408 EXPEDITION TO POINT BAIJROW, ALASKA. 



risen to the position of the middle of the former zone, while incipient .sinuous and convoluted bands 

 were developing: in the E. from Hydra through Leo aud Coma Berenices. At 5 there were two 

 faint, quiet bands (brightness 1), one through Cygnus, Cassiopeia, Auriga, Gemini, and Cancer, and 

 the other through Leo Minor, I'rsa Major, and Draco. At C there was a quiet band (brightness 

 to 1) from Canis Minor through Oriou, Taurus, and Aries. At 7 there were traces of a faint band 

 from the W. to N W., and :it H Taint traces iu the SW. The last traces were seen at 9.10 a. in. Tho 

 magnetic needles were practically undisturbed all night. 



Dnrmbc,- 27rf2S, W.lZp.m. to 9.10 p. m. At 10.15 p. in. there was an arch in theNE. with its 

 curve at it Geminorum, altitude about 30, and extremities being NNW. to SE., passing through 

 Taurus, Gemini, Lynx, Leo Minor, and Coma Berenices. It was narrow, except in Coma Bere- 

 nices, where it was broken into 5 streamers. At 11.15 there was a band like a half arch, passing 

 through Gemini, Leo Minor, Coma Berenices, and Bootes (brightness 1), aud a faint streak from 

 Cyguus to Cassiopeia. At 12.15 a. m. there was an arch in theNE. through Orion, Gemini, Lynx, 

 Ursa Major, Canes Venatici. and Bootes, very broad in Ursa Major, with streamers iu Bootes 

 (brightness 1). This had risen at 1 a. m. into a broad zone (brightness 1), with its bands very 

 sinuous and broken and in motion across the zenith from the NNW. to the ESE., the extrem- 

 ities rising from the haze. The western edge ran through Orion, Taurus, Andromeda, Pega- 

 sus, and Cygnus, and the eastern through Gemini and Ursa Major. At 1.15 it was <]tiietcr 

 and narrower, being confined to the part west of the zenith. The aurora was still in tho 

 form of a zone at 2 a. m.. with its starting points in Monoeeros ESE. and Hercules XNW. 

 It consisted of three main bands. The western and brightest (brightness 1 to 2) band was 

 in rapid waving motion, and ran through Orion, Taurus (not inclosing the Hyades or Pleiades), 

 Perseus, Cassiopeia, Cepheus, close to 6 Cygni and Lyra, the eastern barely reaching Gemini and 

 Ursa Major. At 2.15 it was quieter and spread about 15 each way. At 3 the zone still continued 

 (brightness 1 to 2), with its starting points in Mouoceros ESE. and Aquila XNW., stretching west 

 to the square of Pegasus and east to Canes Venatici, with additional bands in the NE. through 

 Leo, Coma Berenices, and Bootes. It was quiet and brightest iu Cygnus. At 3.15 it was in tho 

 name position but paler (brightness to 1) ; 4 a. in. showed only traces of the extreme east and 

 west bands, but at 4.15 the eastern traces had developed into convoluted bands (brightness 1) 

 through Leo, Coma Berenices, Bootes, and Corona Borealis. At 5 there were only traces over the 

 horizon from NW. to SE. At (5 there were two motionless bands (brightness 1), one through Pe- 

 gasus. Perseus. Cassiopeia, Camelopardalis. and Lynx, and a short band from Ursa Maj or to Bootes. 

 At 7 a.m. there was a baud (brightness to 1) from Pisces through Aries, the Pleiades, and Orion 

 through Canis Minor. At 8, 9, 10, aud 10.10 a. m. there were still faint traces. The horizontal 

 force read high during the early part of the evening, aud was somewhat agitated at 2 aud 3 a. in., 

 while at and 7 there was a lively disturbance, the force falling too low to be read. The other 

 elements were slightly or not at all affected. 



l>rccmbcr 28 </W29, 1SS2, 11.10 p.m. to'2.1'2p.m. Though the sky was completely covered with 

 clouds at 11. 10 p. m., bands of aurora, which must have been very bright, appeared across the zenith 

 from NW. to SE. in rapid sinuous motion. At 2 a. in. the sky was partially clear, and broad diverg- 

 ing bands (brightness 1), radiating from Cygnus in NW., stretched across zenith towards the SE. 

 At 2.15 a bank of clouds about 15 high lay along the western hori/on, and above this nearly to tho 

 zenith the sky was covered with almost parallel broad band:; from theNW. to the SW. The lowest 

 resting on tho banks of clouds was the brightest (brightness 2 in NW.), and tte highest brightness 

 (1) ran through Cygnus, Cassiopeia, and Leo, ending in the clouds. At 3 portions of bright bands 

 could be seen through the clouds in the NW. aud SE. at an altitude of abo8t40 At 3.15 abroad 

 bright baud could be seen across the zenith from NW to SE. through the haxy clouds. At 1 there 

 weie broad haxy bands across the zenith from NW. to SE., apparently in motion, but much ob- 

 i-cmed by haze, and also a brighter band lower in the W. All was obscured by haze at 4.15 except 

 traces oftlie last band. No more was seen till 7, when the clouds partially cleared again, and a 

 broad band (brightness to 1), and motionless, through Lyra, Corona Borealis, Bootes, and Coma 

 Berenices, was visible. At s the, sky was wholly clear, and two or three bands (brightness 1 to 2), 

 with streamers, some of them reaching the y.euith and all vibrating rapidly from W. to E. Their 

 color was yellowish, and they occupied Taurus, Orion. Auriga, Camelopardalis, Gemini, Lynx, Leo,
