Authors Rohit Patil, S. B. Patil from D.Y.Patil COE,Kolhapur R. N. Ghodpage, M.F. Radar from Indian Institute of Geomagnetism, India has made use of Image processing for studying the Ionospheric Activities. This article submitted to IJSRD contains the study of ionosphere which plays the main role in HF transmission. The equatorial ionospheric plasma bubbles that occur at the low-latitude F-region of the ionosphere and the irregularities associated with them are responsible for several interference and sudden disruption of transionospheric radio propagation up to Giga Hertz frequency range, interfering with the communication systems, including the GPS. A CCD-based all-sky imager with 180° field-of-view is used to take photographs of all sky on clear, moonless nights, to study the F-region dynamics through the imaging with optical filter OI 630.0 nm oxygen emission line.

They concluded that main objective of this work is to post process the obtained images from the CCD camera by rectifying the distortions introduced and mitigating the consequences of the Van Rhijn effect and atmospheric extinction. These high-quality All-sky imager data can be used to investigate several key characteristics of the plasma depletion observed from low latitude ground based station.
