Conjunctions: BBF-radar and Swarm-radar

Database of conjunctions to support 'Bursty bulk flow ionospheric impacts from triple-conjunctive observations', H. George, submitted to Annales Geophysicae in May 2026. 

Two sets of conjunctions are provided: conjunctions between the magnetic footpoints of BBFs detected by THEMIS and selected radar stations, and conjunctions between the Swarm satellites and selected radar stations. Conjunctions are defined as the centroid magnetic footpoint or Swarm satellite being within 400 km of a radar station.  Conjunctions are provided between Swarm and radar stations for the Swarm-A and -B satellites, as Swarm-C is very near to Swarm-A and is not expected to provide any new conjunctions.
