Medium sensitivity (mid latitudes)
Kp is a planetary index — the same globally. Local impact depends on geomagnetic latitude: the higher it is, the more noticeable the storm.

* Days marked with an asterisk do not have a direct NOAA forecast yet. If we have observations from 27 days ago, we use Bartels recurrence (the Sun rotates roughly every 27 days, so active regions often return with the same period). When no history is available, we substitute a baseline value typical for the current solar cycle 25 peak (Kp 3.0). Accuracy is lower than the direct three-day forecast.
How the score works
The composite score combines three signals: how strong the storm needs to be at your geomagnetic latitude, how bright the moon will be (a full moon hides faint auroras), and how cloudy the sky will be that night. A score of 70 or higher is excellent, 45 to 70 is good, below 20 means you probably will not see anything.
Magnetic storms in Lexington over the last 30 days

About magnetic storms in Lexington
Magnetic storm in Lexington today: planetary Kp = 0.0 (quiet). Over the last 7 days the maximum Kp above Lexington reached 5.3 (G1); storm days (G1+) this week: 2.
Lexington sits at geomagnetic latitude 47.1°. The nearest magnetic observatory continuously recording the field is Lovozero (Murmansk), 7213 km away. Population 320,347.
Lexington is located at mid-latitudes (47.1°), where storm effects on the body are usually mild and noticeable mainly during severe G4 to G5 events. At Kp ≥ 6, some weather-sensitive people may report pressure swings, headaches or restless sleep; routine precautions like extra hydration, less caffeine and lighter physical load during the strongest events are usually enough.
For most technical systems in Lexington (47.1°, mid-latitudes), routine geomagnetic activity has little practical effect. Noticeable GPS, HF radio or grid issues are largely confined to severe G4 to G5 storms. Long-haul drivers, surveyors and HF operators in the region may want to check the forecast during the strongest events. Source: NOAA Space Weather Prediction Center, refreshed every 10 minutes.
Over Lexington during the last 24 hours. Kp reached a maximum of 2.3 around 20:00 local time and dipped to 0.7. The planetary trend over the past 6 hours is falling — the magnetosphere near Lexington is in the recovery phase. So far this month the planet has logged 2 days with a G1 or stronger geomagnetic storm.
Aurora visibility threshold for Lexington. At a geomagnetic latitude of 47.1°, the minimum Kp giving a realistic chance of visible auroras above Lexington is about Kp ≥ 7. The current equatorial Dst index is 0 nT — the magnetosphere is in a quiet phase. Dst complements Kp by showing how long and how deep a storm's main phase has been — useful context when checking whether auroras are likely tonight.
Weather and atmospheric pressure in Lexington right now. Temperature +14.3°C, atmospheric pressure 736.6 mm Hg (982.1 hPa), cloud cover 0%, humidity 77%, wind 6.4 km/h. During G1+ geomagnetic storms, swings in atmospheric pressure tend to amplify symptoms for weather-sensitive people: those with hypertension often notice blood-pressure spikes, and readings below 1000 hPa combined with Kp ≥ 5 frequently bring headaches and fatigue. That is why the Lexington page shows both indicators side by side. Weather data from Open-Meteo (CC BY).
Aurora viewing window for Lexington tonight. Sunset is at 13:19 local time, sunrise tomorrow at 00:01. Moon phase — waxing gibbous with 86% disk illumination. The Moon is close to full tonight, so moonlight will be strong and faint auroras will be harder to spot — wait for Kp ≥ 6 or pick a darker site..
