were Mill traces in the N\V. This last ar.rora was accompanied with a violent magnetic, disturb- 



'mli<r 21, 1SS2, 1 a. ui. to 3 j). ni. At 1 a. in. there was a curved .yellow band in the >'\V. 

 (brightness _') from just below Aquihe towards Pegasus, but more or less obscured by the bank of 

 clouds that lay on the western horizon, and still more obscured at 1.15. At 2.15 a. in. an arched 

 band, somewhat Minions (brightness i 1 ), from Hercules in the, NNYV. through < 'onma Horeaiis, Canca 

 Ycnatici, Leo. and Leo Minor, ending in the haze. It was gradually breaking into streamers. It 

 had risen at 2.15 about 5" J higher, with considerable, llickering vibration in the streamers, showing 

 pale colors, ;;rcen. yellow, and red, not rose (brightness J to.'!); and there was also a zone (brightness 

 1 to i'), with its starting points in the HE. and NYV., hidden by hazy clouds, and crossing the zenith 

 AY. ol' Polaris and drifting slowly westward. At 3 a. m. there was a rather pale band coming from the 

 clouds near Cancer in the ESE. across the zenith from Ursa Major to Cassiopeia and ending in the 

 clouds in the NN YV. At 3.15 it. was partly faded, and finally obscured by clouds. At 4 a. m. there 

 acre only traces in the 2f. through the clouds which now covered the .sky. At 5 a. in. bands with 

 streamers vibrating from W. to E. and back, yellowish in color, and brightness 1 to 2, ran from 

 Orion through Taurus and Aries to Pegasus. AtO a. m. a quiet band (brightness 1) extended from 



isus through Cygnus, Draco, and Ursa Major to Leo, while at S traces only were visible through 

 the haze. At 9.10, 10.10, and 12.10 faint traces were seen. At 1 p. m. the aurora was extensive 

 in bands and streamers (brightness to 1), paling and vanishing quickly. The bands extended from 

 Gemini and Auriga to Ursa Major, and from Hercules through Corona Borcalis. and Canes Vena- 

 tici to Leo Minor; the streamers through Cygnus and Lyra and from Ursa Major to Ursa Minor, 

 forming half a corona. There were also streamers up from Bootes. At 2.12 p. in. there was a 

 sinuous band (brightness to 1) in rapid motion, starting near Taurus and running through Perseus 

 and Cassiopeia to Cepheus. At 3 p. in. there were faint traces of a, band and a few streanu TS in the 

 X. and XXYV. The needles were more or less disturbed during the whole twenty-four hours, the 

 disturbance being at its highest at 2 and ','> a. m. 



December 21 and 22, 1882, 11^;. m. to 11 a. m. At 11 p. m. there was a faint streak through 

 Bootes. Coma Berenices, Leo Minor, and Gemini. At 12.15 a. m. there was a faint regular arch 

 through Orion, Gemini, Leo Minor, Coma Berenices, and Bootes. At 1 to 1.15 a. m. the arch was 

 still narrow and greenish (brightness 1), from the ESE. to NNW. through Cauis Minor, Cancer, 

 Leo Minor, Canes Venatici, and Bootes to Serpcus. At 2 a. in. there was a very pale and some- 

 what sinuous band (brightness to 1) from Mouoceros in the SE. through Orion. Taurus, Perseus, 

 Cassiopeia. Cepheus. and Cygnus to Hercules in the NAY. This had drifted W. to Andromeda at 

 2.15, and a short band had developed in the SE. from Canis Minor to Leo (brightness 1 to 2). This 

 band was rather broad, and llared into short hazy streamers on the upper edge. At ''> a. in. there 

 was a broad zone of the usual typo across the zenith from Mouoceros in the ESE. to the NAY., 

 whcreits base occupied 20 in .azimuth in Hercules. The eastern boundary passed through Leo 

 and Ursa Major, while the main zone spread west to Cassiopeia, and the northwestern bauds 

 readied Andromeda and Pegasus. At .1.1 3 it was brighter (brightness 1 to 2) and had spread 

 about 10 each way. showing faint, tinges of color in the E. and broken into cloudlikc masses in 

 the S\V. At 4 a. m. only the extreme western part of the eastern baud remained, and the whole 

 had faded to traces at 4.15. Ai 5 pale traces of bands crossed the zenith from N. to S. At (i a. in. 

 a \cllo\vish, quiet band (brightness to 1) ran from Pegasus through Perseus, Auriga, and Gemini to 



er. At 7 a. m. there were quiet bauds (brightness to 1) from Orion through Taurus, Auriga, 

 Lynx, and l.'rsa Major to Leo and Coma Berenices. 'Faint traces were seen over the southern 

 horizon at S a. m., and the last faint traces were noticed at 11 a. m. The needles were quiet up to 

 ;: a. m., when they were considerably disturbed, the horizontal force lu-ing most ejected. This dis- 

 turbance lasted three hours, and there was another slight disturbance at 5 and ('. a. m. 



Hi, -nnl-,-1- 22 and I':!, 1SS2, 1 1.55 p. m. 1o"2 p. w.At 1 1.55 p. m. there was a pale, regular arch in 

 the NF.. from N.NYV. to ESE., the altitude of the crown being about 25 . This had wholly disap- 

 peared at 12 midnight. Nothing more was observed till 2 a. m., when there was a broad, hazy 

 band across the zenith from Monoeeros, in the. ESE., to Hercules in the NVY., through Gemini, 

 Auriga, Camelopardalis, Crsa Minor, Cepheus, Cygnus, and Lyra. This had drifted west and faded 

 to a trace at 2.15, and in the NE. there had developed three or lour sinuous and ,'omewhat convo-
