Overview
- NOAA forecasts a G1 geomagnetic storm late Friday into early Saturday with a modeled Kp peak near 4.67, then a decrease toward Kp 4 overnight into Sunday.
- Forecast maps place roughly ten states near the aurora view line, with Idaho, Montana, North Dakota, Minnesota, Wisconsin and Michigan favored Friday and Washington, South Dakota and Maine highlighted Saturday.
- An updated outlook for Saturday night notes the potential for brief G2 periods and auroras on the northern horizon in up to about 15 states if incoming CMEs align more directly with Earth’s field.
- Best viewing typically falls between 10 p.m. and 2 a.m. from dark, high, north‑facing locations, and real‑time NOAA tools are recommended for short‑notice changes.
- For photography, use Night mode on iPhone or Pro mode on Android, disable flash, shoot RAW when possible, set camera aperture to f/4 or lower, and stabilize the device with a tripod.
