On July 4, a powerful magnetic storm is occurring on Earth—the second strongest of the year—according to the Solar Astrophysics Laboratory of the Institute for Cosmic Research of the Russian Academy of Sciences (IKI RAS). On an annual scale, this storm ranks as the second most intense after the very large G4.67 event from January 19–21 and the March 21-level G3 storm.
Consensus
- A strong geomagnetic storm began on July 4, delayed by one day from the forecast.
- The storm reached level G3.33 and was the second strongest of the year after a January event at level G4.67.
- Despite large sunspot groups on the Sun, no major solar eruptions had occurred as of the reports.
- The geomagnetic storm was caused by solar mass ejections and changes in the interplanetary magnetic field.
Points of divergence
- A powerful solar flare classified as M-class, lasting 70 minutes, occurred on May 7, with a video recording published by the Laboratory of Solar Astronomy at IKI RAS. — vm
- The geomagnetic storm reached its peak in the morning and calmed to slightly below G2 by noon on July 4. — fontanka
- The decisive turning point occurred around midnight when solar wind parameters rapidly increased and the sign of the interplanetary magnetic field changed abruptly. — vesti
