Science Questions:space vs time
(1) Does dynamic aurora move with respect to the background ionosphere? How much? Does it matter?
(2) What is the spatial (as opposed to temporal)variation of auroral parameters like B and E?What does this mean for theories of energy transfer?
(3) Alfven waves carry disturbances and changes down to and through the auroral zone, giving us structured anddancing aurora. They are pretty: do they matter? Are these structures significant for magnetosphere/ionosphere coupling? Do direct observations of these motions validate
theories and models?
PoGOLite is a balloon-borne experiment which stands to open a new observational window on the Universe through measurements of the polarisation of gamma-rays in the energy range 25 - 80 keV from compact astrophysical objects, such as pulsars, and accreting black holes. Thepolarisation is reconstructed using the modulation of Compton scattering angles in the segmented sensitive volume of the instrument composed of plastic scintillators.
