Full Sky Alberta Aurora Possible Evening of March 24
50% probability of Full Sky Alberta Aurora for March 24 +/-24hrs
Cause: Coronal Mass Ejection (CME) associated with the Mar 23 solar flare.
Quiet to active conditions are expected for the second half of 23 Mar as CME effects diminish. Quiet to active levels are expected on 24 Mar. By late on 24 Mar to early on 25 Mar, combined activity from a CH HSS and the 23 Mar CME are likely to cause G1-G2 (Minor-Moderate), with a chance for G3 (Strong) geomagnetic storm.
