he best time to see the Aurora Borealis is during the winter when the nights are longer and darker. This article provides information on when Aurora can be seen best. The best viewing months for the northern lights are September through April. During this period, it is the darkest time of night thus increasing visibility chances. Technically active all year round, but hardly visible in summer due to incessant daylight in northern regions (“midnight sun”).
The optimal timing for observing auroras is at night between 10 PM and 2 AM. Anytime of other nights also can be used if there are dark skies above your head. Avoid light pollution; look for remote areas away from city lights where you live or travel to enjoy this phenomena better; one needs clear or mostly clear skies as clouds will obstruct viewing of Northern Lights.
Track the solar activity and geomagnetic storm forecasts (KP index). The more KP index is, the higher are the chances to see Aurora. Solar activity forecasts can be tracked in several significant ways. For example, NOAA Space Weather Prediction Center provides three-day forecast of geomagnetic activities and visibility of Aurora borealis. Real-time updates are provided via apps like "My Aurora Forecast" or "Aurora Alerts". SpaceWeatherLive reveals detailed information about current solar and geomagnetic activities. Additional sources include Norwegian Centre for Space Weather as well as Swedish Institute of Space Physics that provide localized forecasts.
Phases of the Moon
New moon’s time is preferable because it will make sky darker without added light from moonlight that makes easier recognition of an aurora possible. A full moon may hide an aurora if you would happen to plan your observation during full moon phase.
Nevertheless, through careful planning combined with accurate monitoring of Aurora forecasts from reliable sources, you can greatly increase your probability of observing this wonderous natural phenomenon. This kind of preparedness increases your chances not only to locate the Northern Lights but also experience them more powerfully than ever before.
