Full Sky Alberta Aurora Possible, June 12/13

Cause: Anticipated arrival of Coronal Hole High Speed Stream (CH HSS) Coronal Mass Ejections (CME) from June 9 and 11

Geomagnetic field conditions are expected to reach G1 (Minor) geomagnetic storming on 12 June under anticipated -CH HSS effects. G2 (Moderate) geomagnetic storming levels are likely on 13 June due to the persistence of the high-speed stream and the arrival of the disturbances caused by the CMEs that left the Sun on 09 and 11 June. G1 (Minor) levels are likely on 14 June, as the CMEs effects wane.
