A solar filament was observed lifting off the Sun's northeastern quadrant beginning at approximately 04:45 UTC on November 25, 2017.
An associated weak Coronal Mass Ejection (CME) was observed in SOHO/LASCO C2 and C3 imagery and the analysis shows a potential glancing blow arriving at Earth on November 29.

Another filament is anchored in the southwest filament and is rotating away from the geoeffective position.
Solar activity was at very low levels today and is expected to remain like that, with just a slight chance for C-class flares over the next three days
There is only one numbered sunspot region on the Earth side of the Sun – AR 2689. Although this region showed signs of growth over the past 24 hours, it lacked significant flare activity.
The greater than 2 MeV electron flux was at normal to moderate levels over the past 24 hours, with a peak flux of 309 pfu observed at 15:05 UTC on November 25.
Solar wind parameters are currently at ambient background conditions and expected to become enhanced on November 27 and 28 as a negative polarity coronal hole high speed stream (CH HSS) becomes geoeffective.
Unsettled to active geomagnetic field levels are expected on November 27 and 28 due to the onset of negative polarity CH HSS.
