Northern lights may be visible in 10 states tonight

北极光今晚或在美国 10 个州可见

The northern lights could still be visible tonight (Nov. 13-14) as lingering effects from recent solar eruptions continue to ripple through Earth's magnetic field.

11 月 13 日至 14 日夜间，北极光仍可能现身 —— 由于近期太阳爆发产生的余波，正持续在地球磁场中扩散。

Minor (G1) to strong (G3) geomagnetic storm conditions are still possible throughout the evening hours, according to NOAA's Space Weather Prediction Center. A G3 storm watch remains in effect today with a gradual return to quieter space weather expected by Friday, according to the U.K. Met Office

根据美国国家海洋和大气管理局（NOAA）空间天气预报中心消息，整个夜间仍有可能出现小（G1 级）至强（G3 级）地磁风暴。英国气象局表示，G3 级地磁风暴警戒今日持续生效，预计到周五空间天气将逐步恢复平静。

While geomagnetic activity is slowly subsiding, the current forecast still shows a good chance of auroras in parts of the northern U.S.

尽管地磁活动正缓慢减弱，但当前预报显示，美国北部部分地区仍有较高概率出现极光。

Based on the latest NOAA aurora forecast map, the following 10 U.S. states appear fully or partially above the aurora view line:

根据美国国家海洋和大气管理局（NOAA）最新极光预报图，以下 10 个美国州完全或部分处于极光可见线之上：

Alaska

阿拉斯加州

Washington

华盛顿州

Idaho

爱达荷州

Montana

蒙大拿州

North Dakota

北达科他州

South Dakota

南达科他州

Minnesota

明尼苏达州

Wisconsin

威斯康星州

Michigan

密歇根州

Maine

缅因州

As always, keep in mind that auroras are not guaranteed. Sometimes they appear farther south than forecast and sometimes not at all. Many conditions have to align for a good display, including cloud cover, light pollution and the strength of the geomagnetic disturbance.

一如既往，需谨记极光并非绝对能观测到。有时它们会比预报范围更偏南出现，有时则完全不现身。极光的壮观呈现需多种条件同时满足，包括云层覆盖、光污染情况以及地磁扰动的强度等。

The northern lights could be visible across 10 U.S. states (or maybe more) tonight (Nov. 13-14) as soon as it gets dark, so it's worth keeping an eye on the sky throughout the evening, especially in areas with clear, dark skies.

北极光可能在全美 10 个州（甚至更多）现身，11 月 13 日至 14 日夜间天一黑就有可能观测到，因此整晚都值得留意天空，尤其在天空晴朗、无灯光干扰的区域。

According to NOAA's 3-day forecast, geomagnetic storm activity is expected to be highest earlier on in the night, with the best chances of auroras during the following key times:

根据 NOAA 太空天气预报中心 (SWPC) 最新 3 天预报，今晚 (11 月 13-14 日) 地磁风暴活动预计在以下关键时段达到高峰，是观测北极光的最佳时机：

4 p.m. - 7 p.m. EST (2100-0000 GMT): Strong G3 storm levels possible

美国东部时间下午 4 点至 7 点（EST，对应格林威治标准时间 21:00 至 00:00）：可能出现强 G3 级地磁风暴。

7 p.m. - 10 p.m. EST (0000-0300 GMT): Minor G1 storm levels possible

美国东部时间晚上 7 点至 10 点（EST，对应格林威治标准时间 00:00 至 03:00）：可能出现小 G1 级地磁风暴。

If you live in one of the 10 U.S. states forecasted to catch a glimpse of the northern lights tonight, there are a few things you can do to give yourself the best chance of seeing them.

如果您居住在预报今晚有望观测到北极光的 10 个美国州之一，以下几点建议能帮您最大程度提高观测成功率。

Find a north-facing vantage point with a clear view of the horizon as far from light pollution as possible.

寻找一处朝北的有利观测点，需视野开阔、能清晰看到地平线，且尽可能远离光污染。

Use your phone camera to scan the sky, as the camera is great at picking up faint auroras before your eyes spot them. This will give you a good idea of the direction you should be focusing your attention.

用手机相机扫视天空即可，因为相机很擅长捕捉微弱极光，能比肉眼先发现它们。这能帮你明确该重点关注的方向。

Try to let your eyes adapt to the dark for at least 30 minutes; this will help your night vision develop.

尽量让眼睛适应黑暗，时长至少 30 分钟；这能帮助提升你的夜视能力。

Wear warm clothing! Part of the fun of aurora hunting is the chase. Be prepared to sit or stand for hours if conditions are looking promising, as you won't want to miss the show when it starts!

注意保暖！追逐极光的乐趣之一就在于这份寻觅的过程。如果观测条件向好，要做好久坐或久站数小时的准备 —— 因为你一定不想错过极光盛宴登场的瞬间！

We recommend downloading a space weather app that provides aurora forecasts based on your location. One option I use is "My Aurora Forecast & Alerts," available for both iOS and Android. However, any similar app should work well. I also use the "Space Weather Live" app, which is available on iOS and Android, to get a deeper understanding of whether the current space weather conditions are favorable for aurora sightings. Our guide on how to photograph auroras is designed to help you capture the moment with a breathtaking photo.

我们建议下载一个太空天气应用程序，它可以根据你的位置提供极光预报。我使用的一个选项是“我的极光预测和警报”，适用于iOS和Android。但是，任何类似的应用程序都应该运行良好。我还使用iOS和Android上都有的“太空天气直播”应用程序，以更深入地了解当前的太空天气条件是否有利于极光观测。我们关于如何拍摄极光的指南旨在帮助你用令人惊叹的照片捕捉瞬间。
