LIVE AURORA FORECAST
OCTOBER 18TH
Aurora activity is expected to be moderate to high tonight, with the Kp index peaking around 4 — offering favorable conditions for visible displays, if the skies stay clear.
Cloud cover is looking promising overall. More cloudiness is expected in eastern and northern Iceland later in the evening, but Reykjavík and surrounding areas are forecast to enjoy clearer skies during prime aurora hours.
Best window to watch: 22:30 to 00:30 (local time). When the sky is darkest, with a bit of luck, the northern lights may come alive.
TONIGHT’S OUTLOOK
CHASING THE NORTHERN LIGHTS - A STEP BY STEP GUIDE FOR YOUR AURORA HUNT
Plan your Northern Lights hunt with Iceland’s most complete aurora forecast. A clear 6-step guide combining KP index, solar activity, cloud cover, and the best locations to watch the aurora.
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.
足够黑暗的环境
秋季、冬季和春季是观赏极光的最佳时机，因为看到极光需要黑暗的环境。而在冰岛的夏季，几乎全天24小时的阳光使得观赏极光变得不可能。为了帮助您找到最佳观赏地点，下面我们提供了一张地图，标出了冰岛主要的光污染区域。远离这些标色区域，您将能更清晰地看到北极夜空。此外，我们还制作了一份 详细的指南，帮助您避开光污染，最大限度地提高目睹这一壮丽景象的机会。
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
在冰岛追逐极光意味着您将走在黑暗的路上，常常是在结冰或积雪的道路上，因此安全是最重要的。不要在路边停车，这样不仅危险，还可能影响到其他司机的安全。最好选择指定的停车区，这样更安全。为了让您轻松享受这段冒险，参加我们的旅行团吧！由北极光专家为您安排好所有的计划和安全问题，让您可以尽情享受极光的美丽。
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.

常见问题
为什么极光预报会有变化？
极光预报会不断变化是因为太阳总是充满着惊喜！太阳活动（如太阳耀斑和太阳风）时刻都在变化，直接影响极光出现的方式和地点。地球上的天气条件，尤其是云层覆盖，也会对观测产生很大影响。这就是为什么查看实时更新能让你抢占先机，享受最佳极光体验的原因。
还有其他极光数据来源我应该关注的吗？
是的！您可以关注雷尔沃古尔磁气观测站，它追踪冰岛的磁场扰动。当图表显示磁场活动增强时，意味着太阳风正在扰动地球的磁场——这通常会导致极光爆发。将其与Kp指数和实时预报一同监控，可以为你提供最佳的观赏极光的机会！
极光指数有多准确？
极光指数（Kp Index）是衡量地磁活动和预测极光的可靠工具，但并不完美。它提供的是基于3小时周期的总体预报，因此条件可能会迅速变化。为了获得最准确的预报，可以将Kp指数与太阳活动、云层覆盖情况以及当地磁场扰动的实时数据结合使用。
在冰岛观赏极光的最佳月份是什么时候？
在冰岛观赏极光的最佳月份是从九月到四月。在此期间，夜晚最长最黑，创造了理想的极光观赏条件。最适合的月份是十月到三月，这时天空最黑，太阳活动通常也较强。只要记得查看天气预报，确保天空晴朗清澈。
极光指数的高低在观赏极光方面有什么区别？
低极光指数（Kp 0-2）意味着极光可能会很微弱，呈现为柔和的淡光——通常看起来像薄云——通常只在遥远的北部地区可见。高极光指数（Kp 5-9）则带来生动、动态的极光展示，明亮的绿色、紫色甚至红色在天空中舞动，有时甚至在较南的地区也能看到。
夏天能看到极光吗？
在冰岛的夏天看到极光几乎是不可能的。从五月到八月，冰岛因极昼现象几乎全天都有阳光，使得天空太亮，无法看到极光。为了有最佳机会观赏极光，建议在九月到四月之间前往，这时夜晚黑暗且漫长。
有哪些推荐的极光预报应用程式APP？
