[漢羅] 北半球 ê 四分儀座流星雨

四分儀座流星雨這个名是 ùi 一个 去予人放袂記 ê 星座 來 ê，伊逐年攏會為北半球 ê 觀星者表演一擺。 這个流星雨 tī 天頂 ê 輻射點 是踮一个老甲已經無咧用 ê 名，四分儀座 內底。 彼位離北斗星群袂傷遠，就踮現代星座 牧夫座 kah 天龍座 ê 交界。 北斗星群，有一寡人嘛 kā 叫做 牛犁。 這个星群 ê 湯匙仔柄,就 tī 這幅圖 ê 正爿頂懸附近，流星雨 ê 輻射點就 tī 伊下底。 北極星 就 tī 倒爿頂懸遐。 Tī 這个南韓長水郡 ê 夜空景色內底，只要綴天頂 ê 光巡行到輻射點，就知影這个是四分儀座流星雨。 相片是 tī 2024 年 1 月 4 號流星雨上強 ê 幾若點鐘內翕了了後，才 kā 疊出來–ê 合成影像。 四分儀座流星雨 ê 塗粉來源，tī 2003 年 ê 時陣就認為講，可能是 ùi 一粒小行星來 ê。

[English] Quadrantids of the North

Named for a forgotten constellation, the Quadrantid Meteor Shower puts on an annual show for planet Earth’s northern hemisphere skygazers. The shower’s radiant on the sky lies within the old, astronomically obsolete constellation Quadrans Muralis. That location is not far from the Big Dipper asterism, known to some as the Plough, at the boundaries of the modern constellations Bootes and Draco. The Big Dipper “handle” stars are near the upper right corner in this frame, with the meteor shower radiant just below. North star Polaris is toward the top left. Pointing back toward the radiant, Quadrantid meteors streak through the night in this skyscape from Jangsu, South Korea. The composite image was recorded in the hours around the shower’s peak on January 4, 2024. A likely source of the dust stream that produces Quadrantid meteors was identified in 2003 as an asteroid.
