ON THE PRECURSORS OF SOLAR FLARES IN SEPTEMBER 2017
Abstract and keywords
Abstract (English):
The X9.3 solar flare that occurred on September 6, 2017 is considered. The study of variations in the properties of small-scale fluctuations in the probability density of solar X-ray fluxes from the GEOS spacecraft made it possible to identify a set of events that repeat before the flare. A series of 1 to 8 precursors precedes the outbreak 20–70 hours before.
