From the second half of the day on June 27, 2025, the geomagnetic situation on Earth began to stabilize. This happened after weak G1-level storms caused by a coronal hole, according to the Solar Astronomy Laboratory of the Institute for Space Research (IKI) and the Institute of Solar-Terrestrial Physics (ISZF).
The still high speed of the solar wind, which remains at 700-800 km/s throughout the day, i.e., twice as high as normal, prevents us from announcing the official end of the event. Except for this (and maybe the temperature), the parameters of the near-Earth plasma have returned to normal. Calculations show that the speed should also return to normal by tomorrow morning, but some tension will remain until then.
According to scientists' forecasts, after the end of the influence of the coronal hole, a "dead season" will come on the Sun. Because no more activity is observed.
Earlier www1.ru reported that a coronal hole on the Sun caused magnetic storms on Earth on Friday.
