ESR/EISCAT - CLUSTER mode 1
ESR
EISCAT
CP-4-B (dual beam VHF or VHF/UHF - any chance of 3
klystrom operations allowing both?) use minimum elevations. All Fixed beams.
Particularly useful in cusp region at winter solstice when optical observations
of 630 nm and 557.7 nm aurora are possible. The optical instruments can define
transients and ESR be used to investigate emission profile. Also valuable in
TCV studies, where events are defined by magnetometers. In both cases events
allowed to pass through beam. Useful with low altitude satellite passes as time
in cusp is limited. Need Bz near zero, so optical cusp is overhead. Can
we use real time optical data from optical instruments on Svalbard to make
decisions? Also valuable on nightside for looking at transpolar arcs,
activations on open-closed boundary poleward of main substorm aurora, southward
drifting arcs in growth phase.
This mode could be considered for the following EISCAT/ESR configurations
with Cluster:
