Frequently Asked Questions
What KP do I need?
Your required KP depends on magnetic latitude. Northern locations need lower KP values. Check your city page for the exact threshold calculated from your MLAT.
When is the best time?
Use the "best hour tonight" feature on each city page. It combines KP forecast, cloud cover, and darkness window to find optimal viewing time.
Can I see aurora in summer?
Aurora needs darkness to be visible. Summer's long daylight and bright moonlight significantly reduce aurora visibility, even during strong activity.
How accurate are aurora predictions?
AuroraMe combines 4 reality factors: NOAA OVATION space weather, cloud coverage, moon phase, and darkness windows. Location-specific KP thresholds are calibrated from 3+ years of historical data (8,768+ measurements).
What's included in Aurora History?
Multi-year statistical analysis with best months algorithm, calendar heatmap (12 months × 4 weeks), yesterday's observation windows, and location-calibrated frequency (Fairbanks ~50 nights/year vs Seattle ~5 nights/year).
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. 30-minute cooldown between alerts.
