Abstract

This paper reports the airglow observations in the extreme solar minimum period of 2007-2008 over low-latitude and equatorial regions. The observations are carried out using Imager of Sprites and Upper Atmospheric Lightning (ISUAL), onboard FORMOSAT-2 satellite. The ISUAL takes limb images of the emissions centered at 630.0 nm, viewing towards the right when the satellite is in the ascending orbit. The images are analysed to investigate the airglow intensity in the solar minimum years and also the latitudinal enhancement peaks in the emission. The results indicate that in the quiet conditions during 2007-2008, the seasonal variations are less pronounced.
