Last night, a very singular Aurora was seen here. A little before 8
o'clock, the northern lights were observed, in their usual appearance, verging
towards our zenith from the N. N. W. point, the magnetic north; but these
gradually disappearing, a well defined zone of light, by many degrees more
brilliant than the milky way in it's brightest state, was suddenly formed across the
whole Heavens, pretty nearly in a direct line from west to east: it seemed to
emerge from the west, whence it extended itself rapidly eastwards and to be
about 3 (o) in breadth; it varied it's situation very perceptibly, but in general
the centre of this magnificent arch was nearly vertical to us.

       The southern edge continued unbroken about half an hour, but it's
northern one was frequently much indented, and at intervals appeared to dart rays
northwards in a stream-like manner. It afterwards frequently separated into
irregular parts, and varied in breadth in some places, from 3 (o) to perhaps 7
(o) or 8 (o), but a little before nine was nearly as entire as ever; and about
half past nine it disappeared altogether. The atmosphere, though a little
cloudy in the western horizon, was remarkably clear all evening.
