CHASING THE NORTHERN LIGHTS - A STEP BY STEP GUIDE FOR YOUR AURORA HUNT
提前计划
Maximise your chances of witnessing the Northern Lights by following our expert tips!
Two factors matter most when you plan your trip
-
The 27-day KP forecast: The 27-day KP forecast is based on the Sun’s rotation. Since the Sun turns once every 27 days, active regions can reappear and give a rough idea of aurora chances weeks ahead.
-
The moon phases: A bright full moon can wash out faint auroras, but it can also create magical photo opportunities by lighting up Iceland’s landscapes. Learn more about auroras and the moon phases here.
The Sun rotates roughly every 27 days, so active regions can reappear — giving a rough sense of aurora chances weeks ahead. Bars show forecast Kp; the line shows moon illumination, since a bright moon can wash out fainter displays.

足够黑暗的环境
清澈的天空
极光狩猎小贴士：如果您能看到星星，或许也能看到极光！
查看云层状况，寻找清澈的天空。使用时间滑块看看不同时间的云层变化，地图上的白色或浅色区域就是最佳观赏地点。
地图颜色说明：
🟢 绿色 – 所有云层（综合）
🔵 蓝色 – 低层云
🔴 红色 – 中层云
🟠 橙色 – 高层云（仍可能透过它们看到极光）

选择安全的地点
监测太阳活动
要看到极光，了解太阳活动非常重要，因为它直接影响极光的出现。极光指数（Kp index)从0到9，反映了地球磁场的扰动程度。如果极光指数在0到2之间，说明地磁活动较弱，看到极光的可能性不大。Kp为2到3时，极光的几率中等，可能会看到。Kp为4到6时，极光的机会很大，而且通常非常壮观。Kp在7到9之间则代表极强的活动，极光会更加明亮和广泛，虽然这种情况比较罕见。为了提高看到极光的机会，最好定期查看实时数据，了解最新的地磁活动信息。

UNDERSTANDING THE AURORA FORECAST
Auroral Activity (Kp Index)
The Kp index measures global geomagnetic activity on a scale from 0 to 9. The higher the number, the stronger the potential aurora.
Good for aurora hunting: Kp2 or higher usually means visible lights in most of Iceland.
Bz (North–South Magnetic Field)
The Bz component tells us the direction of the interplanetary magnetic field. When Bz is negative (–2 nT or lower), it opens a “door” in Earth’s magnetic field, allowing solar particles to enter and create auroras.
Ideal: –3 nT or below.
Bt (Total Magnetic Field Strength)
Bt shows the strength of the magnetic field carried by the solar wind. Stronger Bt (above 6 nT) increases auroral intensity when Bz is southward.
Ideal: Bt ≥ 6 nT combined with Bz ≤ –2 nT.
Solar Wind Speed
The solar wind is a stream of charged particles flowing from the Sun. Faster winds deliver more energy into Earth’s atmosphere.
Good chances: speeds above 400 km/s often produce bright, fast-moving auroras.
Combine all these indicators with clear skies and darkness for the best viewing conditions.
