Long duration M1.9 flare detected in the vicinity of AR 4992. A CME will likely be associated and directed mostly to the west. A further update regarding a possible Earth directed component will follow if necessary. SolarHam.com

A minor (G1) geomagnetic storm is currently in progress thanks to an enhanced coronal hole stream moving past Earth. A watch for moderate (G2) conditions is in effect until 23:59 UTC (July 23). SolarHam.com
This nice looking M4.0 solar flare was just detected around AR 4482 peaking at 14:19 UTC (July 7). More details to following regarding a possible CME. SolarHam.com
X1.3 solar flare detected at 20:41 UTC (July 4th). The source is a new region turning into view from off the east limb. SolarHam.com
Strong (G3) geomagnetic storm watch now in effect. Solar wind speed currently 606 km/s and Bz/IMF remains pointed south. SolarHam.com
A moderate (G2) geomagnetic storm is now in progress. SWS remains near 600 km/s and the Bz component has been pointing sharply south at times. Aurora sky watchers, especially at higher latitudes should be alert if local light and weather conditions allow.
A minor (G1) geomagnetic storm is currently in progress. The SWS increased to around 600 km/s and the Bz/IMF component is pointing south. Moderate (G2) conditions also possible. SolarHam.com
An M6.7 solar flare is currently in progress around AR 4479 with a peak flux time at 18:11 UTC (July 3). More to follow if a coronal mass ejection (CME) is associated with this event. Image by GOES SUVI.
The CME associated with the X1.1 solar flare on June 30th is now arriving. A passage past Earth is expected within the hour. solarham.com
M8.5 solar flare detected around AR 4478 @ 23:09 UTC. The flare itself was fairly rapid, so a noteworthy CME will likely not be associated with this event. SolarHam.com
A minor (G1) geomagnetic storm is currently in progress following a CME passage earlier today. ALERT: Geomagnetic K-index of 5 Threshold Reached: 2026 Jun 30 2027 UTC Synoptic Period: 1800-2100 Active Warning: YES Noaa Scale: G1 - Minor
A solar flare reaching above the M5 level is currently in progress around AR 4475 in the southwest quadrant. More to follow.
A moderately strong solar flare measuring M6.9 was detected around AR 4473 at 19:29 UTC (June 21). It does not appear that a large CME will be associated, however a further update will be provided once new coronagraph imagery is available.
Solar activity increases further with this M2.6 solar flare detected around AR 4473 at 02:46 UTC (June 21). A further update will be provided if any sort of CME is associated with this event. SolarHam.com
What appears to be a shock passage was just detected by the ACE spacecraft at 09:56 UTC (June 13). This is likely the CME observed leaving the Sun on 6/11 arriving a little later than predicted. The solar wind speed increased from around 570 km/s to currently near 650 km/s.
Eruption this morning in vicinity of AR 4461 produced a CME that is now emerging. More to follow regarding a possible Earth directed component. SolarHam.com
Incoming CME detected at 04:31 UTC (June 5). The solar wind speed increased from 400 km/s to currently just above 550 km/s. A passage past Earth is expected within the next hour. SolarHam.com
Strong (G3) geomagnetic storm watch in effect for June 4-5 due to at least two CMEs predicted to combine for an impact. SolarHam.com
A solar flare measuring M9.3 was detected around Earth facing sunspot region 4455 peaking at 01:36 UTC (June 3). A further update will be provided if a CME is associated with this event. So far it appears that an eruption with this event would likely be minor. More to follow.
M1.9 solar flare detected around AR 4436 at 16:12 UTC (May 16). Coronal dimming already evident meaning a CME will be produced. A further update will be provided once updated imagery becomes available. SolarHam.com
A moderate (G2) geomagnetic storm is currently in progress. Aurora sky watchers should remain alert once dark outside. SolarHam.com
AR 4436 erupted with an M5.7 solar flare at 13:39 UTC (May 10). More to follow regarding a potential CME. solarham.com
Long duration M2.6 eruption was responsible for a CME that is heading away from Earth. The source is AR 4419 which will return back into view this weekend. The flare itself was likely stronger than the M2.6 detected. SolarHam.com
Old sunspot region 4419, the source of two X-Flares on April 24th, is now getting set to turn back into view. solarham.com
The minor (G1) geomagnetic storm threshold was reached at 19:51 UTC (May 4) thanks to a prolonged period of southward Bz. SolarHam.com
Impressive CME produced by X2.5 flare on Friday morning is heading mostly away from Earth. Extreme edge of CME may pass close to Earth in days ahead, however no major impacts should be expected. solarham.com
