EXPEDITION TO POINT BARKOW, ALASKA. 401 



through breaks in the clouds iu the N. At 2 p. in. there were still traces in Auriga and Gemini. 

 There was another magnetic disturbance between 11 ;i. in. and 2 p. in., tin- horizontal force fulling 

 low. 



December 9 and 10, j. m. to 11.10 a. m. At 9 p. in. the aurora began as a faint band in tho 

 E. in Taurus, Gemini and Lyra. At 10.15 there was an arch from Taurus through Orion, Gemini, 

 Cancer, Lynx and Leo Minor to Coma Berenices. It was very faint, except in Taurus, Coma 

 Berenices and Leo Minor, and in the latter constellation was broken into streamers, brightness 1. 

 At 11.15 there was merely a taint arched streak through Cancer, Gemini and Lynx. At 12.15 a. m. 

 the faint arch was in nearly the same position, but extended through Orion, Cancer, Leo Minor 

 and Coma Berenices. There were also two stationary streamers (brightness 1) in Coma Berenices 

 and Canes Yenatici. At 1 a. m. the pale arch (brightness 1) extended from Orion's belt in the S.E. up 

 through the lower part of Gemini, Leo Minor, Lynx, Canes Veuatici and Bootes, ending below Bootes 

 in the N. It was much paler at 1.15. At 2 a. in. there was in the E. a belt of two or three pale bands) 

 the third and lowest very indistinct, starting from a point in Monoceros in the, ESE. near, but not 

 on, the horizon, through Gemini, Lynx and Ursa Major to Bootes in the N. (brightness 1). At 2.15 

 it was condensed to a single band (brightness 2), the lower end passing through Canis Minor, Leo 

 Minor and C:uies Veuatici to Bootes. It was brighter iu the ESE. From 3 to 3.15 there was an 

 arched, slightly sinuous, band from a point iu Hydra low in the ESE. through Leo, Coma 

 Berenices and Bootes to a point in Hercules in the NNW. where it sent up a pale streamer into 

 Draco. It was somewhat convoluted in the ESE. (brightness 1). At 4 to 4.15 an arched band (1) 

 starling low in Leo in the E. ran through Coma Berenices and faded out high in Bootes in tho 

 NNK. It was fading slowly, and there were also traces in the S. At 5 two short bands 

 (brightness to 1) extended from Pisces through Triangnliuu to Perseus, and the other from 

 i Vyasus through Cyguus and Lyra. At G there were merely traces on the southern sky, but at 

 7 a band of streamers (brightness 2 to 3) in rapid motion from AV. to E., and changing color from 

 yellow to green and red, extended across the western sky through Pisces, Andromeda, Perseus, 

 Auriga, Taurus and Orion to Canis Minor. At 8 there was a quiet yellowish arch from Pegasus 

 through Cygnus and Draco to Bootes high iu the NE.; 9.10 a. m. showed a broad, low, quiet, white 

 arch on the southern horizon from the SSE. to YVNW., with a segment of an arch in the north 

 and a quiet corona of faint white streaks at zenith. The arch in the S. was still visible at 10.10, 

 but the aurora had faded to mere traces at 11.10. The magnetic needles were comparatively quiet 

 all night, though both horizontal and vertical intensity read somewhat higher than usual. 



!>('<-aitber 11, 1882, 2 a. m. to 2.10 p. m. At 2 a. in. a broad band (brightness 2) showed across 

 Hie zenith from NW. to SE., while the clouds were still so thick as to allow but one or two stars 

 io lie seen. This was wholly gone at 2.15, but there were traces of a similar band at 3, which was 

 imiel* brighter and better defined at 3.15. At 4.15 broad, bright, shifting, and sinuous streaks in 

 rapid motion across the zenith. This must have been a very brilliant aurora, as it showed brightly 

 1h rough the clouds and was accompanied by a large magnetic disturbance, with decreased intensity 

 and increased declination. After 8 a. in. the sky cleared, but only traces were observed (at 10.10 

 a. m.) until 1 p. m., when there was a pale (0 to 1) zone of live distinct Kinds running N"W. and 

 !SK. ; two of them from Gemini to Bootes, one through Leo Minor, and the other through I'rsa 

 Major, two from Auriga to Corona Borealis, one through Ursa Minor, and the other through Cas- 

 siopeia and Cephcus, and the fifth from Perseus to Hercules through Andromeda and Lacerta. 

 The middle band was the brightest. At 2 a. m. there were faint traces at the zenith, which were 

 wholly gone at 2.12. Besides the disturbance already mentioned there was a lesser one just before 

 and during the zone aurora last noted. 



December 11 and 12, 1882, 9.15 p. m. to 1 p. m. At 9.15 p. m. an arch surmounted by streamers 

 extended from Cetus through Taurus, Auriga, Gemini, Cancer, Lynx, and Leo Minor. It was very 

 faint, except iu Taurus, where the streamers reached a brightness of 2, with the light constantly 

 varying in brilliancy. At 10.15 a similar arch extended through Taurus, Orion. Gemini, Cancer, 

 Leo Minor, Leo, and Coma Berenices to Bootes, with a brightness of 1, except at the ends, where 

 it was 2. There were also faint bands extending, one through Bootes, Draco, Cepheus. Cas.Mopeia, 

 Andromeda, and Pisces, and the other through Corona Borealis, Lyra, Cyguus, Pegasus, and Pisces 

 with a large mass of luminous haze in the SW., extending from Bootes to Aquila. There was little
