436 EXPEDITION TO POINT HARROW, ALASKA. 



covering nearly all the sky. In about two minutes it began to develop again iu the NW., reaching 

 brightness :!. with bright colors and rapid motion in Cassiopeia, and some reached the zenith, 

 forming an elongated corona of curtains iu very rapid motion in several concentric rows rapidly 

 lading. At 2 a. m. a baud of short streamers ran from a Hydra- through Orion's belt to the clouds 

 in the NW., while there was a broad hazy band just above this, and one long semi-corona the 

 western half of which was a broad, sinuous band, the eastern a fan of streamers, the longest about 

 30, near the zenith, centering about the middle of Camelopardalis and extending from Leo iu the 

 ('.SE. to ( 'assiopeiii in the N W. The streamers wei*o replaced by a hazy band at 2.15 to 2.20, with 

 traces of the corona which were gradually growing more distinct (brightness of all to 1). At 3 

 a. m. there were three hazy arched bands iu the SW., and a narrow zone from the clouds in the 

 ESE. to Cassiopeia NNW. in breadth, from A. Draconis to a Auriga', with a semi-corona E. of the 

 zenith, mostly in Bootes, Canes Venatici and Ursa Major (brightness 1). At 3.15 to 3.20 there 

 were only traces of the zone and corona, while the bauds in the SW. were less distinct (brightness 



to 1). At 4 a. m. there was a wavy broad zone (brightness 1 to 2) brightest on the eastern edge, 

 with the starting points near a Virginis in the ESE. and a Arietis in the NW., with the western 

 edge close to the horizon and the eastern through Corona Borealis, Draco, Cepheus, Cassiopeia 

 and Andromeda, composed of bauds and curtains, with some motion on the eastern edge. At 4.15 

 to -1.20 all was west of the zenith (brightness 1 ) and rapidly fading from above towards the horizon. 

 At 5 to 5.15 a band of curtains and streamers rapidly vibrating and waving (brightness 1 to 2) ran 

 from Andromeda through Lacerta, Cygnus, Lyra and Hercules. At C.20 a band (brightness to 

 1) ran from (iemini to Lynx and Ursa Major. At 7 to 7.20 there were traces only in the SW. At 

 8 to 8.20 the sky was nearly covered by a corona centering in Ursa Major and extending to a band 

 about 15 n to 20 above the horizon. There was no motion near the zenith, but a few bands of 

 streamers in the X. and NW. (brightness '2 to '!). in Auriga and Cassiopeia, were vibrating very 

 rapidly. The last, faint traces were seen in the N\V. at 9.17. The needles were disturbed from 1 

 to S a. m.. the disturbance reaching its maximum at the last hour. 



March 14, 1883, 1.15 a. m. to 9.17 . m. At about .1.15 a. m. there was noticed a faint, narrow, 

 i|iiiel arch in the NE. from ESE. to NNW. just below Cygni through Piootes (close to a), 

 Corona Uorcalis (), <f Lyra- and Cygnus; at 1.20 rising and changing into streamers in the NNW. 

 At 2 a. m. (here was a narrow, indistinct, hazy zone from ESE. in Virgo to NNW. in Andromeda, 

 stretching in breadth from S Ursa; Majoris to <* Persei. This at 2.15 to 2.20 was wholly W. of the 

 zenith, occupying Andromeda, Perseus, Cassiopeia, the upper part of Taurus, Auriga, (iemiui and 

 Lro (brightness to 1). At 3 a. m. there was a broad /one of two main bands, about .">!i apart 

 (brightness 2), starting in the ESE. in Virgo and the NNW. in Aries, and extending from the 

 middle of Camelopardalis near the zenith to about 2 3 below Canis Minoris and the SW., altitude 

 about 25, with a slight waving motion iu the ESE. At 3.15 to 3.20 it was not so bright (bright- 

 ness 1) and the western edge, was unchanged, but the whole had spread 10. .so as to cover nearly 

 the whole sky to within 10 of the horizon iu the NE., and was very sinuous in the N. At 4 a. m. 



1 here was a hazy loop in the N. and NE. (brightness 1) from Aries near <>. through Triangidum, 

 Andromeda. Cepheus () and Draco, bending back near ft Draconis through Hercules (,<), Lyra 

 (/*), Cygnus, and Andromeda. At 4.15 to 4.20 there were pale traces of the loop from Aries up 

 through Cassiopeia' towards the zenith, with a regular arch in the S\V. from KSK. near . Virginis 

 to the moonlight in the NW., with its crown near n- Hydra-, and a belt of three or four bands in 

 the NE.,from N. to E., with its crown near ft Cygni (brightness to 1). At 5 to 5.20 a. m. a quiet 

 baud (brightness to 1) ran from Taurus through Perseus, Andromeda, Cassiopeia. Cepheus, 

 Cygnus, Lyra and Hercules. At to G.20 auroral bands covered ncarh the whole sky. The 

 brightest part, was in the N. and NE. where it had a rapid motion. Round the zenith were only 

 a few taint, (piiet bauds (brightness 1 to 2). There weve extensive traces at 7 to 7.20, and slight 

 traces in the S. at 8.20. Traces of an arch in the SW., from SE. to NW., reaching an altitude of 

 about is ; ; \\itli a taint trace in the NN\Y., could be >;ee.n at 9. 17. There was a magnetic disturb-
