THREE DAYS, THREE X-FLARES: Today (Oct. 26), for the third day in a row, Earth-orbiting satellites detected an X-class solar flare. The X2-category blast came from giant sunspot AR2192, shown here in a Sunday morning sunrise photo from Jean-Baptiste Feldmann of Nuits-Saint-Georges, France: Recapping the rapid-fire flares: There was an X3 on Oct. 24th (2140 UT), an X1 on Oct 25th (1709 UT), and an X2 on Oct. 22nd (1059 UT). All three of these explosions produced strong HF radio blackouts over the dayside of Earth. In each case, communications were disturbed over a wide area for approximately one hour. Such blackouts may be noticed by amateur radio operators, aviators, and mariners.
