Atomic Oxygen 630 nm and OH Airglows at Mt. Haleakala, Hawaii in February and November 1993
Temporal variations of the all-sky distribution of atomic oxygen 630 nm airglow intensity were observedatMt. Haleakala in Maui Island, Hawaii, to obtain informationonthe dynamics of <I>F</I> region plasma in the equatorial anomaly region. All-sky intensity distribution of the hydroxyl OH(7, 2) band airglow originating from the mesopause region was simultaneously observed to seek any relationship between the dynamical variations of <I>F</I> region plasma and the disturbance in the lower atmosphere. The results of our preliminary analyses of the data obtained in February and November 1993 show that there is no definite correlation in the patterns of all-sky intensity distribution between atomic oxygen 630 nm and OH(7, 2) band airglows in both geomagnetically disturbed and quiet nights. The all-sky intensity pattern of 630 nm is found to be modified during a geomagnetic storm, while that of OH(7, 2) band varies independently of geomagnetic activity.
