During the total solar eclipse, what will the Sun's corona look like? Could a coronal mass ejection be departing the Sun? Maybe a massive solar prominence suspended above the solar disk? Only totality will tell! Visit swpc.noaa.gov/news/total-sol… for the full story of these images.

The CME on 28 March associated with the X1 flare (R3) was determined to not have any Earth-directed component.

Today's late afternoon X1 flare (R3) was associated with a CME as seen in this jhelioviewer.org video. The CME is being analyzed by SWPC forecasters for any Earth-directed component potential. Keep informed with the latest info and updates at swpc.noaa.gov

The G3 (Moderate) geomagnetic storm watch remains in effect. However, conditions are showing signs of weakening. G3 watch remains active until the end of the UT day, then lessening impacts expected to G1 (Minor) storm levels. Stay tuned to our website for updates and changes.

CME effects appear to be weakening. However, solar wind speed is still elevated and could result in further geomagnetic storming. The G2 (Moderate) warning has been extended until 1500 UTC on 25 Mar.

This is a video summary of the 22 March solar flares, coronal mass ejection (CME), and eventual CME arrival at Earth on 24 March - with resultant geomagnetic storms. The CME progression continues at this time.

The geomagnetic storm continues in response to CME passage. G1 (Minor) through G4 (Severe) levels were already reached with this storm. G3 (Strong) or higher storm levels remain possible into the evening as CME progression continues. Please visit swpc.noaa.gov for more.
