We report the first velocity resolved sodium 5889.950 Å line profile observations of the lunar sodium tail observed in the anti-lunar direction near new Moon. These observations were made on 29 March 2006, 27 April 2006 and 28 April 2006 from Pine Bluff (WI) observatory with a double etalon Fabry-Perot spectrometer at a resolving power of ∼80,000. The observations were made within 2–14 hours from new Moon, pointing near the anti-lunar point. The average observed radial velocity of the lunar sodium tail in the vicinity of the anti-lunar point for the three nights reported was 12.4 km s−1 (from …

The thermospheric midnight temperature maxi-
mum (MTM) is a highly variable, but persistent, large scale
neutral temperature enhancement which occurs at low lati-
tudes. Its occurrence can impact many fundamental upper
atmospheric parameters such as pressure, density, neutral
winds, neutral density, and F-region plasma. Although the
MTM has been the focus of several investigations employ-
ing various instrumentation including photometers, satellites,
and Fabry-Perot interferometers, limited knowledge exists
regarding the latitude extent of its influence on the upper at-
mosphere. This is largely due to observational limitations
which confined the collective geographic range to latitudes
within ±23◦. This paper investigates the …
