30 RECORD OP AURORAL PHENOMENA. 



14th. At llh. 30m., a faint low band proceeded from 110° to 178°, elevated 8°, and another at a 

 hi "-her elevation from 121° to 212°. These streams crossed each other in the bearing 155°; 

 and it may be remarked that this is the only occasion on which I have seen the streams to cross 

 each other. They separated before midnight; the eastern one ascended some degrees higher, 

 but the other remained in the same state. Cloudless sky. 

 15th. At 9h. p. m., Aurora crossed the zenith from 257° to 16°. None visible at midnight, yet 



the needle had moved forty minutes westward. 



18th. At 9h. p. m., Aurora gleamed through the horizon in a continuous arch from 279° to 99°. 



19th. At 8h. p. m., Aurora appeared to the eastward in five arches, having the same extremities 



at 88° and 219°. The upper arch crossed the zenith, and the others were elevated between 



15° and 20°. At midnight, two concentric arches appeared through the haze, lying across the 



zenith; their extremities bore 65° and 245°. The needle then pointed to 348° 5', having 



moved 40° eastward. At 12h. 25m., a broad and more brilliant arch crossed the zenith, from 



133° to 313°; the needle then moved westward 1° 5', to 349° 10'. This change is a further 



confirmation of the observations on February 13th. 



20th. At 9h. p. m., beams of light issued at 99° and pointed towards the zenith. At 10b. 30m., 



a brilliant arch from 99° to 219°, elevated 80°, a small arch in the zenith, and several beams at 



219°. At midnight, several beams arose parallel to each other between 335° and 349°. In a 



few seconds, flashes were emitted from them, which first darted to the zenith, and then, twisting 



round, shot towards a stream that had proceeded at the same instant from 212°, which they 



joined. The coruscation now resembled an irregular horse-shoe, composed of many slender 



beams of brilliant light. This display soon passed off to the eastward, having descended to the 



horizon before it disappeared. The needle was not in any way disturbed after nine, from which 



circumstance I am induced to suppose that the Aurora was very distant. We seldom witnessed 



a greater variety of arches, beams, and flashes than were displayed this night, both in the 



horizon and zenith. If these coruscations had passed as near to the earth as they appear to 



have done at other times, some effect, I conceive, would have been produced on the needle. 



The sky was cloudless. 



On the following morning, it was perceived that the needle had receded two degrees eastward, and 



it did not regain its usual position before 4h. p. m. At 8h. p. m., a horizontal band of faint 



light extended from 88° to 245°, elevated 7°, which remained almost stationary until midnight, 



at which hour two brilliant arches appeared, whose united extremities bore 279° and 76°; and 



a faint broad arch traversed the zenith from 279° to 88°. Needle moved eastward. Shortly 



afterwards, the horizon was encircled with an illumiuated zone, and the northern part of the sky 



covered with Aurora. 



22d. At 9h. p. m., a continuous arch across the zenith from 279° to 99°; the color pale yellow. 



Needle moved westward. 

 23d. At 9h. p. m., a low band, parallel to the horizon, extending from 302° to 346°, patches at 

 76°, and some faint streams in the zenith pointing to 234° and 54°. The needle had moved 

 eastward. At llh. 15m., a broad brilliant arch extended from 29° to 99° across the zenith, 

 reaching to each horizon. The needle had, since 9h., receded 24' westward. At midnight, 

 two arches appeared; one from 54° to 324°, elevated 50°, the other from 234° to 144°, 

 elevated 12°. 

 24th. At 9h. p. m., a continuous arch, through which the stars were distinctly visible, passed from 

 99° to 279° across the zenith, and a beam appeared parallel to this, proceeding from 99°, which 

 terminated in the zenith. At midnight, two belts of brilliant light extended from 99° — one by 

 the south and west, the other by the north — which encircled the horizon at an elevation of 20°, 

 except between the points 324° and 322°. No perceptible disturbance of the needle. 

 26th. At midnight, a brilliant arch issued from 313° and reached to 99°, the centre being elevated 

 20°. At the latter point, the coruscation curved upwards, and was then prolonged across the 

 zenith to 200°. The stars shone through this stream with undiminished brilliancy. The needle 

 moved a few minutes westward. 

 27th. At 9h. p. m., two arches crossed the zenith from 76° to 279°, very broad and brilliant; the 

 stars were distinctly visible through them. At midnight, the Aurora was diffused over a great
