A site with optimum atmospheric properties is very essential for the successful implementation of NLST. One of the primary criteria for site selection is presence of good seeing over long periods of time with clear skies. In this Poster, we present the diurnal variation of solar seeing measured in terms of Fried’s parameter (r0) obtained by Solar Differential Image Motion Monitor (SDIMM) instrument installed near Pangong Tso Lake in Merak located at an altitude of 4258 m. The requirement of continuous good seeing is a key factor for adaptive optics to function. Therefore, we have derived statistics for annual sunshine hours, annual hours with Fried’s parameter r0 larger than 7 cm and 12 cm at 500 nm wavelength and number of blocks having continuous spell of 1, 2 and 4 hour duration of good seeing, larger than 7 cm. We also present the comparison of these parameters with the other sites which hosts the large solar telescopes. |
