Full Sky Alberta Aurora Possible, May 14 & 15
40% and 30% probability of Full Sky Alberta Aurora, evening of May 14 & 15 respectively +/-24hrs
Cause: Anticipated arrival of the May 10 Coronal Mass Ejection (CME) and Coronal Hole High Speed Stream (CH HSS) influences.
The geomagnetic field is expected to reach active conditions on 14 May, due to the glancing influences of the 10 May CME event and/or effects of a positive polarity CH HSS. G2 (Moderate) storming conditions are likely on 15 May due to the anticipated arrival of a negative polarity CH HSS near Earth. Active to G1 (Minor) storm levels are likely to prevail on 16 May due to lingering CH HSS influences.
