392 EXPEDITION TO POINT BARROW, ALASKA. 



close to tlio liorizon in the NN W. This /.one was much twisted in the N. (brightness 2), showing 

 a faint rose tinge in the N. and >SE. At 2 a. in. it was in the form of two bands, one from Canes 

 Venatici through I'rsa Minor to Andromeda, the other across the /eiiitli from Ursa Major to Taurus 

 (brightness ;?). Uetween Iliis observation and the next the aurora reached its maximum, being a 

 great display of the usual type, bands, curtains and streamers covering the whole sky, with much 

 play of colors, and vibration, lading rapidly. At 3 a. m. there were three bands with streamers, 

 two from Aquila in the NW.. through Cygnus and Hercules, and one arch from Pegasus to Aries 

 (brightness 1 to 2\ displaying yellow, green and pale blue colors, and vibrating rapidly. Between 

 this observation and the next the aurora was again brilliant, but at t a. in. had faded to a quiet 

 baud [brightness to 1), round the horizon, and at 5 there were two similar bands from NW. to 

 SE. At 0.17 there was a faint illumination in the southern horizon, and quiet curtains in the N. 

 At 7 a. in. there was a faint band in the SW., from Pegasus through Taurus to Gemini, with pale 

 streamers moving slightly at the western end, and also several patches in Lacerta, Cassiopeia, and 

 Ccpheus. At 8.15 there were a few pale, white, quiet streamers between the N. and SE., and no 

 aurora was seen at the next observation ; but at 10.15 there was a faint arch from the SE. to SW., 

 with an altitude of about 20, with the lower edge well defined and showing a dark segment. At 

 11.15 there were faint streamers in the E., passing from the horizon through Canes Venatici, Coma 

 Berenices, Bootes, and Lyra, and converging to a point just above and ,i Ursa- Majoris. At 

 12.15 then- were very pale streaks in Ursa Major, nearly reaching the zenith, and traces of aurora 

 in the NW. obscured by clouds. The magnetic disturbance of yesterday continued pretty violent 

 up to about a. in., since which time the instruments have been comparatively quiet. 



Xoventber 16, 1882, 12.15 p. m. to 11.20 a. m. The aurora did not begin till some time after 

 dark, first appearing as a faint streak of light in Leo Minor. At 1 a. m. there was a pale glow 

 all around the horizon, brightest in the N., when at 3.17 three vertical streaks had developed, the 

 largest running from near Arcturtis to Draco, very pale (0 to 1). At 2 a. in. there was a narrow 

 hazy band (brightness to 1) across zenith from a point in the lower part of Taurus in the ESE. 

 through Perseus, Triaugulum, and Cassiopeia to Draco, brightest close to the SE. part, where it 

 reached brightness 1 at 2.17, the crown having drifted westward to Cyguus and the band broad- 

 ened a little, running down closer to the NNW. horizon in Corona Borealis. At 3 a. ID. there was 

 a broad, pale zone, much broken (brightness to 1) from the same points in the NNW. to SE., 

 from the SW. horizon to an altitude of about 20, beginning to brighten and develop streamers at 

 3.10. At 3.17 it was rising in the form of an arch of streamers, approaching the curtain form, till 

 it reached the square of Pegasus, Cygnus, and Lyra, where it began to fade and then develop into 

 a paler zone of sinuous streaks. There was some vibration from E. to W. and a faint green tinge 

 on the upper edge, shading through yellow to pale rose. There was a similar but smaller arch in 

 the E. in Gemini and Cancer, and another in Leo. At 4 a. m. there was a broad zone of the usual 

 type (brightness 2 to 3) from a point in Monoceros close to the ESE. horizon to a point in Serpeus 

 in NNW. occupying Orion, Taurus, Auriga, Perseus. Andromeda, Cassiopeia, Pegasus, Cygnus, 

 and Lyra. The eastern edge was the brightest and much twisted. The aurora in the E. was essen- 

 tially unchanged. There were additional streamers from the tail of Ursa Major to the zenith ut 

 4.10. At J. 17 the bands of the zone were separating and growing paler except the westernmost 

 (brightness 3). At 5 a. m. there was a band with motionless streamers from Canis Minor through 

 Orion to Pisces about 5 to 8 above the horizon, and a paler band shaped like a horseshoe from 

 Orion to Leo. At G a. m. a bright band crossed the zenith from Lyra through Ursa Minor to 

 Gemini, moving slowly to the south. At 7 there were two faint arched bands around the hori- 

 zon. At 8 there was a corona, with its center a little W. of the zenith, covering almost the whole 

 sky. From the center beams extended to bands and streamers. It was nearly gone at 8.'_'0 a. in. 

 (brightness 1 to 2). At 9.17 there \. as a broad white quiet band (brightness 1) from Andromeda 

 through Cassiopeia, Camelopardalis, and Ursa Minor, ending in Bootes, with also a faint glow 

 on the southern horizon. The band had disappeared at 10.17, and the glow had developed into 

 an arch with its corona at an altitude of about 20, with short streamers from the arch. There 

 were also streamers 15 ' long in the NK., E. and 8. about 20 above the horizon. At 11.20 there 

 were a few faint quiet streamers in the NE. The needles were but slightly disturbed; most so 

 about I a. in.
