[漢羅] 北方 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 是踮一个這馬已經無咧用 ê 四分儀座。 彼位離北斗星袂傷遠，to̍h 踮現代星座 牧夫座 kah 天龍座 交界 ê 所在。 實際上北極星是 tī 這幅圖中心 ê 下底，北斗星群（嘛叫做 牛犁）踮伊面頂，正爿是流星雨 ê 輻射點。 這張相片是 2022 年 1 月 4 號流星雨上濟彼陣，用差不多幾若點鐘 ê 時間翕了了後，才 kā 疊做這張全景夜空圖。 綴天頂 ê 光巡行到輻射點，就知影這个是四分儀座流星雨。 前景 ê 陣列望遠鏡是踮中國內蒙古 Mingantu 觀測站 ê 中國電波太陽翕相光譜儀 望遠鏡。 產生四分儀座流星雨 ê 塗粉來源，tī 2003 年 ê 時陣認為講，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, at the boundaries of the modern constellations Bootes and Draco. In fact north star Polaris is just below center in this frame and the Big Dipper asterism (known to some as the Plough is above it, with the meteor shower radiant to the right. Pointing back toward the radiant, Quadrantid meteors streak through the night in the panoramic skyscape, a composite of images taken in the hours around the shower's peak on January 4, 2022. Arrayed in the foreground are radio telescopes of the Chinese Spectral Radioheliograph, Mingantu Observing Station, Inner Mongolia, China. A likely source of the dust stream that produces Quadrantid meteors was identified in 2003 as an asteroid.
