How we calculate the aurora score
LowWe combine geomagnetic activity (Kp), aurora oval probability (OVATION), cloud cover, darkness and moonlight, weighted for Rostock (region: mid_latitude).
With current Kp 5.0 (location needs ≥ 6) and 94% cloud cover, only a faint aurora is possible at Rostock, and only under otherwise perfect conditions.
Score 0–19. Conditions strongly limit aurora visibility.
Score 20–44. A faint aurora is possible only under perfect conditions.
Score 45–64. Aurora may be visible to alert observers in dark, clear skies.
Score 65–84. A good chance of a visible aurora display.
Score 85–100. Excellent odds — plan to be outside tonight.
Low chance tonight. Aurora may be possible only under very favorable local conditions.
Aurora visibility in Rostock is low tonight. A stronger geomagnetic storm or better local conditions would improve the chance of seeing the Northern Lights.
With current Kp 5.0 (location needs ≥ 6) and 94% cloud cover, only a faint aurora is possible at Rostock, and only under otherwise perfect conditions.

Best Viewing Window
1:00 AM – 3:00 AM
This is the best available window, but geomagnetic activity is expected to be low.
Direction to Look
North
At this latitude, aurora is usually seen toward the northern horizon.
Recommendation
Check the forecast again later. Aurora conditions can change quickly during geomagnetic activity.

Why this forecast?
There is a low chance of visible aurora tonight. Some conditions may help, but overall the forecast does not strongly support visibility.
Score breakdown
How tonight's aurora score for Rostock breaks down into activity and visibility components.
?
Geomagnetic activity
7 / 40Geomagnetic activity (Kp 5.0) contribution to the score.
?
Aurora oval probability
0 / 20OVATION aurora oval probability (0%) contribution.
?
Cloud cover
1 / 20Cloud cover (94%) contribution — clear skies score full points.

Darkness
15 / 15Sky darkness contribution — astronomical darkness scores full points.
?
Moonlight
1 / 5Moon illumination (77%) contribution — new moon scores full points.

Geomagnetic activity (Kp index)
Near thresholdKp measures how disturbed Earth's magnetic field is on a 0–9 scale. Higher Kp pushes the aurora oval toward the equator. Rostock needs Kp ≥ 6.
Kp is below the minimum needed at this latitude.
Kp is close to the minimum needed — a faint aurora may appear low on the horizon.
Kp meets the threshold for visible aurora here.
Kp is comfortably above the local threshold.
Storm-level Kp ≥ 5 — aurora can be seen far south of its usual zone.
Near threshold
Geomagnetic activity is close to the threshold for Rostock: expected Kp is 5.0, and this location usually needs around 6. A faint aurora low on the horizon is possible.
?
Cloud cover
OvercastAverage cloud cover during the best viewing window. Clear skies are essential — even thin overcast hides the aurora.
Up to 25% cloud — excellent visibility.
25–50% cloud — aurora may peek through gaps.
50–85% cloud — most of the sky is blocked.
Over 85% cloud — aurora effectively hidden.
Overcast
Cloud cover is high tonight, which can block the view even if aurora activity is present.
?
Sky darkness
Astronomical darknessAurora is faint and needs a dark sky. Astronomical darkness (sun more than 18° below horizon) is ideal.
Sun stays above 6° below horizon all night — no aurora-friendly darkness.
Sun 6–12° below horizon — too bright for faint aurora.
Sun 12–18° below horizon — sky is dark but not fully astronomical.
Sun more than 18° below the horizon — fully dark sky.
Astronomical darkness
The sky reaches full astronomical darkness tonight — the sun more than 18° below the horizon, dark enough for even a faint aurora.
?
Moon illumination
Bright moonA bright moon washes out faint aurora colours. New moon is ideal; full moon hides everything but the strongest displays.
Less than 25% illuminated — minimal interference.
25–75% illuminated — faint aurora may be washed out.
Over 75% illuminated — only strong displays will be visible.
Bright moon
Moon is 77% illuminated — expect washed-out faint aurora.
?
Aurora oval probability (OVATION)
LowNOAA's OVATION model estimates the chance of aurora visible overhead within a 250 km radius of you.
Less than 5% probability — aurora unlikely to reach this location.
5–20% probability — aurora possible.
20–40% probability — aurora likely if skies are clear.
Over 40% probability — aurora very likely overhead.
Low
The aurora oval probability is low for this location tonight.
?
Aurora zone
Fair zoneHow favourable Rostock's latitude is for aurora viewing in general — independent of tonight's conditions.
Lower latitude — aurora is rare and requires a major storm.
Mid-latitude — aurora visible only during moderate-to-strong storms.
High-latitude region — aurora is visible on most active nights.
Directly under the auroral oval — aurora is a regular occurrence.
Fair zone
Rostock is in an occasional aurora region, so stronger geomagnetic activity is usually needed.

Frequently Asked Questions
Can you see the Northern Lights in Rostock tonight?
Only during a storm. Rostock needs Kp 6 or higher before the oval reaches it, and that happens a handful of nights in a year rather than most weeks. Even then it takes a clear sky, real darkness and a dim moon — cloud blocks aurora at any Kp.
What Kp index is needed to see the Northern Lights in Rostock?
Rostock lies at 50.6° geomagnetic latitude — roughly 15° south of the quiet oval's edge — so it takes a geomagnetic storm, Kp 6 or higher, before the ring reaches you, low on the northern horizon rather than overhead.
What are the best months to see the Northern Lights in Rostock?
September to April, with November to February the darkest stretch — though at this latitude the season is set by how often a storm reaches you, not by daylight.
Where is the best place to see the Northern Lights in Rostock?
Rostock is large enough that its own sky-glow is the main obstacle, so plan on leaving it. Head out away from the lit side until the glow is behind you, and find an open view toward the north — a lake shore, a ridge, anywhere the horizon is not built up. Let your eyes adjust for 20–30 minutes once you are there, and keep the phone screen off.
