February 1,1883,5.15 <i. m.tu 1.15j>.w. Traces of small luminous patches appeared in the \vest at 

 5.15 a. in. At 0.15 a. in. one white and quiet band (brightness 2) ran from SE. to \VN\V. along tlie 

 horizon, while there was an arch of short streamers of the same color and brightness, somewhat 

 irregular, from the same starting points, about 10 higher than the first band, passing through I.eo, 

 Cancer, Gemini. Orion, and Taurus. At 7.15 there was a large corona (brightne.ss 2 to .".), centering 

 in Visa Major south of the zenith; and a bright baud of streamers, vibrating rapidly from W. to E., 

 ran through Pegasus, Aries. Taurus, Auriga, Gemini, and Leo Minor. At S.15 there was a broad 

 arch from ESE. to WNW., with the crown about 15 from the southern horizon, with a second sim- 

 ilar arch above it, from the same starting points through ])o<">tcs, Canes Venatici. I'rsa Major, 

 Lynx, Gemini, and Orion. From the western extremity came a third similar arch through Taurus, 

 Camelopardalis, Ursa Minor, Draco, and Hercules, ending near the eastern horizon. At the same 

 time a broad irregular broken band of short streamers, quivering slightly, extended from the ENE. 

 through Lyra. Cygnus, Laeerta, Andromeda, Triangulum. Aries, and the Pleiades (brightness of 

 all, 2;. At !M5 there were traces only in the S. At 10.15 there was a broad and quiet white arch 

 from I lie EKE. to YVNYV., with its crown about 15 above the southern horizon, and long white 

 motionless streamers in the E. and ENE., in Hercules, Sagitta, Cygnus. Lyra, and Draco. At 11.15 

 there was a broad waving baud from E. to W. through Gemini, Ursa Major, Draco, Lyra, and Cyg- 

 nus (brightness 1), and a long low arch in the S.; 12.15 p. m. there was a broad quiet band from 

 the E. to AY. from Leo through Coma Berenices, Boo'tis, and Aquila, with a corona in Ursa Major. 

 At 1.15 a corona, with its streamers thickest in the E. and AY., was barely discernible in the bright 

 twilight. The needles were comparatively quiet up to nearly half past 12 p. in., when a violent 

 disturbance began, which is still going on. 



F<'ltnD-y 2, 1SS.'?, 1 a. m. to 12.15 p. m. Early in the evening the ha/e and clouds were thick, 

 but at 1 a. in. (8 p. in. local) traces of twisted bands, apparently bright and in motion, were visible 

 through the clouds, crossing the zenith from 2s W. to SE. These were very faint at 1.15. The clouds 

 were thicker at 2 a. m., and the traces consequently fainter. None were seen at 3 a. m. At 4 the 

 haze grew thinner, allowing the central part of a broad zone to be visible. The starting points 

 were invisible in the haze in IS' AY. and SE., and the whole was much obscured by haze. In breadth 

 it reached from Ursa Major to Taurus. The sky was much clearer for four or live hours, gradually 

 becoming obscure again. At 5.15 an aurora was observed passing through Canis Minor, Orion, 

 Taurus, and Cetus (brightness to 1). At 0.15 there were two faint bands, one from Cancer 

 through Orion, Taurus, and Aries, and the other through Gemini, Auriga, Perseus, and Andromeda 

 (brightness to 1). At 7.15 a short band crossed the zenith from Hercules through Ursa Major, 

 Camelopardalis, and Gemini. Farther south of the zenith yellowish white bands ran from Ursa 

 Major to Canes Yeuatici, Coma Berenices, and Leo Minor, and there was a band of streameis. in 

 rapid waving motion, passing through Serpcns, Bootes, Coma Berenices. Leo. Cancer, and Gemini 

 (brightness 1 to 2). At S.15 there were only faint traces along the horizon. At 0.15 a broad, white, 

 quiet, irregular arch from the SAY. horizon through Cancer, Leo Minor, Ursa Major. Canes Yeua- 

 tici, Corona IJomdis, and Hercules, ending in Serpcns. At 10.15 the haze and clouds were again 

 becoming thicker, and traces of an arch were observed running from ESE. to YV. about 10' south 

 of the zenith. At 11.15 a broad zone (brightness to 1) covered most of the southern sky, the 

 bauds running from ESE. to AY. The first ran through Sagitta, Lyra, Draco. Ursa Major, and Leo 

 Minor, and the second through Hercules, Corona Horealis. Coma Berenices, and Leo. while a broad 

 irregular patch ran from the SSE. to SAY. through Serpens, Bootes, and Leo. with a smaller luminous 

 streak near the horizon in Virgo. The last faint traces were seen ;it 12.15 p. m. A magnetic disturb- 

 ance began at I a. m. and continued all night. 



i'l-bruanj .'!, ISSo, 1 a. in. i 11.15 . in. The sky was cloudy early in the evening, but the clouds 

 broke sufliciently at 1 a. in. (about 8 p. in. local) to show a regular, narrow arch in (he SYY. (bright- 

 ness 2', from the SE. to N\Y., with its corona at an altitude of about 40, partially obscured by 

 clouds. The arch was partially broken and irregular at 1.15. At 2 the haze was thick again, but 

 through it near the zenith in the SE. there were traces of an extensive and apparently bright au- 

 rora which was nearly obscured at 2.15. There was less haze a^ain at 3 and a broad band consid-
