Tohban Report 12/13/20 - 12/19/20 Tohban Name: Jiang Liu (updated [12/22/20]) Operator Notes -------------- Downlink capability is less than half due to overlapping passes and Wallops still being down. Special Notes ------------- -The missing days' data may come back later, so this file is subject to change. -The last two passes of ELFIN-A show very similar precipitation spectra, but their L values are completely different. This is shows propagation of high-energy plasma in 3-hour scale.
