Overview
- NOAA's Space Weather Prediction Center issued a Kp index of 4 on Tuesday, a moderate geomagnetic level that can bring aurora into the northern U.S.
- The viewing line reaches as far south as Nebraska and Iowa, with the best odds in Alaska and states along the Canadian border.
- Best viewing is in dark skies between about 10 p.m. and 2 a.m. local time, away from city lights or glare.
- The forecast overlaps the peak of the Lyrids meteor shower, offering a chance to see meteors and the aurora in the same night.
- NOAA's aurora dashboard is back online after a brief outage, and forecasts point to a similar line but much lower odds on Wednesday.
