A geomagnetic storm, the first of August and the sixth of the summer season, began on Earth on August 2, triggered by a solar plasma ejection that reached Earth around 14:30 MSK. The storm's intensity reached a moderate G2 level and lasted between 4 to 9 hours.
Consensus
- A geomagnetic storm began on Earth on August 2.
- The storm is the first of August and the sixth of summer.
- The event was caused by a solar plasma ejection that reached Earth on August 2.
- The storm's intensity is between G1 (weak) and G2 (moderate).
- The storm lasted no more than 4–6 hours, with one source suggesting up to 9 hours.
- The event was reported by the Laboratory of Solar Astronomy at the IKI RAS.
- The storm was predicted in advance on the morning of August 2.
Points of divergence
- The solar plasma ejection reached Earth at approximately 14:30 MSK, but the geomagnetic disturbance only reached storm level recently, less than an hour before the report. — vedomosti
- The geomagnetic disturbance intensified to a stable G2 level by 21:00 MSK, after initially being in the G1–G2 range. — fontanka
- The total duration of the storm, from start to complete dissipation, is expected to be 6–9 hours. — fontanka
- A forecast for a moderate-level geomagnetic storm on August 2 was issued by Mikhail Leus of the 'Fobos' weather center the day before, citing a coronal mass ejection from July 30. — vm
- Scientists observed signs of the destruction of an unnamed comet on June 30, which has no name or catalog number. — vedomosti
