a. in. two yellowish green Iw.nds ran from V.'.SW. to \VNAY., through Aquila to Hercules, with a 



lew streamers on the AY MY. end (bright!) 2). At <> a. in. there were several bands and 



the northern sky. the streamers vibrating from YV. to K. At 7 a pale arch with stream- 



an from the SK. to SNY., about 9 or 10 above, the horizon (brightness 1). At 8 there was a 

 sheaf of beams in the NNE. from l.eo to Camelopardalis, with slow lateral vibration, changing in 

 brightness from 1 to 2. At 9 a. m. the horizon was encircled by a band of pale quiet white light 

 10 in breadth, from which arose a perfect fringe of streamers, some approaching the zenith, most 

 of them, however, not exceeding 10 or 15 in length, ami apparently motionless. This display 

 continued for nearly an hour, with but slight change, when a broad white band (brightness to 1) 

 was observed to start from the luminous base in the AY. through the Pleiades and Ursa Major, 

 stopping at a point about 30 E. of the zenith. No farther change was observed till 11 a. in., when 

 a second like arch was formed about G-8 in breadth and G<P in diameter, having its crown in the 

 zenith. From this band streamers shot out and formed a complete corona. At This time the mag- 

 netic disturbance was particularly great. The corona continued apparently unchanged and motion- 

 less until it faded before the dawn. 



.Yon 'title > 1- and 13, 1882, 9.30 #. in. to 11.30 _/>. m. As soon as the sky grew dark enough for 

 an aurora to be visible, it appeared well developed and probably a continuation of the preceding 

 aurora. At 10.17 p. in. a waving band of light extended across from SE. to NAA'., brightest in the, 

 SE., where it had the curtain form, with the streamers in the same direction. At 11.17 there was 

 a faint streak (brightness 1) through Andromeda, Cassiopeia, Draco, and Bootes, with bright cur- 

 tains in Pegasus and Cygnus. At 12.17 there was an arch whose extremities l^rc SK. and NAY., 

 and below this, on the horizon, a well marked dark segment, with wavy faint: streamers above it, 

 and faint patches of light in Andromeda and Cassiopeia. At 1 a. m. there was a broad bright zone 

 occupying nearly all the western sky, and extending east of the zenith, from Bootes, in the NNAY., 

 through Ursa Major, round above Capella to Taurus, in the ESE. The zone was composed of sev- 

 eral broad sinuous bands, converging near the horizon, and sometimes developing streamers (bright- 

 ness 2 to 3). It drifted westward, and had passed the zenith at 1.10, in motion especially on the 

 edge, iu the N.. and at the zenith, waving and vibrating, with, some slight display of colors, yellow, 

 green, and rose. There was a particularly bright portion in tlie SE. The whole had sunk low in 

 the S\Y. at 1.17. From 2 to 2.17 a. in. the aurora was reduced to two bands lying low in the S\Y., 

 twin Ophiuclms in the NW. through Aquila to Pegasus in the S., with streamer;; from the upper 

 band, all growing gradually smaller (brightness 2 to 3). At 3 a. in. a broad bright zone of the 

 usual type crossed the zenith from Orion and Taurus in the SE. to Bootes, with streamers forming 

 a half corona E. of the zenith, centering in Cassiopeia (brightness 2). At 3.10 the, half corona was 

 \Y. of the zenith, with the bauds as before, developing wavy curtains at the zenith. At 3.17 there 

 were bands low in the NE., running from Trot-yon through Leo Minor ami-Canes Yenatiei to Bootes, 

 made up of streamers .flashing rapidly from N. to S., and showing beneath them a well-marked 

 dark segment (brightness 2 to 3). At 4 a. m. these bauds had become curtains ; there was a broad 

 baud (1) in the S. and sinuous streaks covered most of the sky at right angles, roughly speaking, 

 to the magnetic meridian, converging towards the horizon in the NW. and SK. At 4.10 to 4.17, 

 radiating from Aquila in the N\Y.. near the horizon, and Canis Major, near the SIC., bands, streaks. 

 and streamers covered most of the sky, constantly changing and shifting, with much Ilickcring 

 motion. There ua.> a special center of activity in the. N., where curtains were developed. At 5 

 the aurora consisted ot two bands, with yellowish streamers. At C it was an arch made up of cur- 

 tains and streamers in rapid motion (brightness 2 to 3). At 7 there were, only faint traces around 

 the horizon, while at 8 no aurora was visible, but it broke out again at 9 in the form of a white 



>ted baud (brightness 2 to .">). about ;><P in width, passing from the SK. to NAY., about 3 to 5 

 SW. of the /cnith. There was much wave-like motion from AY. to E., with considerable change of 

 form, but not ot' position. The horizon was fringed with streamers, generally about 20 long and
