Note 401 — THE THIRD VOYAGE NORTH-WARD TO THE KINGDOMES OF CATHAIA and China, in Anno 1596.
Reading edition
This makes the date to have been the twenty-fifth of January. On the 24th, the sun was only in the fourth degree of Aquarius. And all the details furnished by the author concur in proving, that, in spite of his assertion of extreme precision as to the date, the conjunction of the moon and Jupiter,—and, inferentially, the first appearance of the sun also,—took place on the 25th of January, instead of the 24th, as stated.
On January 25th, at midday, when the sun’s longitude was 305° 25′,1, or 5° 25′,1 of Aquarius, its declination was—18° 57′,4: consequently, its centre was 4° 42′,4, and its upper edge 4° 26′,4, below the horizon. The mean refraction at the horizon cannot, however, be estimated at more than 34′9, or, with an assumed temperature of -8° Fahren., 39′,3; so that the extraordinary and anomalous refraction amounts to no less than 3° 49′. ↑
