410 EXPEDITION TO POINT KAUKOW, ALASKA. 



anil KSK. At 2 tin- horizon was still obscured and HIM arch was higher and brighter (brightness 

 1 to 2; with its extremities ESE. (observed to be near Itegulus) and NN\V. There was also ;t 

 broad forked hazy band (brightness to 1) from the NNW. end up through Lyra and Cephcus. 

 The arch only remained at 2.1."). At 3 the arch was somewhat irregular (brightness 1) from tho 

 KSI',. to the XNW., passing through Leo. Leo Minor,. Ursa Major, Draco, ;:iid Lyra to Aquila. 

 A< !.15 it \vas brighter (brightness 1 to 2) and an additional band (brightness to 1) through I i.-a 

 Minor connected it into a /one. At -1 a. m. there was a broad hazy /cue (brightness to 1), 

 with its starting points in Hydra ESE. and Aquila NNW., passing through Tamer, Gemini, 

 Auriga. Perseus, Cassiopeia, Andromeda, Pegasus, and Laecrta, and a bflnd (brightness 1 to 2) in 

 the XE. from starting points through Leo, Coma Berenices, Bootes, Corona Borealis, Hercules, and 

 Serpens. This band was in the same place, but the zone was farther E. and narrower and passed 

 through Ursa Major and Ursa Minor. At 5 a. in. a quiet yellowish band (brightness 1) passed from 

 Pisces through Taurus, Orion, and Mouoceros. At C there was a baud (brightness 1 ) waving slightly 

 from W. to E. through Aries, Taurus, Gemini, and Canis Minor. There were faint traces at 7 and 8, 

 also at 10.10 and 12.10. There was a definite aurora at 1 again ; a narrow band (brightness to 1) 

 passing between Gemini and Auriga, through Ursa Minor to Cygntis in the ESE. Faint traces 

 were still visible in the NW. and in Cassiopeia at 2 p. in. There was a disturbance, not very 

 great, with decrease of horizontal force and increase of the other elements at 7 to S a. m., and 

 again much less violent at 1 to 2 p. m. 



December 13, 1882, January 1, 1SS3, 10.15 p. m. to 12.11 p. m. At 10.15 there were faint bands 

 surmounted by very faint streamers in the NE., passing through Gemini, Lynx, and Leo Minor. 

 This had faded at 11.15 to a more hazy streak just above, the NE. horizon, with its extremities 

 bearing X. by W. and E. This disappeared again before the next observation ; was beginning 

 to develop again at 1 a. m. At 2 there were three faint, ill-defined a relies (brightness to 1) in tho 

 NE., from Hercules to Leo, through Corona Boroalis, Bootes, and Coma Berenices, with a faint 

 streamer running up into Draco at the NNW. end. There were three or four additional streamers 

 in the same place at 2.15. At .'> the arches had risen and become a. broad hazy zone (brightness 

 to 1), brightest on the edges, with its starting points in Hydra ESE., and Aquila NNW. The 

 highest point of the eastern edge passed through the top of Canes Venatiei and of the western 

 through the lowest part of Andromeda. This zone lasted two hours, with its starting points 

 Laving the same bearing, of course changing its relations to the constellations as they moved 

 through it, and its band varying slowly in brightness (from to 1 to 1 to 2) and position. At 5 

 there were two bands (brightness Ito 2), one short with streamers on the western end, and a long 

 one below it with streamers in the E., vibrating slowly from W. to E., running through Pegasus, 

 Lacerta, C.vgnns, Lyra, Draco, Corona Borealis, Bootes, and Coma Berenices. At C a quiet band 

 (brightness to 1) ran from Pegasus to Hercules and Bootes. A similar but brighter (brightness 

 1) band at 7 a. m. passed through Canis Minor, Orion, Taurus, Aries, and Pisces. At S a. m. a 

 comparatively narrow zone (brightness 1 to 2) crossed the zenith from Pegasus to Leo M inor, through 



iopeia, Ursa Major, and Ursa Minor. There were besides two bands S. of the zenith from 

 Leo to Andromeda through Cancer, Gemini, Auriga, and Perseus, with several patches of streamers 

 between the bands vibrating rapidly, and a few beams of light from I'rsa Major towards the S. 

 (brightness 1 to 2). At 9.17 there was a broad band (brightness 1 to 2) from the HE. to XW., with a 

 smaller band meeting it at its SE., and in Canis Minor in the W., about 5 apart in the middle, 

 with white and quiet streamers above and from the smaller band extending towards the zenith. 

 Traces of aurora continued visible till 12.17p.m. The magnetic; needles were remarkably quiet 

 up to i a. m., when there was a slight disturbance, lasting over two observations a decrease of all 

 three elements. They again became quiet at S a. m., the horizontal force suddenly fell too low to 

 read, and gradually recovering itself during the next two observations, while the other elements 

 were almost undisturbed, both rising slightly. 



.tn,n"i>-y I and 2, lss;>. 10 p. M. to 7 a. . At 10 p. in. there was a patch of aurora in the NE.in 

 Cancer and Leo Minor, forming an irregular arch, with ill-defined streamers. This had wholly 

 disappeared in ten minutes. At 11.15 there was an example of a new form of aurora, two arches 

 arranged longitudinally, one narrow and rather irregular from Bootes through Coma Berenices, 

 Leu. and Cancer to Canis Minor, reaching an altitude of about 15 in the NE.. and the second
