Live Kp signal
NOAA SWPC K-index tells you whether geomagnetic conditions are waking up.
Aurora forecast with cloud cover
Kp is not enough. Know if the sky will actually show it.
Aurora apps tell you when the Sun is active. DarkestHour adds the missing field layer: cloud risk, moonlight, darkness and local visibility so you know whether the chase is worth your time, setup or travel.
Cloud + moon filter
Aurora probability means little if the sky is blocked or a bright moon is washing out contrast.
Local chase decision
The paid layer should rank whether to wait, drive north/south, or save the fuel.
Confidence labels
Aurora forecasts are volatile. DarkestHour separates live data from estimated visibility.
Founding Pro push
Do not chase a Kp number into cloud.
Use Pro annual when the chase has fuel, time and sleep on the line: cloud, moon, darkness and local visibility in one decision before you commit.
