Latest Space Weather News Minor (S1) Radiation Storm January 3, 2024 @ 20:10 UTC Low energy proton levels streaming past Earth continue to gradually rise and is now finally at the minor (S1) radiation storm threshold. This is a direct result of the X5 solar flare now almost 72 hours ago. Needless to say, had AR 3536 been directly facing Earth when the flare was observed, a proton event and strong geomagnetic storm would have been very likely. Only minor HF signal degradation through the polar zones should be expected because of the minor (S1) storm. CME Mostly A Miss / Storm Watch Cancelled January 2, 2024 @ 20:05 UTC (Updated) As of this update, the CME that left the Sun late on December 31st generated by an X5 solar flare has yet to be clearly detected. This means the western flank of the CME shock is likely traveling slower than predicted. Low energy proton levels remain elevated, so it is possible it could still pass our planet at some point during the next 12 hours. It is also possible that the impact would be weak, or it will pass too far behind Earth to notice. A minor (G1) geomagnetic storm watch remains in effect for now. CME Mostly A Miss: According to the latest NOAA/SWPC update, the X5/CME was mostly a miss. Geomagnetic storming is no longer in the forecast. A further update will be provided should conditions change. X5 CME Event Update January 1, 2024 @ 18:40 UTC (Updated) An official tracking model courtesy of NOAA/SWPC is now available for the X5.0 flare event. They are in fact calling for the extreme western edge of the associated CME to pass Earth by January 2nd. Geomagnetic storming will be possible should an impact be observed as predicted. Stay tuned for updates during the next 24 hours.
