Specialists from the Institute of Applied Geophysics (IAG) have recorded two class M solar flares. Scientists suggest that these flares may lead to a magnetic storm on Earth from November 30 to December 1.
"In the X-ray range, a flare of M3.4 with a duration of 28 minutes and a flare of M9.8 with a duration of 34 minutes were registered, accompanied by a burst of radio emission of the II spectral type and a coronal mass ejection containing a geo-effective component. Disturbance of the geomagnetic field is expected on November 30 - December 1," quoted the IAG heliogeophysical service by TASS.
Over the next 27 days, the IAG predicts solar activity ranging from low to moderate, with the possibility of X-class flares.
In July, NASA reported a record number of sunspots: researchers discovered 160 spots on the Sun in June, the highest number in the last twenty years. The current solar cycle, the 25th since registration began, is gaining intensity much faster than predicted by NASA and the U.S. National Oceanic and Atmospheric Administration (NOAA). This situation raises concerns about an increase in the number of solar storms.
In March, NASA's Solar Dynamics Observatory recorded an X-class flare with an index of X1.2. X-class flares occur less frequently than flares of other classes and have a peak intensity exceeding 10^−4 W/m². On February 17, 2023, the observatory detected a powerful X2.28 flare. Both events led to a disruption in radio communication.
