英国将在8月迎来本世纪首次接近全日食现象,全国各地观众将看到月球遮挡太阳的90-96%[1]。这是自1999年以来的首次日食事件,也将是至2081年前的最后一次机会[1]。根据地理位置不同,各地的覆盖率存在明显差异。西部地区普利茅斯的覆盖率最高,达95%,而东部的设得兰群岛覆盖率最低,仅为88%[1]。其他主要城市的覆盖率分别为:卡迪夫93.2%、贝尔法斯特93.1%、曼彻斯特91.9%、伦敦91.4%、爱丁堡90.7%、纽卡斯尔90.2%[1]。
日食将从傍晚开始,其中爱丁堡和格拉斯哥的开始时间为下午6点08分,贝尔法斯特为6点10分,曼彻斯特和利物浦为6点13分,伯明翰为6点15分,伦敦为6点17分,康沃尔郡为6点18分[1]。日食在约一小时后达到最大,并在晚上8点左右结束[1]。与此同时,格陵兰、冰岛和西班牙北部将经历总日食,遮挡时间最长可达2分18秒[1]。
天文学家建议观众寻找高地位置进行观测,同时密切关注天气预报[1]。保护视力至关重要,必须使用符合国际安全标准ISO 12312-2:2015(E)的专业日食眼镜[1]。这一警告源于1999年全日食后,英国皇家眼科医学院报告的约70例视力问题病例[1]。
The United Kingdom will experience a near-total solar eclipse in August, with the moon obscuring 90 to 96 percent of the sun across the country [1]. This marks the first such event since 1999 and will be the last opportunity to witness this phenomenon until 2081 [1].
Coverage will vary significantly by location, with western regions enjoying the highest eclipse percentages [1]. Plymouth in the southwest will see 95 percent of the sun blocked, while Cardiff will observe 93.2 percent and Belfast 93.1 percent [1]. Coverage decreases toward the east and north, with Manchester experiencing 91.9 percent, London 91.4 percent, Edinburgh 90.7 percent, Newcastle 90.2 percent, and Shetland recording the lowest at 88 percent [1]. The eclipse will commence at 6:08 p.m. in Edinburgh and Glasgow, progressively starting later in other regions—6:10 p.m. in Belfast, 6:13 p.m. in Manchester and Liverpool, 6:15 p.m. in Birmingham, 6:17 p.m. in London, and 6:18 p.m. in Cornwall [1]. Maximum eclipse will occur approximately one hour after these start times, with the event concluding around 8 p.m. [1].
Astronomers recommend observers seek elevated locations for optimal viewing and monitor weather forecasts closely [1]. Critical to eye safety is the use of proper eclipse glasses that meet the international standard ISO 12312-2:2015(E) [1]. This precaution follows the 1999 total solar eclipse, when the Royal College of Ophthalmologists documented approximately 70 cases of vision problems [1]. Meanwhile, parts of Greenland, Iceland, and northern Spain will experience totality, with the moon completely covering the sun for up to two minutes and 18 seconds [1].
