X5.0 Flare Closes Out the 2023 Year

X5.0 Flare Closes Out the 2023 Year
published: Thursday, January 04, 2024 09:46 UTC

An X5.0 flare (R3 Strong Radio Blackout) from NOAA/SWPC Region 3536 occurred at 31/2155 UTC. This flare came from the same region that produced an X2.8 flare on December 14, 2023.  It is also the largest flare to be observed since September 10, 2017 when an X8.2 flare occurred. Although low confidence, modeling of the CME (Coronal Mass Ejection) related to this event determined the possibility of proximity shock influences near Earth as early as 02 Jan. A G1 (Minor) geomagnetic storming watch valid 02 Jan is in place in response. As always, stay tuned to forecast discussions found at https://www.swpc.noaa.gov/products/forecast-discussion for more details.
