[Regnum] A powerful M1.1 flare occurred on the Sun. This was reported on August 19 by the press service of the Institute of Applied Geophysics named after Academician E.K. Fedorov (Federal State Budgetary Institution "IPG").
“On August 19 at 07:39 Moscow time, an M1.1 flare lasting 50 minutes was recorded in the X-ray range in the sunspot group 4188 (S09E88),” the report says.
Moderate flare activity is expected in the next two days. Class X flares are not excluded.
Scientists noted that the geomagnetic field may be unstable, and the radiation situation may be undisturbed. Also, radio communications may deteriorate during the day.
Magnetic storm started on Earth due to coronal hole on the Sun

[Regnum] A magnetic storm has begun on Earth due to the action of a coronal hole on the Sun. This was reported on August 19 by the Solar Astronomy Laboratory of the Space Research Institute of the Russian Academy of Sciences.
"Judging by the explosive growth of the solar wind speed, the Earth has just flown headlong into a coronal hole. Let's see how strong the magnetosphere is," the scientists reported on their Telegram channel.
According to them, at the moment the magnetosphere is in the green zone.
Earlier it became known that magnetic storms on Earth could intensify to the red level by the end of the day. However, according to their forecasts, in the next 48 hours the geomagnetic activity index, which measures disturbances in the Earth's magnetic field, could move to the yellow and even red zones. There is also a possibility that the solar wind speed will approach the orange level.

Scientists warn of possible intensification of magnetic storms by the end of the day
Magnetic storms on Earth may intensify to the red level by the end of the day. This was reported on August 19 by specialists from the solar astronomy laboratory of the Space Research Institute of the Russian Academy of Sciences.
According to scientists, geomagnetic disturbances are expected within the next 48 hours.
“At the same time, observations are lagging far behind the forecast, and the speed values of 800-900 km/s expected by the morning are still nowhere to be seen,” experts noted on the Telegram channel.
Scientists noted that the geomagnetic activity index, which measures disturbances in the Earth's magnetic field, remains in the calm zone for now. However, they predict that it could move into the yellow and even red zones in the coming hours. There is also a possibility that the solar wind speed will approach the orange level.
