AB: During October and November, 2003, several major geomagnetic storms occurred. Using an array of Michelson interferometers, the effects of these storms on mesospheric hydroxyl and atmospheric temperature could be observed at high latitudes in both the northern and southern hemispheres. Data will be presented from the observatories at Ny Alesund, Spitzbergen; Onsala Sweden; and Rothera, Antarctica showing the effects of these storms on the hydroxyl emission and the atmospheric temperature. The large geomagnetic differences in the stations as well as the seasonal offset allow the effects of the storms to be assessed under a variety of conditions, and conclusions regarding the direct precipitation effects versus longer term heating will be presented.
