EXPEDITION TO POINT BARROW, ALASKA. 409 



and Hydra. There were a few traces ill the NW. and E. at 9.15. The 10.15 observation showed 

 a luminous patch (brightness to 1) in Taurus in the NW. horizon, and extending through Auriga, 

 and another similar patch in Cygnus. At 11.10 a narrow white band (brightness 1) extended 

 from the SB. to the W., with its crown at an altitude of about 20, its western end being somewhat 

 broader. A white, quiet baud also extended from the horizon SW. to Polaiis. At 12.17 p. in. 

 there was an aurora reaching the horizon in the NE. and W. (brightness 1), white and quiet. At 

 1 p. in. there was a zone of the usual type, with its starting points NNW. and SSE., starting from 

 Lacerta and reaching to Leo Minor. This was reduced to traces at 1.12, and faint traces were, still 

 discernible at 2.15. A ritagnetic disturbance began at about 2 a. in. and reached its maximum at 

 8 a. m., the horizontal force falling too low to Vje read, and the eastern declination increasing over 

 a degree. The disturbance was large again at 1 p. in. 



December 19 and 30, 1882, 10.15 p.m. to 3 p. m. At 10.15 p. m. there was a low arch (brightness 

 1), with its extremities bearing E. by S. and N. by W., passing through Orion, Gemini, Lynx, and 

 Leo Minor, and faint recurved streamers in Coma Berenices and Canes Venatici. At 11.15 the 

 arch was irregular and waving (brightness 2), and passed through Orion, Gemini, Leo Minor, Lynx, 

 Coma Berenices, and Bootes. At 12.12 a. ui. there was an irregular and waving arch, very low in 

 theXE,, through Cauis Minor, Leo, Coma Berenices, and Bootes, with a few faint streamers in Bootes 

 (brightness 1). The arch had risen at 1 into a broad zone, with its starting points in Hercules in 

 theXXW. and Monoceros in the ESE. The western band (brightness 1 ) crossed through Cassiopeia, 

 but failed before reaching Monoceros. The next baud only readied I'rsa Major, while the eastern, 

 which was the brightest (brightness 2) and yellowish in color, passed through Corona Borealis, 

 Bootes, Canes Venatici, Leo Minor, and Cancer, and there were also below this two or three paler 

 partial bands. At 1.15 the whole had faded to traces except the band in the E.. which, now ran 

 through Leo. At 2 a. ui. there was an arched band in the same place (brightness 1) and a streamer 

 from the XXW., and reaching into Lyra. Tin's streamer was gone at 2.15, the band was paler, 

 and tliere was a streamer in the, ESE. Erom 2 to 3.15 there was a broad /one (brightness to 1) 

 of hazy bands, broad and somewhat shifting. The starting points were in Hercules in the NN W., 

 and a line in Monoceros and Hydra from the SE. to the ESE., and the sky was covered by the 

 zone between Leo iu the NK. and the lower part of Pegasus in the SW., except between the zenith 

 and 1'rsa Major. At 4 the zone had nearly all faded except the eastern baud and another 

 about 20"- broad through Cassiopeia. This had shifted westward into Perseus and Andromeda at 

 4.15. and was lading rapidly. At there was a motionless band (brightness 2) in the SW. through. 

 Canis Minor, Cancer, Gemini, Orion, Taurus, and Pisces. At i> a. m. an extensive zone (brightness 

 1 to 2) covered the, sky. The starting points were in Pegasus WXW. and Leo ESE., the edges 

 running through Aries, Gemini, Coma Berenices, Bootes, Corona Borealis, Lynx, Cyguus, and La- 

 ecrta. There, was a slow waving motion, and some of the bands were broken into streamers. At 

 7 there was a faint band (brightness to 1) through Delphinus, Hercules, and Bootes. At S a baud 

 (brightness 2 to 3) with streamers hi rapid motion, colors changing from yellow to green and red, 

 ran through Triangulum, Aries, Taurus, Perseus. Auriga, Gemini, and Leo. At 0.10 there was a 

 bright patch in the E. and XE. at an altitude of about 20, with long faint streamers extending 

 to Polaris. It was white and quiet (brightness 2). At 10 there were a few faint, traces, but no 

 more was seen till 1 p. in., when the aurora revived as a sigmoid braid (brightness to 1) extend- 

 ing from Leo Minor in the SW. to Bootes in the S. A twisted band ran through Ursa Major from 

 Gemini to Hercules, while a crown of the same brightness, fading very rapidly, was found in I'rsa 

 Minor. At 1! tliere was a broad band (brightness to 1) in the NE., through Cygnus, Perseus, 

 Liu-crta, and Auriga, and faint traces of coronal streamers and of streamers in tlie SW. The last 

 faint traces were still visible in the XE. at 3 p. m. The horizontal force instrument was agitated 

 between 2 and 4 a. in., and there was considerable disturbance, chiefly affecting the horizontal 

 fo:ve. from S a. in. to 3 p. in. 



IhTiitiln i- .'10 mill 31, 1882, 10.15 p. m. to 2 y>. . The aurora began at 10.15, with a tiush in the 



. continuing but little changed at 11.15. At 12.15 n. in. it had developed into a definite though 



pale band, through Gemini, Leo Minor, and Canes Venatici. Froml to 1.15 the eastern horizon was 



much obscured by haze, and there was a regular but rather narrow arch in the NE.. with its 



crown Apparently in Coma Berenices, at an altitude of about 25, with its extremities about N.
