In this talk I about the observational facilities used in the past to take the images of the sun in continuum and some prominent absorption line such as H-alpha and Ca-K. Their development with time. Then I discuss ground base high spatial and spectral resolution recent facilities in operation now a days. The space base instruments operating in the UV, EUV and X-rays are also explained in brief. Then I describe the future ground base and space base facilities such as 4m solar telescope ,DKIST ; space base coronagraph ADITYA-1 in brief. This talk is also preliminary in nature.
Prof. Jagdev Singh has long association with ARIES earlier UPSO, since 1988 when the planning and execution for the first astronomical expedition to Antractica was started. Lead the first astronomical expedition, 3 member team consisting to Indian station in Antarctica in 1989. 1.He did his Ph. D. With Dr. M K V Vainu Bappu a well known astronomer in the year 1984 using the data obtained by him during the total solar eclipses in 1980 & 1983. 2.Planned and successfully executed 10 expeditions to make observations of the solar corona during the total solar eclipses of the Sun. 3.
