A fast-moving stream of solar wind is buffeting Earth's magnetic field

A fast-moving stream of solar wind is buffeting Earth's magnetic field. The combined effect of this stream plus a CME expected to arrive on June 24th has prompted NOAA forecasters to declare a 30% to 35% chance of geomagnetic storms during the next 24 hours. High-latitude sky watchers should be alert for auroras. (SpaceWeather)

Today is the day that a Coronal Mass Ejection (CME) may sweep past earth and trigger minor geomagnetic storming at very high latitudes. This slow moving cloud was caused by a long duration C7.7 flare around Sunspot 1236 earlier in the week. Be on the lookout for aurora if you are high in latitude.

The geomagnetic field is expected to be active with a chance for minor storm periods at mid-latitudes and isolated major storm periods at high latitudes for tomorrow (24 June). This activity is expected as a response to the arrival of the halo CME observed on 21 June. Conditions are expected to decrease to unsettled to active levels for the second day (25 June), and quiet to unsettled levels for the third day (26 June).




Is there connection with recent seismic activity along Alaska Peninsula and Solomon islands!?
