On February 27 and 28, two major fireballs have been widely observed, reported and filmed over France and Great Britain. Both of them are potential meteorite droppers: trajectory calculations now gives the opportunity to look for interplanetary rocks!
French fireball on February 27, 21h 43min UT
The first fireball lasted slightly more than 5 seconds on February 27, 21h 43min 27sec and was reported by more than 80 witnesses from all regions of France South of Paris. According to Fripon (Fireball Recovery and InterPlanetary Observation Network), which video network captured the event on 9 cameras, the fireball magnitude reached -12 to -13, and it was associated to the atmospheric entry of a 500 g meteoroid coming from the external parts of the asteroid belt at a 21 km/s speed and a 50° inclination.
According to Fripon calculation, around 150 g of meteorites could have survived the atmosphere crossing and could have landed slightly East of the Aiguillon village, in Lot-et-Garonne (South-Western France).
British fireball on February 28, 21h 54min UT
Nearly 24h after this first event, a very slow fireball was very widely reported by British citizens, with more than 1100 reports!!! This event occured on February 28, 2021, at 21h 54min UT and was observed and heard, as many persons “reported hearing either a sonic boom or a rumbling noise” according to UKMON (United Kingdom Meteor Observing Network). It was also captured by the UKMon camera located in Wilcot (Wiltshire).
According to UK Fireball Alliance calculations, the meteorite strewn field would be located East of Gloucester (Glioucestershire).
