Aurora as seen near Manchester. 



interposition of clouds. The whole of the sky had an awful 

 appearance ; for the tinge of red which pervaded the whole 

 expanse, assumed, in many points, from the depth of colours 

 above, and the density of the clouds below, the dark copper 

 tint which is seen on the disc of the moon during a lunar 

 eclipse.

A splendid arch of a blood-red colour, ex- 

 tending from the east, south of u Aurigae, 

 by Perseus and the polar star, to near ct 

 Coronae Borealis, in the west, where a dense 

 cloud intervened, and rendered the termin- 

 ation of the arch at the horizon invisible. 

 The same appearance continues. 

 The colour extending to the zenith, and be- 

 yond to ol Aquilae. 



} Numerous streamers, which, but for the light 

 of the moon, would have been exceedingly 

 brilliant. The red colours now less in- 

 tense. 

 The colour almost disappeared in the N. e. 



}The altitude of the arch greatly reduced ; 

 the colour very intense, near to the stars 

 s, £, yj Ursae Majoris. 

 Streamers from the west, forming eventually 

 an arch of white light, from the horizon to 

 the meridian, a little south of a Aquilae, and 

 onwards until interfered with by the light 

 of the moon. 



!■ The colour now generally faint. 



}The colour very much more visible, espe- 

 cially in Lyra ; streaming from the west 

 to and beyond a Lyrae ; and a beam of red 

 light from the west by south, to a Serpentis. 

 The light, which is now less vivid, though 

 deepening at intervals, is more diffused, and 

 is a band 55° in breadth, from the zenith 

 towards the magnetic north. 

 The coloured light in the north scarcely visible, 

 but streamers of red and white light inter- 

 mixed from the west to within 10° of the 

 meridian. 

 A brilliant streamer of red light from the west 

 to the meridian, 18° south of the zenith.
