The minor (G1) geomagnetic storm threshold was reached at 19:51 UTC (May 4) thanks to a prolonged period of southward Bz. SolarHam.com

A quick M6.0 solar flare was just detected around AR 4420 at 22:57 UTC (Apr 26). Early indications are that this event was not eruptive, so a noteworthy CME is not expected.

NOAA/SWPC have issued a moderate (G2) geomagnetic storm watch for April 17th and 18th in response to an expected coronal hole stream. Aurora sky watchers especially at higher latitudes should be alert this weekend. SolarHam.com

Incoming CME detected at 15:04 UTC (Apr 3). Passage past Earth expected within the hour. SolarHam.com

AR 4409 nearing center disk continued to show signs of development in both size and magnetic complexity over the past 24 hours. The region is now producing frequent minor C-Flares and was also the source of an M1.3 flare at 07:56 UTC (Apr 3).

X1.5 solar flare with an Earth directed CME produced by AR 4405 this morning at 03:18 UTC. Moderate (G2) storm watch issued beginning Tuesday (Mar 31). SolarHam.com

A solar wind stream flowing from coronal hole #34 is expected to reach Earth by March 30th. NOAA/SWPC issued a minor (G1) geomagnetic storm watch for Monday.

Long duration M1.3 solar flare detected around AR 4405 peaking at 04:15 UTC (Mar 28). A CME is likely associated. Because the eruption site is near the SE limb, it should be directed mostly away from Earth. More to follow. SolarHam.com

Strong (G3) geomagnetic storm now in progress. Threshold was reached at 10:42 UTC (March 22). ALERT: Geomagnetic K-index of 7 Threshold Reached: 2026 Mar 22 1042 UTC Synoptic Period: 0900-1200 UTC Active Warning: Yes NOAA Scale: G3 - Strong

A Strong (G3) geomagnetic storm is currently in progress. Threshold reached at 23:28 UTC (Mar 20). SolarHam.com

A minor (G1) geomagnetic storm is currently in progress. A watch for moderate (G2) conditions is in effect until 06:00 UTC (Mar 21). The SWS increased to around 500 km/s and the IMF strength to 30 nT. Bz also tipping south. SolarHam.com

Halo CME emerging off the farside of the Sun on Friday. A number of returning sunspot regions are expected next week. SolarHam.com

The first CME that was expected to reach Earth today has yet to be detected and geomagnetic activity remains at quiet levels. The plasma cloud that left the Sun on March 16th may be running late or it could turn out to be a dud. I was initially not very impressed with the look of the CME, but perhaps we will get surprised. A further update will be provided should conditions change.
