[漢羅] 地球烏影 ê 交界

地球 ê 中央烏影，嘛叫做本影，是圓 ê。 Tī 天頂若是倚地球愈近，這个圓 ê 烏影 to̍h 愈大，若離地球愈遠，這个圓 ê 烏影 to̍h 愈細。 若是 tī 月球軌道 ê 所在，這个烏影是比月球較大。 毋閣 tī 11 月 18/19 ê 月食，有一屑屑仔 ê 月娘留 tī 本影 ê 外口。 這張相片是 tī 1.5 點鐘 ê 時間內底，kā 這擺 99 葩 ê 月全食 翕著 ê 5 張相片疊做一張 ê。 這个系列是 kā 月食 按照 去予地球 圓形 烏影閘著 ê 部份排好勢。 上中央彼張是「食甚」，就是「食」發生上濟 ê 時陣。 你會當看著月娘 tī 地球烏影外口猶是遮爾光，敢若是一个薄薄 ê 銀盤。 是講，tī 地球烏影內底 ê 月球嘛毋是全烏 ê，你猶是會當看著紅色 ê 反射光，這是 一部份色光 ê 太陽光 去予地球大氣層 kā 散射到 地球烏影區，才產生這款現象。

[English] At the Shadow’s Edge

Shaped like a cone tapering into space, the Earth’s dark central shadow or umbra has a circular cross-section. It’s wider than the Moon at the distance of the Moon’s orbit though. But during the lunar eclipse of November 18/19, part of the Moon remained just outside the umbral shadow. The successive pictures in this composite of 5 images from that almost total lunar eclipse were taken over a period of about 1.5 hours. The series is aligned to trace part of the cross-section’s circular arc, with the central image at maximum eclipse. It shows a bright, thin sliver of the lunar disk still beyond the shadow’s curved edge. Of course, even within the shadow the Moon’s surface is not completely dark, reflecting the reddish hues of filtered sunlight scattered into the shadow by Earth’s atmosphere.
