41G EXPEDITION TO POINT BAPJtOW, ALASKA. 



was a band in the S. side I'roin Corona Horealis. through Ursa Major, to Gemini, with a slight 

 fringe of streamers, and streamers in the I- 1 ,., X., and YV.. forming with the band in the S. a well- 

 tletined corona. There Mas no motion except a slight vibration of the streamers in the X. At 

 30.17 the areh on the southern horizon was still visible, but its streamers had faded. There were 

 laint streamers, quiet and white (brightness to 1), in the XE., in Sagitta and Cygnus, and in the 

 XN\V., in Triangnlum and Aries. At 11.17 then- was a quiet, faint, white arch on the southern, 

 horizon from ESE. to "VYNW. At 12.17 a narrow band (brightness 1) extended from KSE. to 

 AVXW., through Hercules, Ursa Major, Lynx, and Gemini, with luminous spots also in CygnusJ 

 Laecrta, and Cassiopeia. At 1 p. in. a band (brightness to 1 j ran from Aqnila, in the ESE.} 

 through Ursa Elinor, to Gemini, in the "WXW.. and the last, faint traces were seen at 1.17. The 

 magnetic intensity was slightly increased at 5 a. in., and there was a slight disturbance at 1 to 

 3 p. in. 



./itxwtry 15, 1883, 5.17 a. >n. to 12.17 p. m. At 5.17 a motionless band (brightness 1) crossed 

 the sky from XW. to ESE., west of the zenith, through Pegasus. Andromeda, Cassiopeia, Camelo- 

 pardalis. Ursa Major. Leo Minor, and Leo. At G.17 series of while curtains (brightness 1) with 

 gentle motion covered the sky from the eastern horizon to Auriga and Perseus in the, AY., and from 

 Leo Minor in the S. to Cygnus in the N. There were also luminous patches in Draco, IVgasusJ 

 Trianguhim, Aries, and Taurus. At 7.17 yellowish-green bands (brightness 1 to 2), waving slowly 

 fromW. to E., extended from Pegasus through Laeerta, Cygnus, Lyra, Hercules, Corona Lorealisj 

 Bootes, and Coma Berenices. At 8.15 a broad arch spanned the southern hori/on from ESK. to 

 AY., with its crown at an altitude of about 1~>. A broad band extended from the western cud 

 through Gemini and Leo Minor to Ursa Major, and a narrow irregular band from the EXE. throngli 

 Cygnus, Laeerta, Andromeda, and then through Cepheus, Cassiopeia, and Perseus. The whole 

 was quiet and white. At the next hour there were merely traces in the S. and XW. At J0.17 a 

 white and quiet arch lay over the southern hori/on from ESE. to WXAY., with its crown at an alti- 

 tude of about I.V. with a narrow band from the ESE. through Corona Horealis, Ursa- Major, and 

 Gemini. At 11.15 there was a large patch of luminous haze in the S., and at 12.17 there was a zone 

 (brightness to 1), with its starting points ESE. in Aquila and AVX\V. in Gemini, extending in 

 breadth from Bootes SSW. to Cassiopeia XXK. .Streamers of the same brightness as of the zone 

 ran from Taurus in the XYV. up into Perseus. The horizontal force and declination were more or 

 less disturbed from 7 a. m. to 12 in., the force decreasing and the eastern declination increasing. 



JdiiiKo-i/ 1C, 1SS3, 2.15 ft. m. to 1 a. m. Vague arched bands, which could not with certainty 

 be distinguished from eirro-stratns clouds, were visible at times early in the evening, but there 

 was no definite aurora till 2.15 a. m. (about !) p. in. local), when there was part of a pale arch in the 

 ESE. in Leo, running from below a to ft (brightness to 1). At 3 two broad bauds (brightness 1 

 to 2), nearly straight, slanted up from E. by S. in Leo through Coma Berenices, IJodtes above 

 Boo'tis, into Corona Borealis. At 3.15 it had changed to a narrow arch (brightness 1) from the E! 

 in Leo through the same constellations, fading in the XXK. At 4 there were only evanescent 

 traces over the southern horizon. At 5 a quiet band (brightness to 1) passed from Cygnns 

 through Lyra, Hercules, and Serpens to Bootes. At there were merely traces in the SE. At 7 

 a yellowish band (brightness 1) with a few vibrating streamers ran from Pisces through Aries, 

 Taurus, Orion, and Gemini to Cancer. The haziness nowincreased, and traces only were observed 

 at the next two observations, after which the sky clouded over and the weather became stormy. 

 There was a slight magnetic disturbance at (> a. m. 



hiiutm-ij 17, 1883, 9.10 n. m. to 12.17 p. m. The storm began to break about !J o'clock p. m., 

 local time. At 0.10 a. in. (Washington time) the sky was clear enough to exhibit a white, quiet 

 arch (brightness 1 to 2) from the EXE. to the XXW., through Sagitta, Vulpecula, Laeerta, Cyg- 

 nns, and Andromeda to Triangulum, with faint light, partly masked by the clouds in the southern 

 hori/on. Traces only were visible at 10, though the sky was clear. The weather then became 

 Mornn again, and only traces of the aurora could be observed. Traces of a corona at 11.15 and 

 a lw white and quiet, traces at 12.17. A disturbance of all three elements commenced at 4 a. in. 

 and lasted till 12 m., reaching to maximum at 11 a. in. 



.liiniuiri/ 18, 1883, 12.15 H. HI. to 1.17 p. HJ. At 12.15 there was a waving band of curtains 

 (brightness 1) crossing near the zenith from SE. in Canis Minor to XW. in Hercules, through
