/.OIK- o!' ninny bands (brightness It to 1) apparently covering most of tli:- sky. The sky \vas again 

 partially clondy at the next observation, and traces only wen- visible. At (i.15 one band with 

 streamers in rapid vibration from \V. to E. passed through Bootes, Canes Vcnatiei, Ursa Major, 

 Lynx, and Draco, while a second band, wholly of streamers in rapid motion, ran from Leo to 

 Gemini, with a lew patches in Virgo and Boiiles (brightness I to 2). At 7.15 a quiet band (bright- 

 ness 1 1 crossed the zenith from Hercules through Draco, 1'rsa Minor, Camclopardalis. Auriga, 

 and Taurus. There were nothing but traces at 8.15, nor was any observed for two observations, 

 though the sky was clear, but at the next two observations traces were observed near the xenith 

 at 10.15 and in the SW. at 11.15. At the next hour it was daylight. There was :i slight magnetic 

 disturbance at 10 a. m.

 ington), when the clouds cleared away, leaving the sky covered with haze, through which a some- 

 what sinuous band wa.s visible (brightness apparently 1), crossing the zenith from near the horizon 

 KXW. and ESE. This had broadened into a zone at 3.15 with one bright streak (brightness 1 to 

 2) in the NW. Most of the stars were obscured. At 4 the sky was much clearer, and there was 

 an arched band (brightness 1 to 2) from the XX W. in Pegasus to E. by S. in Virgo, through Cygnu.s 

 (e), Lyra (just below -), Hercules, Serpens. and Bootes. At 4.15 it was paler (brighSiess 1), ami 

 growing double from the eastern end. It began to cloud again at 5. so that traces only wen- 

 visible. There was a considerable magnetic disturbance between S a. m. and 1 p. m., reaching its 

 maximum at 11 to 12. 



Fcliriuiri/ IS. 18S3. 11.15. m. to .'. The weather was cloudy all night, but traces of aurora 



were visible through the clouds at 11.15 a. in. The magnetic needles were very quiet. 



i-'tlntanj 20. 1*83. 8 ti. m. to ii.15 a, m. The weather was cloudy most of the night, but cleared 

 away sullieiently at S to 8.15 and !> to 0.15 a. in. (3 and 1 a. m. local) to allow aurora to be seen. 

 This consisted of traces merely at the first observation, but at the second of' two quiet bands 

 (brightness t) to 1), one from Auriga through Perseus to ( 'assiopeia. and the other from Andromeda 

 through Pegasus to Delphimts. The magnetic needles were considerably disturbed from 4 to 1 1 

 a. m., the disturbance reaching its maximum at 7. 



Primary 21 and 22, 1883, 11.45 p. m. io 11.15 a. m. The twilight had not completely faded at 

 7.i;0p. m. (11.45, Washington), when a twisted streak tinged with yellow was observed crossing the 

 zenith from NAY. to SE. (brightness to 1). By 12.15 a. in. this was reduced to a bunch of stream- 

 ers in (.'ygnus and Lyra, and a faint baud through Lyra, Hercules, and I'rsa .Major, and had wholly 

 disappeared at 1 a.m. At 1.15 shifting, twisted streaks and bands of streamers with considerable 

 motion, (biightness Otol), tinged with yellow and rose, appeared in the X., occupying Lyra, ('ygnus, 

 Cepheus, and Draco. At 2 a. in. a very pale band ran from Cygnus () in XXW. throngh Draco 

 and Ursa Major (). ending in the moonlight ESE., and was wholly gone at 2.15. At 3 a. m. then- 

 was a pale band west of the xenith, from the XW., in Pegasus, through Andromeda. Cassiopeia, 

 Auriga, and Gemini. This was replaced at 3.15 by a similar band in nearly the same position as 

 the .ne observed at 2 a. m. Traces merely were observed at 4 to 4.15. At 5 two bands ran from 

 Bootes and Virgo through Coma Berenices. Leo. Leo Minor. Gemini, and Auriga to Taurus, with 

 bunches of slowly vibrating streamers in Bootes and Virgo (brightness to 1). Traces only were 

 observed at <J and s. At 0.15 there was a quiet arch (brightness to 1) in the S. from ESE. to 

 WNW., with an altitude of about 15, and a quiet, striated arch (brightness (I to I) through Her- 

 cules. Draco, and Gemini. At 10.17 a. m. the arch in the S. was unchanged, while a second similar 

 arch about Id to l.Y in breadth ran from ESE. to SW., while a third arch ran from KXE. through 

 Cygniis. 1'isa Minor, and Lynx to Cancer, with streamers in the X 1C. and a luminous patch in 

 Gemini lall brightness to 1). At 11.15 there was a well-delincd yellow corona : brightness i' , 

 quivering rapidly, occupying Cygnus, Hercules. Corona Borealis. Bootes. Canes Venatici, Leo 

 Minor. I'rsa Major, and Ursa Minor, also Auriga and Perseus. The needles were considerably 

 disturbed all night, the disturbance reaching its maximum between 10 a.m. and 12 m. 



I'rlinuinj 22, anil 23, 1883, 1.55 p. in. to 8.15 a. m. At 11.55 the aurora consisted of indistinct 

 patches and s! reamers in the XK.. which at 12.15 a. in. had developed into a faint corona, center- 

 ing in Camclopardalis. It was made of shifting streamers, which were short, except in the XYV. 

 suid SE. At 1 there was a- broad, highly modified zone occupying large parts of the sky, made up
