At low latitudes, in the nocturnal variation of 6300 Å night airglow, quite often increases in intensity followed by decreases are observed. Such 6300 Å enhancements are broadly classified under the two heads as 'pre-midnight' and 'post-midnight' enhancements, depending on their time of occurrence. From a large amount of data obtained at Mt. Abu, India, with three photoelectric photometers, these enhancements are studied and the dynamics of the ionosphere in low latitudes during those hours is investigated. It is shown that vertical downward movements of electrons is one of the main causes for these enhancements.
