Consideratio & observatio cometae aetherei astronomica qui anno MDLXXX mensibus octobri, novembri et decembri in alto aethere apparvit

...that it was turned away from the Sun, although it did not have it exactly diametrically opposite. From which I could easily be persuaded that this tail did not finally accrue to it on the 9th, about which, however, we dwelling on earth could see nothing, since it raised it directly upward into the sky; for the Sun and the Comet were in opposite places of the zodiac. But as it itself receded from the diameter of the Sun, it began to deflect it more and more toward our sight. Thus, I would not want to deny that the new Star of the year 1572 was similarly tailed, but since its distance, as well as that of the entire star-bearing sphere in which it was situated, was so great that the entire distance of the Sun and the Earth is not felt in relation to it, as Copernicus asserts, its tail certainly did not appear to us on earth extended upward.

Initially, this comet rose after the setting of the Sun and again went below the horizon in the morning before twilight. But when the tail was added to it, it itself rose above the horizon before the setting of the Sun, but it set in the early morning, a little after the 3rd hour of the morning. The tail looked toward the equinoctial rising. But the more it was elevated and ascended into the north, the more it deflected the tail into the north, until finally it was driven toward the pole in both the evening and morning hours.

OBSERVATIONS OF THE MOTION AND APPARENT PLACES of the Comet, made by the Astronomical Staff.

CHAPTER III.

A decorative drop cap letter S.But the motion of this comet, instituted by this crude and merely ocular observation (although this had to be done first), cannot yet satisfy the proposed business. It is indeed common for many, and indeed for those who dare to boast that they are great and wise mathematicians (they perhaps seem such to themselves)...
