428 EXPEDITION TO POINT BAKKOW, ALASKA. 



of twisted streaks, angular curtains and streamers, with some motion (brightness mostly 1, reach- 

 ing '2 in some places). Two bands were well delined, one on the eastern edge from Leo through 

 Leo Minor, I" rsa Major, Draco, Ursa Minor and Draco again to Lyra, and the other oil the west- 

 ern edge through Cancer. < 'anis Minor. Ucniini, 'i Tauri, I'erseus. and Andromeda. The zone had 

 moved toward the W. at 1.1. ~> and was not so well defined, while a band of indistinct shifting cur- 

 tains ran from Orion's belt to Canis Minor (a) and curving buck to fi Tauri. At 2 a. m. a broad 

 band ran from the ESE. in Hydra through Leo, Leo Minor, Lynx and I'rsa Major, Camclopard- 

 alis, I'rsa Minor. Cassiopeia, and Andromeda to NW. in Pegasus. This was constantly changing 

 its shape with rapid, twisting, whirling, and waving motion, shifting also from E. to W. and back 

 again. It was tinged with shifting colors, pale green and rose (brightness 2 to 3). There were 

 also quieter bands from the same starting points lying towards the SW., the lowest passing through 

 the Hyades. The main aurora had faded to traces at 2.15, leaving large, patches of luminous haze, 

 while a narrow band (brightness 2) ran from Pegasus through Cygnns, Lyra <. j, and Bootes 

 At 3 a. m. a narrow, twisted, shifting band, composed partly of streamers, passed close to the ze- 

 nith from E.. low in Uoiitt-.-, through the tail of Ursa Major, Draco, Ursa Minor, Cepheus, Cassi- 

 opeia, and Andromeda to the NW. in Pegasus (brightness 1 to 2), with two pale arched bands in 

 the SW., the lower from Pegasus, through Aries, Taurus (a), the head of Orion and Canis Minor 

 (), ending in the moonlight SIC. It was much faded and broken at 3.1<i. At I a. in. there was 

 a similar band, tinged with green and rose, starting high in the NW. in Perseus, passing 

 through Auriga (6) Lynx, Leo Minor, and Coma Berenices, ending in the ESE., shifting and wav- 

 ing. 4.15 found it broken and shifting, passing throng!) () Auriga-, with some ill-de-lined patches 

 and bands in the SW. Traces only were observed in the SE. at f>, and no more was seen till 8.15, 

 when a rapidly waving band ran from Taurus through Auriga, Camelopardalis, and Ursa Minor 

 to Bootes i brightness 1 to 2). The needles were considerably disturbed from 11 p. m. to 10 a. m., 

 the greatest disturbance being at 2 a. in. 



February 23 and 24, ls,S3, 11.55 p. m. to 1 1.17 a. m. When the aurora was first noticed, shortly 

 before midnight, Washington time (0.40 local), it was in the form of two faint, slightly arched 

 bands in the >"E. about ofP above, the horizon. At 12.15 it was an arch of tine streamers, with its 

 extremities bearing NW. by N. and ESE., and its altitude about 3(1 (brightness 1). This band 

 was essentially unchanged in character and position at 1 a. m., with an additional hazy band 

 (brightness 1), from nearly the same starting points, passing through Leo, Leo Minor, I'rsa Major, 

 Draco. I 'rsa Minor, Cepheus, and Cyginis. This had disappeared at 1.15 to 1.20, leaving the first 

 band, which had become more compact and brighter (brightness 1 to 2). At 2 a. m. there was a 

 regular arch (brightness 1) from the ESE. in Virgo to the NNW. near fi Cygni, through Coma 

 Berenices'Bootes, Corona Borealis, Hercules, and Lyra (). This was fading rapidly at 2.15 to 

 2.20. There was no aurora al ''> or f, though faint and fugitive traces were noticed between the, 

 two hours. At 4.15 there were faint traces in E. and a band (brightness to 1) from N W. in IV 

 gasns through Andromeda, Perseus, and Auriga. From 5 to 5.20 a. m. there was a yellowish zone 

 (brightness 1 to 2) with the bands in rapid waving motion from Orion to Bootes and Serpens 

 through Gemini, Lynx. I" rsa Major, and Canes Venatici. From fi to 0.20 there was a band of 

 streamers (brightness to 1) vibrating rapidly from W. to E., running through Perseus, Cassiopeia, 

 Cephens. Cygnus, Lyra, and Hercules. At 7.20 and S.20 traces only were observed, and also at 

 !.17. when they were in the SE., white and shifting. At 10.17 there were curtains from NNW. to 

 ESE., with streamers in Leo Minor. All were white, with occasional tinges of green and yellow, 

 and changing form and position very rapidly. At 11.17 there were faint traces near the zenith, 

 with faint streamers in the W. The needles were jnore or less agitated all night, the disturbance 

 being extreme at S a. in., 9 to 0.30 a. in., and 2 to 2.40 p. in. 



I'l-hrinn-i/ L'5. ISS3. 12.15 n. m. in 9.17 n. . Tlie aurora began as a faint bunch of streamers 

 in the SE. at 12.15, and at, 1 a. m. had developed into four bands of ill-defined curtains, forming 

 a sort of zone in the SW.. with its starting points NW. in Pisces and ESE. in Hydra, the upper- 

 most passing through Triangulum, Perseus, Auriga, (lemini, Cancer, and Leo. the lowest through 

 Canis Minor, Orion, and Taurus, with slight waving motion (brightness I). It had the same general 

 character at 1.15 to 1.20, but was rather lower. Erom 2 to 2.15 it was nearly in the same position,
