NASA’s October 2026 forecast of the dimensionless 13-month-smoothed sunspot number, November 2026–October 2027. Dates mark monthly buckets, not exact-day predictions. Values use the sunspot 50th-percentile column, not the geomagnetic Ap columns; published 5th/95th percentile uncertainty is omitted from the line. Not a local aurora forecast.
