Pentax k3II+FA31/1.8 固定攝影曝光十秒, 部分裁切
今年的英仙座流星雨沒有受到月光的影響,雖然偶而有雲經過干擾,
數量與預期差不多,8/13的晚上11:00至14日凌晨4:00在鞍部共約觀賞到約流星40顆(沒有仔細算),算是英仙座流星雨(在 bortle5 夜空)的正常發揮。
如果團體要增進彼此的感情,相約去看英仙座流星雨是個妙方,失敗的機率很低。
根據IMO國際流星組織後來的統計(IMO Perseids Live ZHR),極大期的峰值天頂小時率平均 ZHR約70(換算成陽明山鞍部每小時約12顆),又若根據IMO Video的實時統計 (IMO Video Meteor Network, MeteorFlux 2.1 Realtime Viewer) 這次的極大期持續的時間很長,約從13日的中午至14日凌晨,其中極短的時間ZHR曾到110左右。
很意外的是,8/13晚上仰德大道上竟然沒什麼車流,或許是星期天的關係?沒上來很可惜啊郊山就是要看三大流星雨。鞍部沒有很多人(擎天崗應該不少人。)
This year's Perseid meteor shower was not affected by moonlight, despite occasional disruptions caused by passing clouds. The observed quantity of meteors was nearly in line with expectations. From 11:00 PM (Local time) on August 13th to the early hours of the 14th, a total of around 40 meteors were seen at the Anbu area, Yangmingshan. This can be considered a typical manifestation of the Perseid meteor shower in the bortle 5 night sky.
If a group intends to enhance their mutual feelings, arranging to watch the Perseid meteor shower together is an ingenious approach, with a very low probability of disappointment.
According to later statistics from the International Meteor Organization (IMO), the average Zenithal Hourly Rate (ZHR) during the peak period was about 70 (equivalent to approximately 12 meteors per hour at Yangmingshan's Anbu area). Based on IMO's Video real-time data, the peak period of this event lasted a considerable duration, spanning from noon on the 13th to the early hours of the 14th, with a brief period during which the ZHR reached around 110 (Local time).
Surprisingly, on the night of August 13th, there was scarce vehicular traffic on Yongde Boulevard. This might be attributed to it being a Sunday. It's quite a pity that not many people came up; after all, observing the three major meteor showers is a key attraction of suburban life. The Anbu area also had a modest turnout (Qingtianagng probably had a larger crowd).
