- Pages: 98 -- 120
The daily soft X-ray flare index was determined from the daily continuous
profile of solar soft X-ray flux. In order to determine the heliographic
coordinates of Long Duration Events (LDEs) we exploited the fact that the soft
X-ray flare emission is uniquely tied with the occurrence of H-alpha flares.
The daily flare index is given in Tables 1 and 2. They contain the Eastern (E),
Central (C) and Western (W) indices of an LDE as well as a daily flare index
of the impulsive (I) flares, observed from January 1969 to December 1972.
