2月4日至5日,美国北部11个州发生强烈的太阳风暴,导致早期奥罗拉斯表面可见。 A powerful solar storm caused early auroras visible across 11 northern U.S. states on February 4–5.

2月1日强烈的X级太阳耀斑触发了日冕物质喷射,比预期提前到达地球,增加了2月4日至5日美国北部11个州可见的北极光的概率。 A strong X-class solar flare on February 1 triggered a coronal mass ejection that reached Earth earlier than expected, increasing the chance of visible northern lights across 11 northern U.S. states on February 4–5. 诺阿预测G1-G2地磁风暴条件,可能允许在华盛顿、爱达荷、蒙大拿、怀俄明、北达科塔、南达科塔、明尼苏达、威斯康星、密歇根、缅因和阿拉斯加看到极光。 NOAA predicts G1–G2 geomagnetic storm conditions, potentially allowing auroras to be seen in Washington, Idaho, Montana, Wyoming, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, Maine, and Alaska. 最佳观看时间为下午10时至上午2时之间,远离城市灯光的黑暗、清澈地点。 Best viewing is between 10 p.m. and 2 a.m. from dark, clear locations away from city lights. 2月4日的第二枚照明弹可能会将活动扩展至周末。 A second flare on February 4 may extend activity into the weekend. 由于条件迅速变化,建议采用实时预报和智能手机相机。 Real-time forecasts and smartphone cameras are recommended due to rapidly changing conditions.
