The first-ever high resolution 2-D maps of OI 630.0 nm dayglow obtained from equatorial latitudes clearly reveal the movement as a large-scale feature of the equatorial ionization anomaly (EIA). These also show the presence of wave-like features c

A meridional scanning OI 630.0-nm dayglow photometer was operated from Ahmedabad (17.2°N dip lat.) scanning a region towards the south in the upper atmosphere extending over ~5° in latitude from 10.2°N to 15.2°N dip latitude. From the spatial

Results from coordinated measurements of OI 630.0 nm dayglow intensities (centered on ∼220 km altitude), along with VHF (50 MHz) coherent backscatter returns from Thiruvananthapuram, a dip equatorial station in India, revealed that the temporal var
