A disturbance is rippling through Earth’s polar magnetic field on March 1st. Bright auroras have been sighted in Sweden and Finland. Rob Stammes of the Polar Light Center in Lofoten reports about magnetometer needles start to swing. This magnetic storm came as a
A CME impact followed by a gusty solar wind stream have combined to produce bright lights around the Arctic Circle on Feb. 26-29. Arctic sky watchers should be on alert for more auroras tonight. The green flash, the fleeting emerald light that sometimes appears
A CME hit Earth’s magnetic field on Feb. 26th at 21:00 UTC. Brief outburst subsided before it reached geomagnetic storm levels. A geomagnetic sudden impulse was detected by the Boulder station at 21:41 UTC. Maximum levels of planetary Kp index was listed as 4, just
A CME hit Earth’s magnetic field on Feb. 26th at ~2100 UTC. The impact was weak and does not appear set to cause a strong geomagnetic storm according to SpaceWeather. A solar wind increase to near 550 km/s was detected by the ACE Spacecraft around 20:50 UTC. A
A Coronal Mass Ejection (CME) is seen in the latest STEREO Ahead COR2 images on Thursday morning, and the source appears to be a filament channel eruption near region 1419 in the northwest quadrant. After a close look, the expanding cloud appears to be directed mostly
An expected solar wind stream hit Earth’s magnetic field during the waning hours of Saturday, Feb. 18th producing bright auroras all the way down into several US states including Wisconsin, Michigan, North Dakota, and Minnesota. The Bz is pointing South at times
The expected CME impact sparked aurora lights around the Arctic Circle on Feb. 14th. The display was probably caused by a CME, launched from the sun on Feb. 10th. Solar wind poured in and fueled a G1-class geomagnetic storm (Kp index was at level 5). Our
Earth passed through a minor solar wind stream on Feb. 4-5. The weak impact of the solar wind was just enough to spark auroras around parts of the Arctic Circle. The effects of the solar wind are subsiding, and the auroras might disappear into the moonlight for the
The anticipated geomagnetic storm caused by Monday’s M8.7 solar flare and Tuesday’s coronal mass ejection (CME) impact is over. The aurora watch has been cancelled today for all but the highest latitudes around the Arctic Circle but a dazzling display of aur
A coronal mass ejection (CME) hit Earth’s magnetic field at 06:17 UTC on January 23, 2012 and produce geomagnetic storm (Kp5/G1 Level geomagnetic storm is currently in progress) and ongoing auroras around polar cycle. According to analysts at the Goddard Space Weather
