Excerpt: “The strong solar activity in July continued into early August, but then faded away by mid-month. We recorded 68 classified flares in August, compared with 150 in July. There were however two X-class flares recorded, although they were rather late in the evening for the European signals. The background X-ray flux shown in the satellite data was also fairly high, so many of the smaller C-class flares were missed. Many of the stronger flares were also multiple-peaked again, giving plenty of unclassified SIDs.”
