Earth is now under the influence of a stronger than expected coronal hole high speed stream (CH HSS). G2 (Moderate) geomagnetic storming has been observed and continued low-level storming is possible over the next 24 hours as Earth remains under the influence of
A high-speed solar wind stream from a geoeffective coronal hole is buffeting Earth's magnetic field and causing geomagnetic storms around the poles. The Bz component of the interplanetary magnetic field (IMF) is rotating between north and south pointing
A disturbance rippled through Earth’s magnetic field on Feb. 14th. On several occasions the sky was full of auroras from horizon to horizon, said photographer and aurora tour guide Chad Blakley of Abisko National Park, Sweden for Spaceweather.com.An update to the
As predicted by analysts at the Goddard Space Weather Lab, a coronal mass ejection (CME) hit Earth’s magnetic field at ~03:30 UT on Sept 17th. The impact was not strong. Nevertheless, the arrival of the CME could spark geomagnetic activity around the Arctic Circle.
High-latitude sky watchers should be alert for auroras. A G1-class (Kp=5) geomagnetic storm is in progress.NOAA Space Weather Scale for Geomagnetic StormsSolar windspeed:
