How long it gets fully dark in Des Moines
- The night after the 15th of each month: how long the sun stays more than 18° below the horizon. An aurora needs that dark sky – far north, summer has none at all.

How to see it
- Look toward the pole: North in the northern hemisphere, south in the southern – away from city lights.
- Use your phone's night mode: A camera shows colours the eye cannot see yet – the aurora often looks grey at first.
- Be patient: The aurora comes in bursts, often 20–30 minutes apart.
- Check the clouds: Without a clear view to the horizon nothing helps.
FAQ
- What does the Kp index mean? The Kp index measures from 0 to 9 how disturbed Earth's magnetic field is. The higher it is, the farther the auroral oval moves toward the equator. From Kp 5 NOAA speaks of a geomagnetic storm.
- When is the best time for the northern lights? Around magnetic midnight – in central Europe roughly between 10 pm and 2 am – and around the equinoxes in spring and autumn, when storms are a little more frequent.
- How reliable is the forecast? The Kp forecast for the next hours is quite good, for two or three days only rough: solar storms take one to three days to reach Earth, and their exact strength often only shows shortly before.
