From the Anglo-Saxon Chronicle entry for 891:
And this same year after Easter, around “going days” [Rogationtide]*
or earlier, appeared the star which men in book-Latin call “comet.”
Likewise men say in English that it is the “haired-star,” because
there stand out long beams of light at times on one side and at times on the
other side.
* “Rogationtide” is a church festival in which the fields and animals
are blessed. It can occur any time from late May to late July, depending upon
the date of Easter.
