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.
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.
During the same period, major storm levels were observed at high latitudes.
Geomagnetic field activity is expected to be at mostly quiet levels in the absence of any transient solar wind features. Recurrent coronal hole high speed streams are expected to bring unsettled to active conditions on August 5, 6 and 8, August 18-19, 21-23 and 31. Full article at the watchers
