Sun exploded in X-class flash
An intensely progressive large group of sunspots 2192 appeared on the eastern limb of the Sun. According to the Fedorov Institute of Applied Geophysics, on Sunday at 9:03 Moscow time there was a long (91 minute) outbreak of the highest class — X1.1.
Pulses of radiation in the ultraviolet and X-ray spectra suppressed short-wave radio communication on the visible side of the Earth, especially in Asia and Australia. A powerful explosion was probably accompanied by an ejection of coronal mass.

Meanwhile, the planet’s magnetic field has not yet calmed down after the magnetic storm that raged the day before. According to high-latitude stations, on Saturday, October 18, the geomagnetic field was strongly disturbed. There were many auroras.

Over the past 24 hours, the area of the group of spots 2192 has increased 6 times to 1240 MDPs (millionths of the visible hemisphere). For comparison, the sizes of the disks of the Earth and Jupiter are given in the photo of the solar coronagraph.
Geophysicists predict the preservation of high flare activity of the Sun with the probability of X-class flares. The sunspot 2192 gradually turns to Earth.
