FAQ
What is the Kp index?+
Kp is the planetary geomagnetic activity index. It is derived every 3 hours from 13 magnetic observatories and reflects global magnetic field disturbance.
How do I read the G1–G5 scale?+
G1 – minor storm (Kp 5), G2 – moderate (Kp 6), G3 – strong (Kp 7), G4 – severe (Kp 8), G5 – extreme (Kp 9). Below Kp 5 the magnetosphere is considered quiet.
Does Kp differ by city?+
No. Kp is a global index — the same for the whole Earth. Local impact depends on geomagnetic latitude: storms are more noticeable at higher latitudes.
Where do you get the data?+
Primary source: NOAA Space Weather Prediction Center (services.swpc.noaa.gov). Updated every 10 minutes.
More about the Kp index and magnetic storms
Right now the planetary Kp index is 0.7 — level quiet. Readings update every 10 minutes from NOAA Space Weather Prediction Center and are cross-checked with GFZ Potsdam.
Magnetic storms are disturbances of Earth's magnetosphere caused by the solar wind and coronal mass ejections. They are measured with the Kp index — a 3-hour global indicator compiled from 13 magnetic observatories worldwide. Kp ranges from 0 (quiet) to 9 (extreme).
Sections on this site: Today (hourly status and 72-hour forecast), Tomorrow (next-day forecast with expected max Kp), Chart (interactive 1 / 3 / 7 / 30-day Kp chart) and By city (local time, geomagnetic latitude and aurora chance for your city).
Right now the planetary Kp trend over the last 6 hours is easing — activity has fallen by about 1.7 points. The equatorial Dst index is 0 nT — the ring current is quiet and the magnetosphere is in a calm phase.
Alongside Kp this site tracks the Dst index (Disturbance Storm-time). Measured in nanoteslas, Dst reflects how strongly Earth's equatorial magnetic field is being pushed down by the ring current. Kp is a 3-hour global integral; Dst refreshes hourly and is the standard measure of a storm's main phase. A Dst above 0 nT means quiet conditions, −30 to −50 nT a weak disturbance, −50 to −100 a moderate storm, −100 to −200 an intense storm and below −200 an extreme event. Together the two indices give a fuller picture than either one alone.
