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
On February 10th there was filament eruption in the northern hemisphere that produced CME which traveled few days before reaching our magnetosphere on February 14. As magnetic disturbance rippled around the Arctic circle on February 14th, it opened a crack in our
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
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
After two-week long transit around the far side of the Sun, Sunspot 1402 has returned into view in the northeast quadrant. Sunspot 1402 is now re-numbered as Sunspot 1419. This region is smaller than it was before, after two weeks of decay. On January 27 it unleashed
Coronal mass ejection (CME) is seen in the latest images, as the result of a filament lifting off in the northern hemisphere. Geomagnetic field activity is expected to increase to unsettled to active levels, with high latitude minor storm intervals. It could produce
Explosion of dark magnetic filament occurs over the northeastern limb during the late hours of February 9th. Explosion generated a bright coronal mass ejection (CME) that is heading toward Venus as it seems. Fortunatelly, this CME is not Earth-directed. Sunspot
Solar activities intensified again yesterday with bright coronal mass ejection (CME) produced by M1 solar flare. Sunspot 1410 located in the northwest quadrant produced a moderate solar flare, reaching M1.0 at 20:00 UTC Monday afternoon. The flare was about an hour
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
