Mesopause Winds and OH Intensities at Mid-Latitudes-Fabry-Perot Interferometer Observations of the OH Emission at 8430 A from Bear Lake Observatory
Abstract
Observations were made from Bear Lake Observatory using an Imaging- Fabry-Perot Interferometer. Neutral winds were derived from the Doppler shift to the emission line, and relative intensity was also analyzed. Results presented are from the period between December 1991 and March 1992. The 8430 A OH data showed remarkable day-to-day variability in the wind pattern. Diurnal, semidiurnal, and terdiurnal tidal components all appeared at some point during the observing period with no consistent regularity. The OH intensities showed the presence of gravity wave activity with discernible period down to approximately 3 hours. The 6300 AO(1D) wind and intensity observations showed a high degree of magnetic activity which correlated positively with Kp and Ap indices. We noted a definite presence of auroral and SAR-arc activity almost nightly on nights when the 6300 A O(1D) emission was observed.
