Best times for the US

Season, hours, and sky conditions make the difference.

Season

Season controls how much darkness is available; geomagnetic activity and local weather can vary at any time.

Hours

Use local twilight and current conditions instead of a universal hour window.

Moon and clouds

Low clouds and a dim moon often matter more than a small Kp increase.

US regions and cities

Each region shows the typical Kp needed. Tap a city for the local forecast.

Frequently Asked Questions

What KP do I need?

Required KP depends on your magnetic latitude (MLAT). Higher MLAT needs lower KP. Check your local KP threshold on the city page, where we calculate it from MLAT.

When is the best time?

Use the 'best hour tonight' on each city page; it's based on KP, clouds and darkness window.

Can I see aurora in summer?

You need darkness. Twilight or bright moonlight cuts visibility considerably.

How accurate are aurora predictions?

AuroraMe presents geomagnetic activity, cloud cover, moonlight, darkness, and location-specific magnetic-latitude context. Use the latest source data and local conditions before viewing.

What's included in Aurora History?

Aurora conditions vary by solar activity, season, weather, and location. City pages provide planning context; they do not promise a number of visible nights.

How do quiet hours work?

Quiet hours prevent notifications during sleep (default 11 PM - 7 AM, customizable per location). Progressive urgency: strong aurora activity overrides quiet hours. Each location has independent settings with 30-minute cooldown between alerts.
