Weak magnetic storm hits Earth on Aug 18
The first August magnetic storm of G1 (weak) to G2 (moderate) level began on Earth on August 2.
Consensus
- A magnetic storm of level G1 occurred on Earth on August 18.
- The geomagnetic activity was caused by a fast solar wind from a coronal hole.
- The storm was short-lived, with the magnetic field expected to return to a weakly disturbed state by midday Moscow time.
- Full stabilization of the geomagnetic field may take two to three days.
- August has seen unusually high geomagnetic activity, with three magnetic storms recorded in 18 days.
- The current geomagnetic disturbances are not expected to exceed level G2.
- There is no sign of decreasing geomagnetic activity at this time.
Points of divergence
- The probability of moderate and weak magnetic storms is about 86%, and the probability of strong solar flares (M and X classes) is around 40%. — vesti
- The probability of magnetic storms on August 19 is estimated at 56%, with geomagnetic disturbances expected to continue into Thursday. — fontanka
- The solar wind parameters remained at low values, making it unclear how the storm was triggered. — vm
- The first magnetic storm of August occurred on August 2, with a strength between G1 and G2. — vedomosti
