Overview
- Forecasters expect geomagnetic activity near Kp 5 on Tuesday night, which can push aurora to lower latitudes than usual.
- NOAA’s viewline shows potential visibility from Alaska through the northern tier, including northern Iowa and South Dakota.
- Activity is likely to build after dark and continue into early Wednesday, consistent with short, variable bursts from coronal‑hole streams.
- The outlook is G1 (Minor) on NOAA’s scale, indicating limited operational impact with only occasional brief HF or GPS disturbances possible.
- Best viewing practices include checking NOAA’s 30‑minute aurora forecast or aurora apps, seeking dark northern horizons, and monitoring real‑time Bz and cloud cover.
