Tonight's Live Forecast
Massachusetts needs a Kp index of roughly 7+ for visible aurora. Below is tonight's answer, computed from the live Kp reading — updated hourly, explained calmly.

Unlikely in Massachusetts tonight
The Kp index is currently 4, below the roughly Kp 7 that Massachusetts needs for visible aurora. Watch for geomagnetic storm alerts — when Kp reaches 7+, tonight's answer changes.

What Massachusetts Needs for a Display
Massachusetts aurora sightings are strong-storm events: NOAA's Kp 7 view line passes near Boston, so a G3 storm is the realistic entry ticket, and the state's dense light pollution raises the practical bar further. When big storms do arrive, the dark hills of the Berkshires and the north-facing beaches of Cape Ann and Plum Island give the best geometry.
Boston sits near NOAA's Kp 7 (G3 storm) view line. Aurora visibility depends on geomagnetic latitude — which differs from map latitude by up to 15 degrees — so these thresholds come from NOAA SWPC's storm-level view-line estimates, not simple map position. Treat them as odds, not guarantees: at the threshold Kp, expect a glow low on the northern horizon rather than overhead curtains.

When to Look
10 PM – 2 AM local time, centered on midnight. September through March offers the darkest skies. Avoid full-moon nights and city light domes — even 30 minutes of driving makes a real difference.

Aurora visibility in Massachusetts is driven by the Kp index, so a Kp storm alert is effectively an aurora heads-up. The ResonanceOne app sends free push notifications when the Kp index reaches geomagnetic storm level (Kp 5+) — watch for readings of 7+ to match Massachusetts's threshold.
To be clear: ResonanceOne is not a dedicated aurora app — no aurora map, no location-based visibility forecast. It tracks the underlying signals (Kp index, solar flares, Schumann Resonance) in one calm Activity Index, and alerts you when they spike.
