| 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. |
