Effects Of Solar And Lunar Eclipse On Ionosphere Near The Crest Of Equatorial Ionization Anomaly Region Bhopal

In the present paper effects of solar and lunar eclipse on ionosphere near the crest of equatorial ionization anomaly region Bhopal (23.2 degree N, 77.6 degree E) have been studied .For present study two sets of consequent solar and lunar eclipse,which occurred in the year of 2014,have been chosen. As a fact solar eclipse always occurs about two weeks before or after a lunar eclipse. Our objective is to study the variation in TEC,amplitude scintillation indexS4 and interplanetary parameters during the eclipses.
