High resolution Fabry-Perot interferometer (FPI) winter night observations with clear skies are discussed. A standard FPI observed the OI 630 nm airglow/auroral emission to produce wind and temperature data near 240 km altitude. A triple-etalon FPI made high resolution studies of band spectra and extended the observing period into bright twilight. A prototype Doppler imaging system was successfully tested. Highly disturbed thermospheric conditions were recorded, including horizontal winds in excess of 850 m/sec and vertical winds of over 100 m/sec during strong geomagnetic substorms.
