Abstract : This paper investigates the intensity aspects of nightglow OI 630.0 nm emission obtained from all sky imager (ASI) at low latitude station Kolhapur (16.42ï‚°N, 74.2ï‚°E, and 10.6ï‚°N dip lat.), India. Herein we have taken average intensity of cropped images (5 Ã— 5 pixel size) of OI 630.0 nm, to study the nocturnal variations in intensity. The results show that when Milky Way Galaxy presents then the major enhancement occurred in intensity. The reason for this behavior may be associated with action of high energetic radiation from galaxy. However post-midnight enhancement in intensity of OI 630.0 nm emissions as result of the midnight temperature maximum (MTM) phenomenon, as anomalous behavior of neutral temperature during night in the F region has been reported from Indian and Brazilian sector by several investigators. An enhancement in intensity is important source of intermittence due the presence of the galaxy in the sky on observation nights. This work will help to develop the new theory related to ionosphere and extra terrestrial objects. Supporting data is necessary to find out possible mechanism for such events.
