Abstract:	A few methods of estimating Fried's parameter (r 0) from specklegrams of solar features are described. Some of these methods were used to estimate r 0 for the speckle data obtained from Kodaikanal Observatory (KO), Uttar Pradesh State Observatory (UPSO) and Udaipur Solar Observatory (USO). The average value of r 0 was found to be 3 cm at USO and UPSO during our observations. At KO, values of r 0 ranging from 6 to 10 cm were estimated.
