398 EXPEDITION TO POINT HARROW, ALASKA. 



Auriga, Cassiopeia, and Camelopardalis to Leo. At 7 the aurora bad tbe same position and char- 

 act IT as at 5. At S a. in. an arch (brightness 1) extended from P.odtes through Draco and Cygnus 

 to Pegasus. At !>.17 there were two white ami quiet bands (brightness to 1) started together 

 from Bootes in the SE. and met in Taurus in the W., one running about 3(P above the southern 

 horizon and the other crossing the zenith. At 10.10 the lower band had disappeared, but the one 

 across the zenith remained unchanged, while another band appeared extending from the Pleiades 

 to Perseus, Cassiopeia, and Ccpheus to near Hercules. At 11.17 there was a white, quiet band 

 (brightness to 1) from the SK. to NW. through the Pleiades and Coma Berenices and close to 

 Ursa Major. Only faint traces were visible at 12.17 p. m., and these had wholly disappeared at 

 1 p. m. The magnetic needles were unusually quiet, only showing signs of disturbance at 9 a. m 

 and 12 and 1 p. m. 



mbc'f 3 and 4, 1882, 9.15 p. m. to 1.15 p. m. At 9.15 p. in. the aurora commenced as pale, 

 lilies of light in NE. through Gemini and Taurus, with faint streamers in Lynx. At 10.15 there 

 was a quiet arched baud (brightness to 1) through Taurus, Gemini. Leo Minor, and Coma 

 Berenices, with streamers iu Leo Minor and Ursa Major. It was brightest in Leo Minor and very 

 faint in Gemini. For several hours the bearing of the aurora was unchanged, but it appeared in 

 different constellations as they rose. At 11.15 there were no .streamers. At 12.15 the arch passed 

 through Orion, Geuiiui. Leo, Leo Minor, Coma Berenices, with streamers iu Coma and Ursa Major 

 (brightness 1). At 1 a. in. there were merely traces along the eastern sky from the K. to ESE., 

 but these soon developed into an arch of pale streamers (brightness to 1) from Orion's belt in the, 

 ESE. through Canis Minor, Cancer, and Leo, ending close to Boo'tis, here sending off long 

 streamers towards the zenith. From 2 to 2.15 a. m. there were two principal arched bauds, the 

 upper sending off short streamers, starting from a point in Monoceros close to the horizon in the 

 ESE. and meeting at a point in Serpeus similarly close to the horizon in the NNW. (brightness 1 

 to 2), through Gemini, Lynx, Ursa, Major, and Canes Venatici, rising slowly and sending off pale 

 narrow bands from the northern end, which gradually stretched up towards the zenith. At 3 a. in. 

 streaks and curved bands, varying in brightness from 1 to 3, covered most of the sky. The start- 

 ing points were in Serpeus in the NNW. and Mouoceros in the ESE. It was brightest in Cygmis 

 and Pegasus, when it formed an irregular ellipse, with its longest diameter N. and S., with consid- 

 erable whirling motion, and across through Canis Minor, Leo, Leo Minor, Canes Venatici, Ursa 

 Major, and Hercules, where it was a baud of streamers vibrating rapidly from N. to S. The 

 brightest part was slightly tinged with greenish-yellow and rose. At 3.10 it was broken and 

 paler and the eastern band had split into three, and was fading at 3.15, still brightest in the NE. 

 At 4 a. m. there was a faint, low, quiet, and regular arch in the SW. from the NW. to S., reach- 

 ing an altitude of about 15. and bright, curling, wreathing bands (2 to 3), which in 10 minutes 

 spread over most of the sky, coming up from a point iu Serpeus near the horizon in the NW., one 

 main branch crossing the zenith and spreading out to Ursa Major, ami Gemini; another through 

 Pegasus. There were also bright disconnected whorls in the NIC. The main band moved slowly 

 with a waving motion to the west. At 4.15 it was more spread out and not so bright. At 5 there 

 was a bright corona, yellowish in color (brightness 3 to 4), centering a little south of the zenith. 

 The northern streamers of the corona vibrated rapidly in every direction. The corona had disap- 

 peared at 5.20, leaving the sky covered with faint luminous bands resembling stratus clouds. 

 There was a magnetic disturbance. At (> a. m. there were two motionless arches (brightness 1), 

 one through Taurus and Orion to Canis Minor and the other from Sagitta to Bootes. At 7 there 

 were only faint traces of bands. At >S a band (brightness to 1) extended from Cygnus through 

 Draco, Ursa Minor, Ursa Major, and Cassiopeia to Leo Minor and Gemini. At !t there were 

 merely a few traces over the southern horizon. No aurora was seen at 10, but at 11 a. m. there 

 were two yellowish-green arches (brightness 1), one through Orion and Canis Minor to Leo, and 

 the second from Taurus across the zenith to Coma Berenices. At 12 m. there were only traces of 

 aurora, and at 1.15 p.m. the last of the aurora appeared as a narrow band (brightness 2) extending 

 from Cassiopeia through Perseus to Gemini. The needles were considerably agitated at 3 and 4 

 a. m.. much disturbed at 5 a. m.., the horizontal force being too unall to register, and again at 12 in. 

 The other two elements were but little affected.
