EXPEDITION TO POINT BARROW, ALASKA. 433 



quiet baud from Pegasus through (Oriou, Gemini, Cancer, Leo) 6, Cygnus, Aquila, aud Serpens 

 (brightness to 1). At 9.17 there was a diliused arch from the SE. to NN\V., with its crown at 

 an altitude of about 20, with faint streamers in the NNW. At 10.17 there was a faint trace of 

 an arch across the zenith from SE. to NW. Only slight magnetic disturbance was noticed. 



M/n-ch 5, 1883, 12.15 . MI. to 8.20 . MJ. At 12.15 (about 7 a. in. local) there was a faint arch in 

 the NE., with its extremities bearing ESE. and NE., and the crown at an altitude of about 45, 

 with streamers in the NW. At 1 a. m. a broad twisted band (brightness 1 to 2), shifting and waving, 

 crossed from ESE. in Leo to NNW. in Pegasus through Leo Minor, Ursa Major, Lynx, Ursa Minor, 

 Cassiopeia, Cepheus, aud Lacerta. It had drifted west to Auriga and Gemini at 1.15 to 1.20, and 

 was brighter (brightness 2), and gradually spread towards the E., beginning to gyrate in the SE. 

 in indistinct curtains. At '2 a. m. there was a rather narrow zone, with some of the bands approach- 

 ing the curtain form from, nearly the same starting points, broadest from C Ursie Majoris nearly 

 to a Auriga>, with the bright portion mostly NE. of the zenith, and waving somewhat. It was 

 broader at 2.15 to 2.20, and not so bright (brightness 1), and the bands were closer together, with 

 less motion. At 3 there was a very broad zone (brightness 1 to 2) from nearly the same starting 

 points, in width from a Lyric and Bootis to Canis Minoris and a Tauri, brightest on the eastern 

 edge and in the part west of the zenith, with a slight waving motion. At 3.15 to 3.20 the edges 

 had faded and all was slowly fading except the extreme NE. bend. From 4 to 4.20 there were 

 remains of the aurora (brightness to 1) in essentially the same position, which had nearly all 

 faded, except the western band, at 4.20. At 5 to 5.20 a quiet band (brightness 2) ran through 

 Taurus, Gemini, Oriou, Cancer, Leo, Coma Berenices, aud Bootes. At to 6.20 a corona (bright- 

 ness 1) covered nearly the whole sky, centering in Ursa Major, and in rapid motion. Faint traces 

 of this still remained at 7 to 7.20, and traces were again seen in the NW. aud SW. at 8 to 8.20. 

 After this the weather became cloudy. The magnets were comparatively quiet all night. 



March 0, 18s:>. 3 a. >u. to 9.17 a. m. The aurora may have begun a little earlier, as there was a 

 bank of hazy stratus clouds in the NE., but the first that could be recorded with certainty was at 

 3 to 3.20, when there were ill-delined luminous patches in the E., partly obscured by clouds, fol- 

 lowed by exceedingly faint vertical streaks, first one aud then three, streaming up from the SE. 

 towards the. zenith with a better defined streamer close to the horizon in the NNW. at .'!.20. At 

 about .'i.40 these had developed into a baud (brightness 1) from the clouds in the ESE., across the 

 zenith to a Andromeda? in the NNW., which broadened into a zone, and at 4 to 4.15 was reduced 

 to hazy traces about 30 in width near the zenith. These gradually became brighter in the SE., 

 streaming up through Leo (/5) to the zenith. At 5 to 5.20 only traces were observed, a little south 

 of the zenith. At the next observation none was seen, but at 7 to 7.20 a quiet band (brightness 

 to 1), from Taurus through Orion, Gemini, and Leo. At 8 to 8.20 a. m. there were traces in NW. 

 and SAY. At 9.17 there was an arch from NW. to SE., with -its crown about 20 above the 

 southern horizon and traces in the NNW. No more was seen after this, though the sky was clear. 

 There was a slight magnetic disturbance, beginning at 9 a m. 



Nnrcli 7, 1883, 12.15 a. m. to 10.17 . m. At 12.15 there were faint si reamers in the 1C., which 

 at 1 a. in. had developed into a twisted baud of streamers (brightness 1), from ESE. in Hydra, 

 through I, eo. Lynx, Camelopardalis, and Cassiopeia, swinging round into Perseus somewhat in the 

 form of ;i corona, with slight motion. The baud was in the same position, with a well-defined 

 semi-corona SW. of the. zenith, reaching into Auriga and Gemini, with the band extending down 

 into Andromeda NNW., the whole soon fading. At 2 to 2.20 there was an arch of shifting 

 streamers (brightness to 1) in the SW., much obscured by haze aud clouds, especially near the 

 horizon, reaching an altitude of about 30, aud passing through Leo, Cancer, Gemini, and Taurus. 

 At 3 a. m. there was a somewhat irregular corona, connected with the horizon by narrow streaks 

 ESE. and NXW., aud made of curtains (brightness 1 to 2) running round through Leo Minor, 

 Lynx, Gemini, Taurus, Aries, Andromeda, Cassiopeia, Cepheus, Draco, and I'rsa Major, surround- 

 ing hazy curdled streaks (brightness to 1) about the zenith, with slight motion. At 3.15 to 

 ."..20 only (lie western portion remained, forming a sort of zone, combined with a semi-corona, and 

 slowly shifting. At I there, was merely an ill-defined arch of streamers in the SW., which at 4.15 

 had become llin-e or lour shifting bands of curtains, nickering from the extremities towards the 

 center (brightness 2 to .'!), tinged slightly with the usual colors. This soon rose towards the
