Latest Space Weather News
Minor (G1) Storm in Progress
June 11, 2026 @ 20:50 UTC
A surprise geomagnetic storm (G1-Minor) is currently in progress thanks to a south pointing Bz/IMF component of the solar wind.

ALERT: Geomagnetic K-index of 5
Threshold Reached: 2026 Jun 11 2040 UTC
Synoptic Period: 1800-2100
Active Warning: YES
Noaa Scale: G1 - Minor

Long Duration C-Flare + CME
June 11, 2026 @ 01:45 UTC (UPDATED)
This long duration mid level C-Flare was observed around AR 4465 in the northeast quadrant peaking at 00:02 UTC (June 11). While this may not seem like much, coronal dimming is evident and a coronal mass ejection (CME) with a possible Earth directed component is associated. More to follow once a tracking model is available.

UPDATE: A minor (G1) geomagnetic storm watch was added beginning June 13th. The CME associated with the duration C6 flare appears to be heading mostly to the east with a glancing blow possible late on Saturday (UTC). High latitude sky watchers should be alert this weekend should local light and weather conditions allow.

ALERT: Type II Radio Emission
Begin Time: 2026 Jun 11 0013 UTC
Estimate Velocity: 918 km/s

Storm Watch Cancelled For Now
June 8, 2026 @ 22:20 UTC (UPDATED)
According to an update by NOAA/SWPC, the strong (G3) storm watch for today and moderate (G2) storm watch for Tuesday has been cancelled. As of this update, there is still no sign of the anticipated CME passing Earth. If a late CME passage is detected, I will provide a further update. For now, geomagnetic activity is at quiet levels.

Earth Facing Eruption + CME
June 6, 2026 @ 14:40 UTC (UPDATED)
A wide area of coronal dimming is evident this morning following an apparent eruption in the vicinity of AR 4461 located in the southeast quadrant. GOES solar X-Rays reached a peak of M1.8 at 14:00 UTC (June 6). The event is associated with a type II radio emission with an estimated velocity of 838 km/s. More to follow regarding a likely CME and if it is Earth directed. Image below by SDO/AIA.

UPDATE #2: A strong (G3) geomagnetic storm watch was issued beginning midday June 8th and into the 9th when the CME associated with this event is predicted to pass Earth.

CME Update:
An asymmetrical halo coronal mass ejection (CME) is leaving the Sun today following the eruption in the southeast quadrant. Although the mail bulk of plasma is heading southeast, there does appear to be an Earth directed component. An automated CME model by NASA is showing a passage past Earth by June 8th. Another round of geomagnetic storming may be possible. Stay tuned for more updates regarding this event.

Geomagnetic Storm Watch Continues
June 5, 2026 @ 12:50 UTC
Earth continues to pass through a multiple CME disturbance on Friday. After an initially weak impact very early this morning, solar wind data is looking a little more promising the past couple of hours. A secondary solar wind speed increase to around 650 km/s was observed, along with the Bz tipping south (-17 nT max). NOAA/SWPC are keeping a moderate (G2) to strong (G3) geomagnetic storm watch in place for the next 6 hours. Obviously not great timing for aurora sky watchers across Europe and North America.

Incoming CME Detected
June 5, 2026 @ 03:10 UTC (UPDATED)
Geomagnetic activity remains at quiet levels as an expected incoming CME is running late. The latest ACE EPAM data at 03:00 UTC (June 5) however is showing a sharp particle increase. This may be a sign that an interplanetary shockwave is approaching. I will continue to monitor the solar wind data and post any updates whenever necessary.

CME Detected: An incoming CME was detected at 04:31 UTC (June 5) by the ACE spacecraft and swept past Earth at 05:11 UTC. Initially the solar wind speed increased from 400 km/s to around 500-550 km/s with the Bz/IMF component pointing north. It is still early in the passage phase and fluctuations will be likely in the hours ahead. A geomagnetic storm watch remains in effect.

SUMMARY: Geomagnetic Sudden Impulse
