The Gannon superstorm may revisit Earth next week

LOS ANGELES. Space Environment Technologies (SET) has issued an updated Alert notice for possible geomagnetic storms starting as early as May 29, 2024 and extending to June 8, 2024 at the level of G1 or greater. This revised forecast notice places the timeframe of greatest possible storm activity between May 31 through June 6 2024. An Alert notice is the next notice level above Monitoring and is issued when an event threshold is crossed using information available at the time of issue. The information leading to this Alert notice includes the following events: 1) the confirmed return of the strong solar active region (AR) 3664 that created the Gannon superstorm on May 10-11, 2024 and 2) the continuing strong X-class flare activity from that region. NOAA SWPC reports that this region, which is just now at the East limb of the Sun, produced an X2.8 flare a 7 hours ago with peak time 07:08 UTC on May 27. The CME produced by that event is heading behind the Earth and the flux rope now making its way through the heliosphere in all likelihood will not affect the Earth. Our thanks to Clementina Sasso for the timely capture and post of the beautiful flare from GOES SUVI just beyond the East limb. Gannon Storm 2 Notice (2024/05/27 14:00Z)
