Abstract. A statistical study has been done on soft x-ray (SXR) flares, the data of which were collected by Geostationary Operational Environmental Satellites (GOES) during the period July 1993–June 1994. From the analysis different distribution functions were obtained empirically which give the number of SXR flares per unit interval of intensity and asymmetry in duration and angular interval of longitude. These distribution functions have been used for evaluating the center to limb variation of optical thickness for SXR flares.
