The approaching peak of Solar Cycle 25 has led to the observation of massive coronary holes on the Sun's surface. These holes, similar to sunspots but with distinct differences, are linked to solar storms and may increase the probability of solar flares in the coming days. Space agencies and meteorological organizations are closely monitoring

Finally a relatively quiet weekend conditions on the #amateurradio #hamradio bands. 7 #sunspot regions with less than triple digit #sunspots. Looks like #coronalholes have a slight potential of producing a minor #geomagneticstorm. #spaceweather #solarcycle25
