승정원일기(承政院日記)와 조선정조시대(朝鮮正禮時代)의 천문관측기록(天文觀測記錄)

ON THE ASTRONOMICAL RECORDS MADE IN THE DAYS OF KING JEONGJO OF YI DYNASTY

Astronomical records in the days of King Jeongjo of Yi dynasty, 1777-1800, are examined for solar and lunar eclipses, meteors and comets. The books used for this investigation are Sung Jeong Won Il Gi, which are the original daily records written in the court. The records found in these Sung Jeong Won Il Gi are tabulated according to the four astronomical phenomena above, and they were cross checked with the records in the book, Jung Bo Mun Heon Bi Go. Although Jung Bo Mun Heon Bi Go has most frequently been used as the original records to those who work for the ancient Korean records, the inaccuracy and the deficiency are found.
