Overview

• NOAA’s latest outlook calls for Kp index readings around 3–4 on August 12–13, with a chance for G1 (minor) geomagnetic storms driven by a positive-polarity coronal hole high-speed stream.
• Aurora viewline maps show roughly ten northern states—from Alaska through Maine—within the potential visibility zone after dark.
• Observers should seek dark, north-facing skies between about 10 p.m. and 2 a.m. local time and monitor NOAA’s 30-minute forecasts for real-time updates.
• Some nights in NOAA’s three-day forecast window are expected to be calmer, with no significant solar wind features and a maximum Kp of around 2.
• Short summer nights reduce dark-sky hours, so clear conditions and low light pollution remain essential for catching any auroral displays.
