BOOM! Old AR 3664 is back with a vengenance, popping off an X2.9 solar flare this morning. It obviously has survived its farside transit and is ready for more action! A CME seems to have occured with this flare but will not be Earth-directed. pic.twitter.com/IvNf9Ir6kS

The Sun emitted a strong solar flare on May 29, 2024, peaking at 10:37 a.m. ET. NASA’s Solar Dynamics Observatory captured an image of the event, which was classified as X1.4. pic.twitter.com/BAFB5Vby77

Region 3697 (old Region 3664) is at it again! A long-duration X1.45-flare and a nearly Earth-directed #solarstorm launch today. We may be grazed by the shockwave of this storm in a couple of days. Radio operators on the dayside are feeling this R3-level #Radioblackout for sure! pic.twitter.com/vNONHvktuZ

After producing fewer X-class flares around the back of Sun, old active region AR 13664 is finally back with a bang - producing an X3-class #SolarFlare this morning! All solar observatories are watching for whatever this region does next. #spaceweather #astronomy pic.twitter.com/j9xOhHkULs
