EXPEDITION TO POINT BARROW, ALASKA. 



and continued unchanged at G.15 to 0.20. At 7.15 to 7.20 then- were only left traces of long 

 streamers in the S., all running to Ursa Major. The magnetic disturbance .still continued at 

 9 p. in. 



April 4, ISS;;, ].45. m. to 7.20 a. m. At 1.45 the daylight was still bright, and an exceedingly 

 faint band appeared in the ESE. extending towards the NW. about 10 west of the zenith. None 

 was to be seen at 2 a. in., but at 2.15 to 2.20 there were traces in the ESE. gradually developing into 

 very pale shifting curtains across the S\V. beginning to wave rathei 1 rapidly in the S. At '' a. in. 

 there was a broad shifting hazy zone across the zenith from ESE. in Virgo to the NW. with its 

 western edge in Hydra, Canis Minor and Orion, and its eastern in Bootes, Ursa Major, Draco, 

 Cepheu?, Cassiopeia and Perseus (brightness to 1). This had faded to traces at 3.15 to 3.20, 

 except some brighter bands in the E. through Serpens, Aquila, and the lower part of Cygmis, 

 quickly rising to nr Lyras and instantly fading. At 4 a. m. traces of the '/.one were to be seen and a 

 patch of ill-defined curtains (brightness 1 to 2) in. Cygnus and Andromeda, NNE., with a bright 

 long streamer or two. All had faded to traces at 4.15 to 4.20, but curtains were beginning to de- 

 velop in the NNW. At 5.15 to 5.20 there was a baud of slowly vibrating streamers (brightness 1) 

 from Taurus through Auriga, Perseus, Cassiopeia and Cepheus. At G.15 to G.20 there was a quiet 

 baud (brightness to 1) through Gemini, Lynx, Ursa Major and Bootes. Traces alone remained 

 at 7.15 to 7.20. The magnetic disturbance continued all night. 



April , 1883, 4.15 a. m. to The sky was covered by clouds all night, but at 4.15 to 



4.20. \vlienthe magnets were very much disturbed, auroral light appeared in the NE. showing 

 strongly through the clouds, and quickly rose as a baud across the zenith and disappeared it, the 

 W., while fresh patches of light developed in the E. The magnetic disturbance continued all night. 



April 7, 1883, 4.15 a. m. to A very faint evanescent streak was observed curving up 



through Aquila close to the horizon bearing E. by S. ; clouds interfered later in the night. The 

 magnetic needles were uncommonly quiet, though there was a low horizontal force. 



April 8, LS.S3, .'!.45 a. m. to G.20 a. m. Sinuous traces appeared in the ESE. at 3.45 and had 

 developed at 4 a. ni. into definite pale sinuous bands in the E. coming up through Aquila into 

 Lyra and Cygnus. At 4.15 to 4.20 these had developed into a broad belt of waving sinuous bands 

 (brightness 1 to 2) in slow motion extending from Aquila near a through Lyra, Cygnus, Cassiopeia 

 and Perseus, and gradually broadening and shifting and rising. These had faded to quiet bands 

 (brightness to 1) at 5 to 5.20, crossing high in the sky through Auriga, Gemini, Lynx. Came- 

 lopardalis, Ursa Major, Ursa' Minor, Draco, Bootes and Hercules. Traces were still visible in the 

 S. at G to G.20. 



April 9, 1SS3, 3.45 a. m. to G.20 a. m. A very faint baud crossed the zenith through Bootes 

 and Ursa Major, running SE. and XW. at 3.45 a. m. This had become sinuous and shifting at 4 

 a. in. and extended on through Cepheus and Perseus, with shifting sinuous bands on either side, 

 iiie in Draco and the other in Auriga and Gemini. All had faded to traces at 4.15 to 4.20. At 5 

 to 5.20 a faint luminous band ran from Serpens through Bootes to Coma Berenices (brightness to 

 1). Traces only were to be seen at G to G.20. There was magnetic disturbance chiefly affecting 

 the horizontal force at about 8 a. in. 



April 13, 3.45 a. m. to 5.20 a. m. At 3.45 the twilight was quite bright and the stars obscured 

 by haze. A faint arched yellow baud lay in the SW. from near the horizon ESE. to the light in the 

 N YV. reaching an altitude of about 40. At 4 a. in. there were barely perceptible traces in the S W., 

 but at 4.15, as indicated by the agitation of the needles, there was an extensive aurora in rapid 

 waving and vibrating motion in the form of a zone about 30 or 40 degrees broad, and composed 

 mostly of curtains and coronal streamers, crossing the zenith from ESE. to NW. The usual color 

 appeared with the yellow very prominent (brightness 2 to 3) and the whole moved quickly toward 

 tin- magnetic N. The stars were only faintly visible. When the north magnetic edge had reached 

 a Lyra' the rest had faded, and all was soon reduced to sinuous traces occasionally brightening up 

 again, but all was nearly faded at 4.20. These developed into a narrow band again at 4.45, but at 

 5 to 5.20 then- was only a pale, quiet baud (brightness to 1) through Perseus, Andromeda, Cas- 

 siopeia, Lacei ta and Cygnus. The needles continued more or less agitated till 2 p. in., being con- 

 siderably disturbed at ! p. m.
