The Watchers - by Adonai - August 5, 2013

During last 24 hours solar wind stream buffeted Earth's magnetic field causing geomagnetic storms around the poles. Geomagnetic conditions were short lived reaching G1 - Minor geomagnetic storm levels (Kp=5). At those levels weak power grid fluctuations can occur, minor impact on satellite operations is possible, migratory animals are affected at this and higher levels and aurora is commonly visible at high latitudes.

At about 05:13 UTC on August 4, Phi angle became positive (away) and total field, temperature and wind speed began to rise. Wind speed rose from 350 km/s to a maximum of 586 km/s at 23:00 UTC.​

The Bz component turned mostly southward for several hours and reached -13 nT by 20:25 UTC. This sequence of events brought unsettled levels of activity and a single period of minor storm conditions between 15-18 UTC.
