Taken on March 20 from the top of Haleakala on the isle of Maui, planet Earth, the first sunrise of northern spring is pictured in this vacation snapshot. The telephoto view from the volcanic caldera above a sea of clouds also captures an elusive green flash near the Sun’s upper limb. Atmospheric layers with sharp temperature changes cause the colorful flash as the Sun rises behind a distant cloud bank. Refraction along sight lines through the layers creates multiple distorted images of the Sun, and for a moment, can visibly deflect shorter wavelength green light.

🌅 於2023年3月20日，從毛伊島的哈雷阿卡拉（Haleakala）山頂上拍攝的地球第一縣春日出景象，這張假期快照捕捉到了令人難以捉摸的綠色閃光，閃光位於太陽上邊緣。從火山圓形谷地遙望雲海，氣層中的急劇溫度變化導致了這道色彩斑斕的閃光。光線在這些氣層中折射，使太陽出現在遠處雲層之後的時候，形成多個變形的太陽影像，瞬間可視地偏折較短波長的綠光。
