Meteorological Observations for November 1830. 79 



AURORA BORE ALES. At 9 o'clock in the evening of the 1st instant, a 

 bright aurora borealis appeared between the North and West, behind a 

 low cirrostratus cloud, which it enlightened in some attenuated places, and 

 several very bright patches were seen in the horizon. At 18 minutes 

 past nine the first column of light emanated from it (whose bearing was due 

 North) to an altitude of about 16 degrees, and was succeeded by ten or 

 twelve more perpendicular columns of various breadths between that point 

 and the magnetic north during a peculiarly bright moon-light, the moon's 

 altitude being from 25 to 30 degrees, and only 28 hours beyond her opposi- 

 tion with the sun. Jt has been much doubted whether the coruscations 

 of an aurora can be seen in this latitude after the first, or before the last 

 two or three days of the moon's age; but in this instance the strong 

 lunar light had but little influence in diminishing the splendour of these 

 flame-coloured columns. The sky became overcast by 10 o'clock, and 

 did away its appearance. 



At half-past seven in the evening of the 4th, an aurora was observed 

 between the North and West, and increased in brighness till eight, when 

 two bright columns of light rose from it, about North-west by West, to an 

 altitude of 22 degrees. Several other columns successively rose between 

 that point and the true North till a quarter past eight, at which time the 

 moon began to rise, but the steady light of the aurora did not disappear 

 till nine. Two bright trained meteors appeared over it, and the thermo- 

 meter rose one degree. A faint aurora appeared in the evening of the 

 7th, from 7 till 10 o'clock, without any coruscations; and two meteors 

 appeared over it.
