X1.0 / M7.3 Flare + Earth Directed CME Confirmed（该Full Halo CME最后被确认为太阳背面活动区抛射）
June 1, 2024 @ 19:55 UTC (UPDATED)
Active sunspot region 3697 (ex 3664) continues to produce strong solar flares. The latest event was an impulsive X1.0 solar flare at 18:36 UTC (6/1/2024). This was quickly followed by a long duration M7.3 event at 19:40 UTC. The M7 flare is responsible for an asymmetric halo coronal mass ejection (CME) that appears to be Earth directed. A passage past our planet will be possible within 48-72 hours. Geomagnetic storming may be possible by Monday or Tuesday. Further updates will be added on SolarHam.com regarding a tracking model once one is available.


X1.0 / M7.3 Flare + CME Confirmed（该Full Halo CME最后被确认为太阳背面活动区抛射）
June 1, 2024 @ 19:55 UTC
Solar X-Rays peaked at M7.3 at 19:40 UTC (Jun 1) following an initial X1.0 peak a little earlier. Coronal dimming is evident to the north of AR 3697 meaning a coronal mass ejection (CME) might be associated. More to follow.



CME Update: Updated imagery following the M7 eruption this evening is now starting to come in. Although hard to tell by the image below, an asymmetric halo CME is associated and appears to have an Earth directed component. A type II radio emission with an estimated velocity of 681 km/s was recorded. A passage past Earth will be possible within 72 hours. More to follow.

A type II radio emission with an estimated velocity of 681 km/s was recorded. A passage past Earth will be possible within 72 hours and could lead to at least a minor (G1) geomagnetic storm. More to follow.

Halo CME Update
June 2, 2024 @ 13:10 UTC
The latest NOAA/SWPC update explains that the halo CME observed soon after the long duration M7 solar flare may actually be related to farsided activity and not Earth directed. While some plasma appears to have released following the Earth facing event, the halo signature may be unrelated. If so, the prospects for geomagnetic storming just diminished significantly. More to follow once any other updates are officially announced.

Reaching New Highs
June 2, 2024 @ 10:00 UTC
It goes without saying that May 2024 was a great month on the Sun. Large sunspots and large solar flares dominated our attention. We also reached a new high for both the solar flux index and sunspot number count for solar cycle 25. The sunspot number average for May 2024 is 171.7. This is the highest count since September 2002 during cycle 23. The solar flux index average for last month is 187.7, also a new high for the current solar cycle.

Minor (G1) Storm Watch
June 2, 2024 @ 21:10 UTC
A minor (G1) geomagnetic storm watch was added for June 4th. An eruption following an M7.3 solar flare on Saturday apparently ejected enough material to possibly pass Earth and generate a storm. Aurora sky watchers at higher latitudes should be alert beginning Monday night and into Tuesday.
