Geomagnetic Disturbance Alert
23rd August 2013
British Geological Survey
Two Earth directed coronal mass ejections (CME) both associated with solar filament eruptions left from the Sun on the 20th and 21st August. The first shock arrival is expected late on August 23rd, with the second anticipated on the 24th.
The combined effects of these two CMEs and a high speed solar wind stream from a coronal hole could cause a geomagnetic storm thus increasing the chance of viewing the aurora over the weekend.
