orbital parameters close to these of CAMS but with an eccentricity lower than 1. This was a very low inclination object that remained high in the atmosphere, even the speed was rather fast and constant until the catastrophic end.
