A Forecast Watch for NOAA Scale G2 (moderate) Geomagnetic Storm conditions has been issued for 12 September, as the result of the coronal mass ejection associated with the M4 flare observed early on September 9th. The arrival of the plasma cloud at Earth’s magnetosphere is forecast for early on the 12th. G1 (minor) conditions are forecast to persist into 13 September. Displayed here is an ENLIL model depiction of the plasma cloud with a component flanking towards Earth.
