Geomagnetic storming expected to continue over the next two days

Geomagnetic storm reaching G2-Moderate levels has been observed on August 27, 2015, mostly due to effects of August 22 CME that arrived late on August 25. This activity is expected to slightly wane throughout the day, but active levels are again expected later in the da
