618 ON THE LUMINOUS ARCH, OR METEOR, 
arch to the south was observable; on looking I 
beheld a beautiful and brilliant well defined arch 
crossing the magnetic meridian at right angles;. 
its summit was 10°+ to the south of the zenith, 
about 4 or 5 degrees broad, and extending from 
about 20 degrees altitude east to 20 degrees 
west. It continued, without any sensible varia- 
tion in position, for about one quarter of an hour 
after I saw it, and it had been seen for a con- 
siderable time before eight. The star Almach 
(foot of Andromeda) was near the magnetic 
meridian, and the arch was as far above it as the 
breadth of the arch by estimation. The arch 
soon advanced to the south about 20 degrees and 
became fainter, but continued visible till half or 
three quarters past eight o’clock, when it entirely 
vanished. About half-past eight a bright falling 
star shot from the south-east along the line of 
the arch from east towards the west about 30 
degrees of altitude—its course was from 5 to 10 
degrees in extent. The Aurora in the north 
continued long after. 
The appearance of an auroral arch, such as 
was presented on the evening of the 3rd of 
November last, isa rare phenomenon. I do not 
remember to have seen more than one before,
