| Zusammenfassung |
| The Earth’s ring current and how it responds
to varying interplanetary conditions is described and an account
provided of the production of Energetic Neutral Atoms
(ENAs) in the geo-corona. Also, the potential to remotely
monitor, on a global scale, the temporal and spatial evolution
of magnetospheric plasma populations through analysing
ENA images recorded during magnetic storms/substorms is
indicated. A technical account of the Energetic NeUtral
Atom Detector Unit NUADU aboard China’s TC-2 mission
(measurement range 45–>158 keV) follows, together with
an account of the scientific objectives of NUADU, both in
stand-alone mode and in the context of multi-point imaging.
Low altitude ENA emissions recorded by NUADU during
south polar passages of TC-2 at the time of a moderate
magnetic storm in September 2004, as well as bright ring
current emissions recorded in November 2004 during a major
geomagnetic storm, are presented and discussed in the
context of various, accompanying, terrestrial disturbances.
Also, ENA observations of the November 2004 ring current
imaged simultaneously by TC-2/NUADU and by IMAGE/
HENA (viewing, respectively, from the Northern and
Southern Hemispheres), are compared. |
