424 EXPEDITION TO POINT BARROW, ALASKA. 



i-r.ibly obscured from the SK. to N\V. through Polaris could be seen. At 4 there were traces near 

 the zenith, but ;it 1.1. "i the haze was nearly .none, displaying extensive bands forming a sort of 

 vortex. One broad band (brightness 2) began in the top of (\vgnns, in the "NX I-:., as an irregular 

 clond.v patch, and passed round through Lyra, Hercules, P.oiites, Canes Veiiatici, I'rsa Major. 

 Lynx and Auriga, ending in IVrsens, whence .just below the edge of this a double band (bright- 

 ness 1) ran back to Gemini. There was also a broad band (brightness L', somewhat obscured by 

 clouds on the. SW. horizon through Orion. At 5.15 one band of streamers passed through Lyra, 

 Hercules. Corona Horealis, Bootes, and Coma Berenices, and another from Pegasus through 

 Arii s. Orion, and Gemini to Cancer, but vibrating slowly from K. to NY. (brightness ~2). 



At <.1"> a quiet band (brightness (I to 1) ran from Pegasus through Cygnus, Vtdpec-ula, and Ser- 

 pcus. At 7.15 a quiet yellowish zone t brightness 1 to -j tilled the southern half of the sky, and 

 one outlying band from Ursa Major to Cygnus in rapid, waving motion. At S.15 there were, seen 

 traces of a corona covering the whole sky from the horizon, centering a little south of the- zenith. 

 At 9,15 there \\ere four broad bands (brightness 1) covering most of the sky, the lirst in the north 

 from N\V. to NK.. with the crown at an altitude of about 11'". the second from ."K. to AY. through 

 Polaris, the other two starting together from the KSK., the, west one passing through Hercules 

 and Trsa Major, and the other through Corona Borealis, Canes Venatici. and Leo Minor, with 

 also a broad band of luminous patches from the KSK. to \Y. about l."P above the southern horizon. 

 At 10.15 there was a zone of three bands (brightness to 1). with its starting points KSK. and 

 NNNY., one through Lyra, Draco, t.'rsa- .Major. Lynx, Gemini, and Oanis Minor, the second through 

 Corona Borealis, (Janes Venatici, and Leo Minor, and the third through Serpe'ns, Bootes, Coma 

 Berenices, and Leo. At 11.15 there was a white, quiet arch from the NAY. to E. through Auriga, 

 Cassiopeia, and Lare.rta (brightness to 1), with streamers at the extremities, and also short 

 curved streaks in the south in Bootes, Hercules, and Coma Berenices, and a broad broken baud 

 from the SE. to SAY. about 10 above the southern horizon, all of the same brightness. The 

 weather then became too thick for further observation. A violent disturbance, atfecting all the 

 magnetic elements, commenced about L' a. in. and lasted about twelve or thirteen hours, being spe- 

 cially violent at - and s a. m. and 1 p. m.

 the wind reaching 54 miles an hour, with the drifting snow rendering accurate observation of the 

 aurora impossible, though the sky frequently was almost clear of clouds. Hazy light was observed 

 in the NE. at 12.15 a. m.. and bright traces in the XE. at 1 a. m. At L' a. m. there was a broad 

 zone across the zenith from the NAY. to SAY. (brightness apparently 1). At the next two observa- 

 tions the sky was completely covered with clouds, and traces only were seen near the zenith at .'! 

 a. in. and in the SK. at I. At 5 the sky was clearer, showing a band (brightness (I to 1) from Can- 

 cer through Canis Minor. Orion, and Taurus. At <i a brighter band (brightness 1) ran from 

 Leo. through Gemini, Auriga, and Taurus to Aries. At, 7 there were two yellowish bands (bright- 

 ness 1 to :_' . the lirst from Leo. thivugh Lynx, Camelopardalis and Cassiopeia, to Andromeda, 

 and the second from Cygnus, through Draco to I'rsa Major. At S there were merely traces round 

 the southern horizon and a few patches in the AN". At Jl.15 there was a broad white band on the 

 southern horizon, with si reamers in Scrpens and lioiites. There was besides awhile arch from 

 the SK. to NW. through Corona Borealis, Draco, Ursa Major, Auriga, and Orion, and a similar 

 band from K. to N. through Sagilta, A'nlpccula. Lacerta, and Andromeda, and streamers in Pleia- 

 des (brightness 1). At 10.15 a band ran along the northern horizon from the NNY. to KNK., 

 and a striated band from the SE. to NAY. through Hercules, Draco. I'rsa Major. Lynx. Cancer. 

 Gemini, and Canis Minor. There was also a broad band near the southern horizon from SK. to 

 SNY. There were, also streamers in the E. All were white and quiet (brightness o to 1 . This 

 was essentially unchanged at 11.15, after which the sky again became overcast. A violent dis- 

 turbance began at 3 a. m. and lasted all night.

 with its extremities bearing KSK. and NNNY., and its crown at an altitude of about .-15 . The
