Abstract: The heliographic longitudinal distribution of the daily soft X-ray flare index values is given for 1979 and 1980 years (Table 1). The soft X-ray flare index was determined from the daily continuous SMS-GOES profile of solar soft X-ray flux (0.1-0.8 nm), as published in Solar Geophysical Data. The left (right) columns of Table 1 comprise the 1979 (1980) daily data. The Eastern (E), Central (C) and Western (W) LDE-type flare indices, as well as a daily flare index computed from the impulsive-type (I) flares were so far published for the decreasing part of the 20-th solar cycle, as well as for the onset part of the 21-st solar cycle (from January 1, 1969 to December 31, 1980).
