414 EXPEDITION TO POINT BARROW, ALASKA. 



from E. to NNW. mid a similar band from SE. horizon through Leo to Canis Minor. A third, 

 narrower band, ran from E. to \V. close to Ursa Major. There were faint streamers in Lyra, 

 Cygnus, Laeerta. and Cassiopeia, also S. in Bootes, Coma I'.ereniees, and Leo Minor, faiut, white, 

 and quiet. There were bright (brightness 2) streamers in the W. and NW. in Taurus, Pleiades, 

 Perseus, and Auriga. They were rose-eoloreil and vibrating rapidly. At 10.17 there was a broad 

 faint white band on the southern horizon, and a baud across the' /enith SE. to NW., white and 

 quiet (brightness to 1) At 1 1.17 there was a broad, quiet, white arch (brightness to 1) from 

 E. to W.. through Corona Borealis, Ursa Major, and Gemini. At 12.17 p. in. there were ,'i -such 

 bands, one through Polaris and the lowest at an altitude of about -lu 3 . At 1 p. in. these bauds 

 (brightness to 1) started together from Gemini and ran as follows: One, the broadest and 

 brightest, through Leo Miner, Bootes, Corona Borealis, and Hercules; one thr6*ugh Ursa Major, 

 Draco, and Cygnus, and one through Ursa Minor to Cyguus. These bands were constantly 

 shitting, rising towards the zenith and then receding southward. The last traces were seen near 

 the /enith at 2.12 p. m. The magnetic needles were quiet up to 9 a. m., when the horizontal force 

 began to fall, culminating in a disturbance at 1 p. m., with very low 'horizontal force, high easterly 

 declination, and almost undisturbed vertical intensity. 



January 9 and 10, 11.15 p. m. to I p. m. At 11.15 there was a lia/y light in the NIC. which de- 

 veloped into a faint pale arch, and faded completely before midnight. At 1 a. in. there was a 

 pale glow in the NE. At 2 there was an extraordinary zone parallel to the magnetic meridian 

 instead of at right angles to it as usual. It was so pale as to be scarcely perceptible. The si. 

 ing points were in Coma Berenices NIC., and Pisces S.W., extending in breadth from the lower 

 part of Draco to Tauri. At 2.15 theie was an arch in the NE. (brightness 1), across the base of 

 the zone, through Leo, Ursa Major, Canes Venatici (including) Boo'tis, Corona Borealis, and into 

 Hercules. The sky then suddenly clouded over and remained cloudy until G, when it cleared, and 

 there was a faint band (brightness to 1) from Bootes through Corona Borealis, Lyra, and Cygnus, 

 and another from Pegasus and Andromeda to Cassiopeia. At 7 there was a quiet, bright band 

 from Leo through Cancer, Gemini, Orion, and Taurus. The sky then became again overcast, and 

 continued so until 12.10 when it was clear, and a few faint traces were observed near the zenith. 

 At 1 the last faint traces were seen in the S. in Bootes and Canes Venatici. The magnetic needles 

 were, comparatively quiet all night. 



.January 10 and 11, 10.15 # to 7 a. m. At 10.15 p. in. there was a faint band of light in the 

 NE. nearly parallel to the horizon and about 20 above it. At 11.15 this had developed into a 

 low arch (brightness 1) with its extremities bearing NNW. and ESE. passing through Canis 

 Minor, Cancer, Leo, Coma Berenices, and Bootes, sending up streamers in Bootes. The altitude of 

 the erown of the arch was about 15 C . At 12.15 a. in. it was reduced to a few very faint streamers 

 in the NE. At 1 there was a very faint arched segment in the S\V. There was a similar trace in 

 the west at 2, also in the SE. at 2.15. At 3 there was a pale glow fading insensibly into the sky 

 with a well-defined dark segment below it, lying close to the horizon, from E. to SSW. At 3.15 

 the whole sky appeared to be covered by the palest possible broad bands, separated by narrow 

 dark spaces, parallel to the magucti* meridian and appearing to converge in the NE. and BW. 

 There were slight traces at 4. At 5 a pale, yellowish band (brightness to 1) ran through Bootes, 

 Corona Borealis, Hercules, and Lyra to Sagitta. At 6 there were mere traces in the N., but at 7 

 a broad, quiet band stretched from Pegasus through Andromeda, Cassiopeia, Ursa Minor, I 

 Major, and Canes Venatici. This was the last seen. The magnetic needles were unusually quiet. 



January 12, ISS3, 1 a. m. to 1 p. m. At 1 a. m. there was a quiet, regular, and narrow arch 

 (brightness 1) from the ESE. in Monoceros to the NNW. in Serpens, through Leo (//.Leonis), Leo 

 Minor, Ursa Major, just above aCanuin Veuaticorum, Bootes, and Corona Borealis. At 1.15 it 

 was broader and somewhat sinuous. At 2 there was only a partial arch (brightness 1) from the 

 KSE. in Hydra, through Leo (oLeonis) and Coma Berenices ending in Bootes at an altitude of 

 about 20. This was fading at 2.15. At i5 and 4 the western horizon was obscured by haze, and 

 traces only were visible. No aurora was seen at 5, but at G a quiet band (brightness 1) stretched 

 from Andromeda, through Perseus, Auriga, Gemini, Cancer, and Leo. At 7 a similar band ran 

 through Cygnus, Lyra, Draco, Ursa Major, and Leo. At 8 there were simply traces in the N. At 

 10,10 ilieie were traces in the E. and SE. and again at 11.10 in the NE. At 12.10 there was a
