1.0 Introduction and Scientific Objectives

We propose to investigate the ionospheric response to the ionospheric Alfvn resonator

near an auroral arc with a sounding rocket experiment, the Poker Flat Incoherent Scatter Radar

(PFISR), and auroral imaging from Ft. Yukon, Alaska. The proposed launch site is the Poker Flat

Research Range (PFRR). PFISR will be used to monitor ion and electron density and tempera-ture under the rocket trajectory for comparison with the sounding rocket data and to determine

the launch conditions. The MICA (Magnetosphere-Ionosphere Coupling in the Alfvn resonator)

sounding rocket will measure ion temperature and density, electron temperature and density,

electron precipitation, ion upflow, convection and ULF electric fields, magnetic fields from

which field-aligned current (FAC) can be inferred, and plasma waves. The objectives of the ex-

periment are to investigate the role of active ionospheric feedback in the development of large

amplitude and small scale electromagnetic waves and density depletions in the low altitude (Altitude switch->+28H) analog power input16 TEST Pulse amp test analog power inputreturns with ? may be omitted on NASA side
