Abstract: The extinction coefficients in UBV filters were determined using the 15cm reflector at Guwahati University Observatory, Jalukbari during January - March, 1994, January - March, 1995 with photometric observations. The extinction coefficient K lowerscript U, K lowerscript B, K lowerscript V have been found to vary between 0.58 - 0.66, 0.53 - 0.61, 0.45 - 0.48 respectively and their average values are obtained. A seasonal variation is expected. This is an important parameter for the site of the observatory. Measurement of the extinction coefficients for a longer period will be required for a reliable estimate of the parameter.
