This
stamp appears in a set commemorating the appearance of Halley痴 comet
in 1986. The Danish astronomer, Tycho Brahe, observed the comet of
1577, which was not an apparition of Halley痴 comet, from his
observatory at Uraniborg on the island of Hven. This stamp shows notes
and a sketch of that comet by Brahe. The caption of the stamp and
another stamp in the series have been exchanged. It should read:
典ycho Brahe痴 notes and sketch佑omet of 1577."
