400 EXPEDITION TO POINT BARROW, ALASKA. 



\vas filled with bands which united with the first in the SE. and XXW. (brightness to 1). At 

 10.17 nothing remained but traces of the arch in the southwest. At 11.17 the southern horizon 

 was mottled with taint, white spots, and at the, same time a band of white, quiet light (brightness 

 to 1) passed from the N\V. horizon through the Pleiades and Gemini a short distance southeast 

 of Ursa Major. At 12.10 p. m. there was an extensive aurora of parallel bands, white and quies- 

 u-nt, running ESE. and XXW., and extending from the southern horizon to a point about 15 

 north of Cassiopeia. The aurora was unchanged at 1 p. m. but had faded to traces at 1.15. The 

 n:agnetic needles were somewhat disturbed from 11 a. m. to 1. p. in., the horizontal force being 

 diminished and the declination and vertical force increased. 



December 8, 1882, 3 a. m. to 10.15 a. m. There was a faint glow along the horizon as the twi- 

 light faded, and at 3 a. in. there appeared faint traces of streamers in the ESE. below Procyon. 

 At 4 a. in. there was a somewhat sinuous white and quiet band (brightness 1) from a point in 

 Hydra low in the ESE. up through Cancer, Leo Minor, Ursa Major, and Draco, ending near a 

 Lyrac in the NW. At 4.1.5 it was brighter (2) in the ESE., more sinuous, and spreading a little, 

 with an additional pale baud reaching to ft Cygni. At 5 a. m. a motionless band (brightness 1) 

 extended from Pegasus in the NW. through Aries, Taurus, and Orion to Canis Minor iu the SE. 

 This band Avas in the same position at G a. m. but brighter (1 to 2). At 7 a. m. bright bauds (1 to 

 2) extended from Yulpecula to the zenith and N. and E. of the zenith through Cygnus, Lyra, 

 Draco, Hercules, Bootes, and Ursa Major to Leo. No motion was noticed. At 8 a. m. a pale baud 

 (0 to 1) stretched from Andromeda through Perseus, Auriga, and Gemini to Cancer. At 9.15 a. m. 

 a broad, bright (1 to 2) band, white and quiet extended from Canes Venatici through Ursa Major 

 and Cassiopeia to Andromeda. At 10.15 traces only were visible and no more was observed. The 

 magnetic needles showed no signs of disturbance. 



December 8 and 9, 1882, 10.45 p. m. to '2 p. m. At 10.45 p. m. there was a faint (0 to 1) but 

 definite arch of streamers low iu the XE. in Gemini and Cancer. Nothing but a pale glow ou the 

 horizon was seen until 12.15 a. in., when there were bright streamers in Canes Venatici and Coma 

 Berenices, and three wavy bands, one through Taurus, the Pleiades, Perseus, Ursa Major, and 

 Bootes, the second through Taurus, Auriga, Ursa Major, and Bootes, and the third through Taunts, 

 Orion, Gemini, Leo Minor, and Coma Berenices. These bands were all pale except in Bootes, 

 where they readied a brightness of 2. At 1 a. m. there was a broad zone crossing a little SE. of 

 the zenith, with its starting points in Serpens in the NW. and Mouoceros in the ESE., the eastern 

 edge passing through Cassiopeia and the western through Cyguus and the square of Pegasus, 

 with considerable motion on the eastern edge. At 1.15 the whole of the sky from Pegasus in the 

 SW. to Gemini in the NE. was covered with serpentine bands and streamers, one starting from 

 Cygnus in the NW. and running towards the SE. through Cassiopeia to the Hyadcs, where it 

 turned on itself and ran -along the XI-]. sky through Auriga and Ursa Major, here blending into 

 rt bright mass of curtains and whorls in the X. There was considerable motion, both twisting and 

 vibratory, the whole moving westward rapidly. There were faint colors and a, brightness of 2 to 3. 

 The declination fell about a degree and a half. At 2 a. in. the western portion was nearly gone, 

 and the eastern formed three or four bands from Serpens through Ursa Major and Caues Venatici 

 to Gemini and Cancer, where they curled round into curtains (brightness 2). There was a magnetic 

 disturbance specially marked by a high horizontal force. At ."> a. in. nothing was left except faint 

 traces of a band from the same starting points across the zenith through Cassiopeia. The mag- 

 netic needles were nearly back to their normal position. At 4 a. m. these traces appeared as at 

 the last observation, and had ne.arly disappeared at 4.15, while a patch of aurora was beginning 

 to develop in the lower part of Leo, low in the NE. At 5 a. in. there were merely traces in the X. 

 At (i several yellowish-green bands extended from Pegasus through Triangulum, Aries, Taurus, 

 Orion. Auriga, Gemini, and Canis Minor to Cancer, with some quiet streamers in Cancer (bright- 



9 1). At 7 a. m. a zone of yellowish-white bands crossed the zenith through Cj'gnus, Cassiopeia', 

 I'd sens, Camelopardalis, and Lynx to Leo, with a rapid waving motion (brightness 1 to 2). At 8 

 a. in. there was a faint (0 to 1) motionless band through Hercules, Lyra, and Draco to Bootes and 



no Berenices. At 10.10 and 12.10 p. in. there were faint tiaces only visible. At 1.10 p. in. a 

 band (brightness 1) extended from Leo Minor through Ursa Major and Ursa Minor to CcpheusJ 

 and faint streaks ran from Gemini towards Ursa Major. Patches of aurora were also visible
