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.
Another R3 level solar flare erupts from active region 4366. The massive sunspot group remains magnetically complex and solar flares of at least the R1 level remain likely. There is no clear evidence yet of a CME with this most recent flare. Stay aware at https://t.co/TV7Yw6Lq1Y
LARGE CME OFF THE NW LIMB OF THE SUN: This is difference image (a picture with the previous frame subtracted). Here Light colours show brightening and dark dimming. This CME covers nearly half the Sun (a partial halo CME). Is it coming our way? Quite possibly - more detail later.
Babe, wake up, we have a new coronagraph.
NOAA shared the first images from the Compact Coronagraph (CCOR1), a powerful solar telescope onboard the new GOES-19 satellite today. CCOR is the world’s first operational, space-based coronagraph and began observing the sun’s corona on September 19, 2024.
Space weather forecasters around the world are rejoicing today with the new data stream that will allow for better, more timely measurements of coronal mass ejections.

Periods of G3 (Strong) geomagnetic storms are likely on 16 Sep 2024 due to coronal hole influences and the anticipated arrival of a CME associated with an X4.5 flare at 14/1529 UTC from AR3825.
CME WATCH - 2024.03.19: We have one nice bright CME off the southern polar region, otherwise there are a few minor faint CMEs. Only 1 posted on the 18th and 3 today.
A shock in the solar wind was observed around 08:47 UTC this morning. The shock is possibly related to partial halo coronal mass ejection launched February 28. Taking into account the current solar wind and IMF conditions, geomagnetic conditions are expected to rise to storm levels within the next couple of hours.
A large filament located in the NW quadrant lifted off beginning around UTC (Feb 21). A CME is now becoming visible. Based on trajectory, it should be well off the Sun-Earth line. More to follow if necessary.
