A busy Space Weather Day today!
A minor (G1) geomagnetic storm is now in progress. Solar wind enhancements including a southward Bz component of the interplanetary magnetic field could help fuel things further. A reminder that a watch for moderate (G2) and strong (G3) conditions will also be in effect should things escalate further during the next 24-48 hours. Aurora sky watchers at middle to high latitudes should be alert once dark outside.
UPDATE: The Moderate (G2) Storm threshold was reached at 20:08 UTC (Aug 17). Visible aurora will be likely at middle to high latitudes once dark outside.
ALERT: Geomagnetic K-index of 6
Threshold Reached: 2022 Aug 17 2008 UTC
Synoptic Period: 1800-2100 UTC
Active Warning: Yes
NOAA Scale: G2 - Moderate
Eruptive flare activity around AR 3078 continues on Wednesday. An M2.0 solar flare was observed at 13:45 UTC (Aug 17). This looks to be responsible for a bright coronal mass ejection (CME) that so far is headed mostly south of the Sun-Earth line. A further update will be provided once complete cornagraph imagery is available.
