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.

A moderate (G2) geomagnetic storm watch has officially been added for March 19th when a CME that left the Sun earlier today is expected to pass Earth. SolarHam.com

A coronal mass ejection (CME) is associated with an M2.7 solar flare early Monday around AR 4392. It is possibly Earth directed with an impact possible within 48-72 hours. A further update will be provided once SWPC release a proper forecast.

Moderate (G2) geomagnetic storm threshold reached at 23:40 UTC (March 13). Solar wind currently 600-700 km/s and Bz pointing south at times. SolarHam.com

An expected coronal hole stream is now reaching Earth. The minor (G1) geomagnetic storm threshold was reached at 11:59 UTC (Mar 13). High latitude aurora watchers should be alert during the next 24-48 hours. SolarHam.com

Coronal hole #31 is well established as it turns to face Earth. A high speed solar wind stream is expected to reach our planet beginning Friday (3/13). A minor (G1) geomagnetic storm watch has been issued.

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

Severe (G4) geomagnetic storm in progress following a strong CME impact. Visible aurora likely once dark outside. 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

A look at the halo CME associated with the X1.9 solar flare. Main bulk is heading to the east, however with the halo present, a passage past Earth is likely within 36 hours. SolarHam.com
