2024年英仙座流星雨即将如约而至，一场壮丽的宇宙盛宴即将在夜空展开。
每年的英仙座流星雨都是天文爱好者和广大观星者们期待的盛事，让我们一起来准备，迎接这场难的的自然奇观。The 2024 Perseid meteor shower is about to arrive as scheduled, and a magnificent cosmic feast will unfold in the night sky.
Every year, the Perseid meteor shower is an event that astronomy enthusiasts and stargazers look forward to. Let us prepare together to welcome this rare natural wonder.

英仙座流星雨是什么

What is the Perseid meteor shower?

英仙座流星雨(Perseids)与象限仪座流星雨、双子座流星雨并成为北半球三大流星雨，是一年中最具活跃度的流星雨之一，每年7月下旬到8月中旬达到高峰。这一现象是由地球穿越由彗星碎片留下的尘埃引起的，母体彗星为Swift-Tuttle彗星（109P/Swift-Tuttle），该彗星每133年会从地球附近擦过。

The Perseids are one of the three major meteor showers in the Northern Hemisphere, along with the Quadrantids and Geminids. They are one of the most active meteor showers of the year, reaching their peak from late July to mid-August. This shower is caused by the Earth passing through dust from comet fragments. The parent comet is Comet Swift-Tuttle (109P/Swift-Tuttle), which passes by the Earth every 133 years.

活跃期与极大期

Active Period and Peak

英仙座流星雨的活跃期很长，每年一般从7月17日到8月24日，持续一个多月，尤其会在8月12日至13日夜间达到极大期，在极大期期间，每小时天顶流量（ZHR）约为100。

The Perseid meteor shower has a long active period, generally lasting more than a month from July 17 to August 24 each year. It will peak especially on the night of August 12 to 13. During the peak period, the zenith flow rate (ZHR) per hour is about 100.

引用国际流星组织（IMO）数据，传统广泛极大期时间范围在λ⊙ ≈ 139.8至140.3之间，相当于2024年8月12日09时至21时协调世界时（北京时间12日17时至13日5时）。

According to data from the International Meteor Organization (IMO), the traditional widespread maximum time range is between λ⊙ ≈ 139.8 and 140.3, which is equivalent to 09:00 to 21:00 Coordinated Universal Time on August 12, 2024 (17:00 on the 12th to 05:00 on the 13th Beijing time).

观测准备工作

Observation preparation

2024年8月12日为上弦月，观测条件较为理想，虽然月光会影响部分观测，但高辐射点时间段基本不受干扰，对于北半球中纬度地区的观测者来说，最佳观测时间从本地时间22时至23时开始，辐射点将达到合理高度。

August 12, 2024, is the first quarter moon, and the observation conditions are relatively ideal. Although moonlight will affect some observations, the period of high radiant point is undisturbed. For observers in the mid-latitudes of the Northern Hemisphere, the best observation time is from 22:00 to 23:00 local time, and the radiant point will reach a reasonable height.

爱好者们应做好观测准备：

Observers should be prepared to:

前往远离城市光污染的地区，尽量白天到达观测地点，提前熟悉环境，确保安全以免夜晚出现意外。Go to an area away from urban light pollution, try to arrive at the observation site during the day, familiarize yourself with the environment in advance, and ensure safety to avoid accidents at night.
流星在天空任何一个角落都可能出现，需要寻找开阔无遮挡的地方观看。Meteors may appear in any corner of the sky, so you need to find an open, unobstructed place to watch them.
带好必备物品，预防蚊虫，防风衣物等，即使是夏季，凌晨的户外气温也可能降低，一些保暖衣物是必备之物。Bring necessary items, such as mosquito repellent, windproof clothing, etc. Even in summer, the outdoor temperature may drop in the early morning, so some warm clothing is a must.
提前确定观测地点的天气，观测流星雨需要晴朗的天气，出门前需要查询目的地晚上是否晴朗。Determine the weather at the observation location in advance. Clear weather is required to observe meteor showers. Before going out, you need to check whether the destination will be clear at night.

进入8月，英仙座在太阳落下不久就会出现在东北方的地平线了，英仙座流星雨的辐射点位于英仙座的北部，辐射点会在21时25分左右升起，这时我们会发现天空中流星的数量正在增多，尤其到了午夜时分，辐射点在天空较高位置时，观测到的流星数量也会进一步增加。

In August, the Perseids will appear on the northeast horizon shortly after the sun sets. The radiant point of the Perseid meteor shower is located in the northern part of Perseus. The radiant point will rise around 21:25. At this time, we will find that the number of meteors in the sky is increasing, especially at midnight, when the radiant point is in a higher position in the sky, the number of observed meteors will increase further.

在这个夜晚，让我们远离城市的喧嚣，投入到自然的怀抱中，与宇宙共舞，一同见证这场属于英仙座的璀璨星雨！

On this night, let us stay away from the hustle and bustle of the city, embrace nature, dance with the universe, and witness this brilliant star shower belonging to Perseus!
