A minor (G1) geomagnetic storm watch is now in effect until 03:00 UTC (March 4). An enhanced solar wind stream containing sectors of southward Bz is currently moving past our planet.
Solar activity is now at moderate levels. A new active region turning into view from off the southeast limb produced an M2.4 solar flare at 15:59 UTC (Feb 25). Image by SDO/AIA.
A coronal mass ejection (CME) passed Earth at UTC (Feb 4). A geomagnetic sudden impulse measuring 16 nT was detected by a magnetometer in Boulder, Colorado. So far the impact appears to be fairly mild, however active (Kp4) to minor (G1) storm conditions may be possible today.
Longer duration X1.6 solar flare observed around AR 4366 peaking at 08:13 UTC (Feb 2). A further update will be provided later if a CME is associated. SolarHam.com
X-Class solar flare currently in progress around AR 4366. SolarHam.com
Impulsive X8.1 solar flare observed at 23:57 UTC (Feb 1). There was secondary peak of X1.5 at 00:22 UTC (Feb 2). More to follow. SolarHam.com
A strong X8.1 solar flare was just detected around AR 4366 peaking at 23:57 UTC (Feb 1). More to follow. solarham.com
At least fifteen M-Flares and one X-Flare produced by AR 4366 on Sunday (Feb 1st)... so far. No Earth directed CMEs appear associated at this time. SolarHam.com
Active sunspot region (AR 4366) is expanding quickly and producing frequent minor C-Flares. A moderate M-Flare will be possible on Saturday. SolarHam.com
Severe (G4) geomagnetic storm again in progress. Threshold reached at 08:23 UTC (Jan 20). SolarHam.com
Not something you see very often. Lower energy proton levels off the chart and a Severe (S4) radiation storm is currently in progress. solarham.com
Major X1.9 solar flare detected at 18:08 UTC (Jan 18) around AR 4341. Earth directed CME likely. More to follow. SolarHam.com
New spot growth observed within the southern section of AR 4341 on Wednesday and an M1.6 solar flare was detected at 20:32 UTC (Jan 14). SolarHam.com
A look at the CME leaving the Sun following a strong solar flare behind the southeast limb late on Sunday evening. It will be directed away from Earth. SolarHam.com
A strong solar flare was just observed beyond the southeast limb. Although peaking at M3.3, it was likely stronger because the source is now yet in view. A CME is now just becoming visible and will be directed away from Earth. We will begin to see the source later this week.
CME impacted Earth's geomagnetic field at 20:13 UTC (Jan 10). A minor (G1) geomagnetic storm is now in progress.
Incoming CME detected by ACE at 19:42 UTC (Jan 10). A minor (G1) to possible moderate (G2) geomagnetic storm watch is currently in effect for the next 24 hours.
Bz is currently pointing south. A minor (G1) geomagnetic storm watch is in effect. SolarHam.com
Moderate (G2) geomagnetic storm watch now in effect until 06:00 UTC (Jan 3). Bz south at times and solar wind speed around 600 km/s. SolarHam.com
M5.1 solar flare observed around AR 4323 at 01:50 UTC (Dec 27). This region is located within the remains of old regions 4294/4296 last seen earlier in December. solarham.com
X1.1 solar flare detected around AR 4298 peaking at 05:01 UTC (Dec 8). SolarHam.com
A faint halo CME associated with the M8 solar flare on Saturday is Earth directed with a predicted arrival time by December 9th. Moderate (G2) geomagnetic storming will be possible. More to follow in the days ahead. SolarHam.com
M8.1 solar flare detected this evening around AR 4299 (ex 4274). A faint, Earth directed CME appears to be associated. More to follow. SolarHam.com
AR 4300 getting into the action with this M6.0 solar flare detected at 02:50 UTC (Dec 4). SolarHam.com
The enhanced solar wind environment has prompted a strong (G3) geomagnetic storm warning which is now in effect until 23:59 UTC (Dec 3). Despite the full moon, aurora sky watchers at higher latitudes should be alert for aurora should local weather conditions allow.
AR 4274 is now turning back into view and just produced an X1.9 solar flare at 02:49 UTC (Dec 1). CME likely. SolarHam.com
A look at big sunspot region 4294 as it rotates into view on Saturday. The region is currently producing occasional M-Flares and is likely a threat for an isolated strong X-Flare. SolarHam.com
M5.9 solar flare observed around the soon to be reassigned AR 4294 at 22:22 UTC (Nov 28). SolarHam.com
A sizable eruption was just observed beyond the northeast limb beginning around 19:45 UTC (Nov 25). The associated CME will be directed away from Earth. Also note the large filament that is currently anchored in place in the NE quadrant.
A coronal mass ejection (CME) that includes a faint halo outline is emerging in updated imagery courtesy of GOES-19 CCOR-1. This appears to be related to farsided activity and is not Earth directed. SolarHam.com
