However, after further analysis, NOAA's Space Weather Prediction Center issued a Moderate (G2) geomagnetic storm watch for July 3, indicating that at least part of the CME could land Earth with a significant blow.

Largest #SolarFlare Of #SolarCycle25 Observed

May 14, 2024 @ 17:05 UTC (UPDATED)

"The largest solar flare of the current solar cycle 25, and largest since 2017 was just observed around deparing #AR3664 off the west limb. The #X8.7 event peaked at 16:51 UTC (May 14) causing a strong R3 level radio blackout directly over North America. More to follow.

"And Then...

"An eruption in the vicinity of newly assigned #AR3682 measuring M4.4 was observed at 17:38 UTC (May 14). This event looks to be eruptive, meaning a #CME will be produced.

"Solar Cycle 25 just kicked it up a notch!"
