Overview
- NOAA’s latest watch calls for geomagnetic storming Nov. 11–12 with Kp values up to about 7.33, signaling the potential for widespread aurora visibility beyond typical northern latitudes.
- The UK Met Office has issued a G3 “strong” alert and reported recent R3 radio blackouts from X‑class flares, with the best UK viewing prospects in northern regions under clear skies.
- Two Earth‑directed coronal mass ejections are arriving and could interact, with Spaceweather.com noting a possible rare “cannibal CME,” an outcome that would be assessed in real time.
- In the U.S., displays could reach as many as 22 states from the northern tier into parts of the Upper Midwest and possibly Oregon, with prime viewing generally from about 10 p.m. to 2 a.m. local time and a UTC peak window around 0300–0900.
- Forecasters caution that cloud cover, moonlight and the interplanetary magnetic field orientation will determine actual visibility and impacts, with elevated activity likely into Wednesday before easing later in the week.
