Simultaneous nightglow and Na lidar observations made at Arecibo during the AIDA-89 campaign are reported from between 0000 and 0530 LT on 6 April and 9 April 1989. On 9 April, the observations are consistent with the presence of a large-amplitude 8.5 km vertical wavelength, 4 h period wave propagating through the 85-91 km region. A lower amplitude 80 min period wave is also observed. The results imply that the O2 atmospheric band intensity peaked near 91 km while the OH Meinel (6,2) band intensity peaked near 85 km. The integrated Na abundance from 87 to 89 (90-92) km correlates well with the OH Meinel (O2 atmospheric) band intensity. On 5-6 April, the OH Meinel and O2 atmospheric band intensities are not well correlated. The OH Meinel intensity is correlated with the integrated Na abundance from 86 to 88 km. Both the Na and OH measurements reveal the presence of an approximately 1 h period wave.
