原文:
Follow a sunset on a clear day against a distant horizon and you might glimpse a green flash just as the Sun disappears, the sunlight briefly refracted over a long sight-line through atmospheric layers. You can spot a green flash at sunrise too. Pinpointing the exact place and time to see the rising Sun peeking above the horizon is a little more difficult though, and it can be harder still to catch a green flash from the fainter rising Moon. But well-planned snapshots did record a green flash at the Full Moon’s upper edge on June 2nd, from the Roque de los Muchachos Observatory on the Canary Island of La Palma. Looking a little south of due east, this long telephoto view finds the rising Moon above mountains and a sea of clouds. In sunlit profile are the mountaintop Teide Observatory telescope domes on the island of Tenerife some 143 kilometers away.

在一個晴朗的日子,當你追隨夕陽沿著遙遠的地平線,或許能在太陽消失的瞬間瞧見一抹綠閃。這股光晕是陽光在穿越大氣層的長距離視線中稍微折射而成的現象。雖然在日出時也能捕捉到綠閃,但精確地定位日出時太陽在地平線上微微露出的時刻則稍顯困難,而從微弱的上升月亮中捕捉綠閃則更加不易。然而,計劃周詳的拍攝確實記錄下了2023年6月2日的滿月時分,綠閃在月亮的上邊緣出現。這幅長焦距的觀景圖是從位於加那利群島拉帕爾瑪的羅克德羅斯穆查丘斯天文台拍攝的。望向南偏東的方向,這顯現出上升的月亮高掛於山脈之上,並懸浮在雲海之上。在陽光照射下,加那利群島另一座143公里遠的特內里費島上的特內里費天文台望遠鏡圓頂的山頂也清晰可見。
