北极光现象在周五和周二晚间照亮了英国天空，可见范围涵盖从苏格兰北部至英国南部的广阔区域，包括德文郡、汉普郡和肯特郡等地 1。英国气象局表示，该现象由太阳活动和地磁风暴驱动，在天气晴朗的情况下可能持续至周二晚间 1。
这一自然景观由太阳风以约每小时100万英里的速度传播所引起 1。北极光呈现多种颜色，其中氧气产生绿色和稀有的红色极光，而氮气则产生蓝色和紫色的光晕 1。专家预计2026年将成为观测北极光的高峰年，届时太阳将处于其11年自然周期的活跃阶段 1。
The aurora borealis illuminated skies across the United Kingdom on Friday and Tuesday evenings, with visibility extending from northern Scotland down to southern regions including Devon, Hampshire, and Kent 1. The phenomenon was driven by solar activity and a geomagnetic storm, according to the UK Met Office, which indicated the lights could persist through Tuesday night in clear weather conditions 1.
The spectacular display results from solar wind traveling at approximately one million miles per hour 1. The varying colors of the aurora are produced by different atmospheric gases: oxygen generates the characteristic green hues and rare red lights, while nitrogen produces blue and purple glows 1. Looking ahead, experts anticipate that 2026 will mark a peak year for aurora observation, as the sun enters the most active phase of its 11-year natural cycle 1.
