Why this forecast?
Aurora Zone
Higher Aurora Zone = better aurora visibility. Your location's Aurora Zone determines how often auroras appear overhead.
Status Levels:
PerfectAbove 62.0° - Excellent aurora visibility (daily activity)
Good56.0° - 62.0° - Good aurora visibility (regular storms)
Acceptable50.0° - 56.0° - Fair aurora visibility (strong storms only)
LowBelow 50.0° - Poor aurora visibility (extreme storms)
Aurora Zone
Low 37.9°
Kp index
Kp measures global magnetic disturbance. Higher Kp = stronger auroras visible at lower latitudes.
Status Levels:
StormKp 6-9 - Geomagnetic storm, strong auroras
GoodKp 3-6 - Moderate activity, good conditions
LowKp 1-3 - Low activity, weak auroras
Very QuietKp 0-1 - Very quiet, minimal auroras
Kp index
Low 2
Cloud Cover Impact
Clear skies are essential for aurora viewing. Clouds block your view of the northern lights. The percentage shows cloud coverage (0-25% = clear, 85%+ = overcast).
Status Levels:
ClearClear (0-25%) - Perfect for aurora viewing
Partly CloudyPartly Cloudy (26-50%) - May partially block view
CloudyCloudy (51-85%) - Significantly blocks aurora
OvercastOvercast (85%+) - Blocks aurora completely
Cloud Cover Impact

Moonlight
Bright moonlight can wash out faint auroras. New moon provides the darkest skies for optimal viewing.

Aurora Borealis Viewing in Stara Zagora
Central city with very rare northern lights.
Stara Zagora sits at 37.9° magnetic latitude, which means aurora typically becomes visible when the Kp index reaches 9+. Aurora sightings in Stara Zagora require stronger geomagnetic storms (Kp 9+), which occur a few times per year. When storms do hit, the best viewing window is 10 PM to 2 AM local time under clear, dark skies.
Cloud cover is the most common reason people miss aurora even during strong storms. AuroraMe combines the Kp index with real-time cloud forecasts, moon phase, and darkness data to give you a single visibility status — so you know whether it's worth going outside tonight.
For the broader storm picture before checking Stara Zagora, start with the aurora borealis forecast and the geomagnetic storm tracker. Low-latitude places like Stara Zagora usually need a severe geomagnetic storm, clear northern horizon, and full darkness before northern lights become realistic.
