A large plasma cloud, formed as a result of a powerful solar flare, will reach Earth on June 1 at about 16:00 Moscow time. This was reported by the Solar Astronomy Laboratory of the Institute of Space Research and the Institute of Solar-Terrestrial Physics of the Russian Academy of Sciences.
The M8.2 level flare occurred at 03:05 Moscow time on Saturday in active region No. 4100. According to scientists' calculations, the mass ejection is moving at an exceptionally high speed - about 1200 kilometers per second. It will take the plasma about 35 hours to cover the distance of 150 million kilometers separating the Sun and the Earth.
Approximately 20–30 minutes before reaching Earth, the cloud will first hit a number of spacecraft located at the Lagrange point L1 — 1.5 million kilometers closer to the Sun. This zone includes the SoHO spacecraft, equipped with LASCO telescopes. Data from these satellites will provide timely warning and assessment of the potential impact on orbital systems located near Earth.
