Observations of Short-period Current Sheet Flapping Events in the Earth's Magnetotail
Deng, X. H.; Huang, S. Y.; Xu, S. B. +9 more
The flapping motion of the current sheet, with the period from several minutes to tens of minutes, is one common dynamic phenomenon in the planetary magnetotail. This Letter reports on one current sheet flapping event with the short semi-period of ∼6 s on 2017 July 17 in the Earth’s magnetotail for the first time using the Magnetospheric Multiscal…
Close up observation and inversion of low-altitude ENA emissions during a substorm event
McKenna-Lawlor, Susan; Lu, Li; Balaz, Jan
During a series of substorm events on November 12 2004, the Neutral Atom Detector Unit (NUADU) flying onboard the TC-2 spacecraft observed, close to perigee, bright low-altitude Energetic Neutral Atom (ENA) emissions from both north and south poles. Through utilizing high temporal and spatial resolution data inversion techniques we present here a …
Conjunction Observations of Energetic Oxygen Ions O+ Accumulated in the Sequential Flux Ropes in the High-Altitude Cusp
Dandouras, I.; Reme, H.; Wang, Chi +5 more
Conjunction observations of the magnetic field and plasma by Cluster and TC-1 at the dayside magnetosphere are presented to investigate the sequential flux ropes transferred from the low latitude boundary layer to the high-altitude cusp on 10 March 2004.Three sequential flux ropes originating from the dayside low latitude magnetopause are first de…
