Some results of whistler and VHF scintillation observations at Agra

179-182Results of whistler observations for the period Dec. 1989-Mar. 1991 and VHF scintillation observations for the period Jan. 1991-Mar. 1991 at the low latitude ground station of Agra are presented. It is shown that whistler activity at this station is very rare and sporadic. Large whistler activities have been observed at two occasions only, during fourteen months of observations. Some new results include the observations of higher harmonics of tweeks, daytime whistlers and daytime discrete chorus emissions for the first time in a low latitude ground station in India. The VHF scintillations at 244.168 MHz from FLEETSAT are recorded both during night and daytimes and their temporal variation of occurrence number and association with spread-F and sporadic-E irregularities are discussed
