Tohban Report 12/12/21 - 12/18/21 Tohban Name: (updated by Muhammad Fraz Bashir [12-20-2021]) Special Notes ------------- Both ELFIN-A and ELFIN-B observed few interesting (mentioned by "*" ) precipitation events ( in range of 300 keV to ~ 1 MeV) during the time of enhanced AE index on dates: Especially on Dec, 14 & 15 by ELFIN A and on Dec 16 by both ELFIN A and B. There is no data available for Feb. 12 from ELFIN-A and Feb. 13 and 15 from ELFIN B. There are few events mentioned by "T" where the parallel and anti-parallel fluxes are suddenly vanished ELFIN A inner belt collections are fine but No Inner Belt Collection by ELFIN B. There are several entries in automatic report which has merged two intervals to one longer interval.
