The continuation of the list of long-lasting SXR flares (LDE-type) from November 1991 to June 1992 is given in a computer-file form. The maximum values of the sunspot and H-alpha grouped solar flare numbers belong to the 21-st solar cycle (the second half of 1979). The 22-nd cycle displayed the highest CR decrease and LDE-type flare occurence of the last three solar cycles.
