The geomagnetic field over Cherry Hill is quiet. The planetary Kp index is 0.3 — about 0.3 as effective local exposure at this latitude — and the next 72 hours should stay comfortable, peaking near Kp 2.7 around Sat 02:00 AM local time.
Cherry Hill sits at geomagnetic latitude 49° — and that latitude, not the city itself, decides how strongly a storm is felt: we estimate local exposure at ×1.01 of the planetary Kp. Auroras become plausible here from about Kp 7. All times on this page are shown in Cherry Hill local time (UTC-4).

Official 3-hour NOAA windows relabelled to Cherry Hill's clock (UTC-4). The curve is planetary — the local feel scales with latitude.
Forecast peak Kp 2.7 around Jul 18, 02 AM.
When to get things done and when to rest. The marker shows now (20:00).
Official NOAA Kp forecast with a general wellbeing-risk estimate for weather-sensitive people.
Two local estimates: aurora visibility and general wellbeing impact.
Auroras become plausible over Cherry Hill from about Kp 7 — the auroral oval has to expand down to geomagnetic latitude 49°.
Best night this week: Friday (≈2% by the daily forecast).
Best around local midnight — look north, away from city lights. Chances are an estimate from the planetary Kp peak and latitude.
A comfortable window. Good time for demanding tasks, workouts and travel plans.
General population-level guidance, not medical advice. Reactions are individual — a symptom diary shows what actually affects you.
Same storm, slightly different latitude — open a neighbouring page for its local timing and aurora odds.
No — the field is quiet. Kp is 0.3 right now, and the next 72 hours peak near Kp 2.7 around Sat 02:00 AM local time. Kp 5 or higher would count as a storm.
Sometimes. Cherry Hill is at geomagnetic latitude 49°, so auroras become plausible from about Kp 7. Tonight's estimated chance is 2% — best around local midnight, away from city lights.
The Kp index itself is planetary — one number for the whole Earth. What changes is how strongly a place feels it: at Cherry Hill's geomagnetic latitude (49°) we estimate the effective exposure at about ×1.01 of the planetary value.
Research is mixed, but many weather-sensitive people report headaches, fatigue or restless sleep during elevated activity. It is a possible correlation, not a diagnosis — the forecast above shows when the sensitive windows are, and a symptom journal shows whether they matter for you.
