EXPEDITION TO POINT I5AKEOW, ALASKA. 393 



17, 1882, 12.15 . m. to 12.30 ji. i. At 12.15 a. in. faint streamers were observed in 

 the X., partially obscuied by clouds. At I a. in. there was merely a pain glow all around the 

 horizOB, bnt ten minutes after there waa rather a broad arclicd streak (brightness 1) naming up 

 from dose to Arcturiis in tlic N. near the liori/.on, through Canes Venatici and Ursa -Major, ending 

 close ub.ive Castor and Pollux. At 1.17 (here, was a twisted baud from the same point in the N. 

 up to Ursa Major. From 2 to 11.17 there was a pale glow all around the horizon, with occasional 

 faint streamers close to the horizon in the SE. At 3 a, m. there was a pale band (brightness 1), 

 divided lengthwise, so tin- ends overlapped at the zenith, crossed the zenith from Auriga high iu 

 the KSE., through Cassiopeia to Draco, reaching down towards Bootes at .'5.10 and fading at the E. 

 end. There were also traces in the E. iu Orion, Cancer, and Leo Minor, developing into a palo 

 arch of streamers at 3.17, while the rest of the aurora faded. At i a. m. there were pale bands 

 and streamers in the NE,, developing at -i.17 into a twisted vertical band in the NE. (brightness 

 1), occupying Leo Minor and the whole of Ursa Major, and spreading pale and hazy toward tho 

 zenith. The horizontal force fell suddenly with the development of this baud. There was also a 

 pale band in Lyra in the NW. At 5 a. in. there was a pale arch from Hercules to Serpens, and 

 three or four bunches of streamers in Cygnus, Lyra, and Corona Borcalis (brightness tol), and no 

 motion. At G a. m. there was a quiet band from Pegasus, through Triangulum to Taurus, with no 

 motion. This was almost hidden by haze at G.20. After this the sky became covered with 

 clouds, only clearing at intervals. Traces of aurora were observed at 9.17 aud 10.17, at the latter 

 observation giving indication of an extensive aurora behind the clouds. Traces were again vis- 

 ible at 11.20 through the clouds. At 12.15 p. in. the sky cleared, and was observed to be encir- 

 cled by a broad band of white, quiet light. In a few minutes the sky from the NE. to SE. points 

 became colored a bright rosy red, the color fading away towards the zenith. About the same time 

 a large white curtain formed across the rest of the sky, remaining nearly motionless for several 

 minutes, and then gradually disappeared, while the red color spread farther S., and bright rays 

 shot up towards the zenith, forming a perfect coroua, which continued about forty minutes. The 

 streamers of the coroua were white and motionless. When the red color first appeared the light 

 was striated with the rays parallel to the magnetic meridian, and several stars were visible showing 

 through the colored portion with undiminished brilliancy. At 1 a. m. traces of aurora were 

 observed in Bootes. The magnetic were almost undisturbed up to C a. m., when a violent disturb- 

 ance commenced, still going on at daylight. 



\'<>remlicr 18, 1882, 7 a. m. to 12.17 p. m. The weather was stormy during most of the night, 

 but the clouds thinned away from 7 a. in. to 12.30 p. m., permitting portions of the aurora to bo 

 seen. At 7 a. m., a band of streamers vibrating up and down, and also from E. to W. (brightness 

 1 to 2) was seen stretching from Orion through Aries to Pegasus, while another baud without 

 streamers ran from Orion through Perseus and Cassiopeia to Cygnus, moving slowly towards the 

 SW. At 8 there was a faint arch (brightness to 1) from Orion to Pegasus. Traces were seeu 

 through the clouds at !>.17 and at 10.17 in the E. aud SE. At 12.17 there was a quiet white nebu- 

 lous band (brightness o to 1 > from the. SE. to the N., reachiug an altitude of about 40 above the 

 horizon, in tho S. 



\orfinl,* -i- is ,i,t/l 10, 1882, 0.15 j>. m. to 0.17 . m. During most of the night the sky was cov- 

 ered by thin hazy stratus clouds, through occasional breaks of which traces of aurora were observed 

 from time to time, beginning as early as 0.1.3 p. m. on the 18th. At 10.15 the sky was clear enough 

 to display a w.iviii:, ham! (brightness 1) from Coma Berenices in the NNW. through Canes Veua- 

 tici, Ursa Major, I'rsa .Minor. Cassiopeia to Pegasus in the ESE. It was brightest in Ursa Major, 

 where it was broken into streamers. At 11.15 an arch was observed through the haze, very dim 

 and wide, in places, broken into three parallel bands, with its extremities bearing NW. and SE. 

 The next hour it was cloudy, but the clouds appeared luminous here and there. At 1 a. in. on the 

 10th there were traces of aurora through the clouds in the N., and at .'5 a. in. traces of bands 

 crossing the zenith from X W. to SE. were, seen through the clouds. At 4 similar traces were seeu in 

 the NE., and at 8 and 0.17 a. in. in the S. and W., and at the last hour also at the zenith. There 

 was considerable, magnetic disturbance during the whole night. 



Noccinlicr 1!) a nit 20, 8 p. m. to 11.17 a. m. Just before the 8 p. m. observation, the sky being 

 clear and the, twilight, still bright, pale streaks of aurora were observed in the N., high up in the
