Clear at Riduficld; very stronirly sus]>eetetl an A.B., but saAV no 

 streamers: noticed it at intervals from 0'' to lO*". 



Clear; slio;htly suspected some auroral liu'lit about 9'' or 9^''. 



Clear. First noticed ab't Si'' an A.B. ; a band-sha])e(l mass of light. 

 I did not watch for streamers. About 10'' it had increased in 

 brightness and extent. Not a very regularly s]iai)ed arch, but 

 a mass of liglit extending perha])S 65° or 70°, and quite red, par- 

 ticularly that portion W. of X. There Avere numerous red 

 streamers, some of them extending u)> 40°. 



Clear. First noticed a bank of auroral light about Sf' ; Avatched it 

 at intervals up to 10:^'', Init saw no streamers certainly. It 

 changed very little during the whole time. 



Clear. Xotieed about S"", an arch-shaped bank of auroral light, 

 not over 2° or 3° high. At 10'' it had increased in brightness, 

 extent, and elevation. Amplitude about 60° or 65°, and 5° or 6° 

 high; pretty Avell formed. Saw no streamers certainly, but 

 thought I observed one occasionally extending upward 4° or 5° 

 from the arch. 



Partly clear at 7^'. Ov't at 8fi' and 9''. At 11'' clear, suspected an 

 A.B., not a very good obs. 



Partly cl'r at 8'', but a cloud on the earth. Moon. Xo A.B. to ^^. 



Ov't 'to 11'' and probably later: at 12" clear X. and W. Thought 

 there was an A.B. * (482) 



Quite hazy. Xo A.B. at 8''; yet it Avas quite light among the 

 openings or thinner haze. At lO'' ov't. 



Clear. Saw alxnit 9:^'', a bright A.B. with streamers. It increased 

 in magnitude and splendor, and nearly equaled those of 1837-39. 



Cl'r, m'y : no A.B. to 10'' : very slightly susp. taint aur. light ab't 9'^. 



Clear. About 8'' first noticed, Avhile in the observatory, an auroral 

 arch with innumerable streamers. It increased in splendor and 

 magnitude till ll*". At 9^'' first noticed an arch of light span- 

 ning the heavens from E. to W. and passing S. of the zenith. 

 About 10'', Pollux was in the middle of the band, Avhich was 

 moving South. During all the time innumerable streamers, 

 tinted gi-een and ]mr])le, Avere marching and countermarching, 

 performino; evolutions indescribable. At 10^'' sheets of light 

 swept upAvard. 



X. slightly obst. to 9'', at 10'' Avholly ov't. Moon. Saw no A.B. 



Entirely ov't at 9'' : noAv and then a little clear sky. At 9^'' quite 

 a light streak in X. Ioav doAvn ; probably oAving to moon and 

 contrast of light and dense clouds. 



Ov't except here and there a fcAv stars to be seen. Thought it 

 quite light in the X.E. through the openings in the clouds; 

 presume it Avas the contrast. 



Mostly clear, some clouds on horizon ; hazy, yet stars tolerably 

 conspicuous. Xo A.B. to 10'', yet a light in the X. attracted at- 

 tention ; think there Avas no A.B. 



Ov't, and a shoAver about 8^'' ; nearly clear at 9^'* and no A.B. : 

 clouds interfered very much. Api)eared quite light through some 

 of the openings before and alYer 10''. 



Entirely ov't 9'' to 10'' ; clear from 7^'' to about 9'' and no A.B. 



Thick clouds; entirely ov't to lO**. 



Clear. First noticed an A.B. about 9''. At 9f' ' a fine arch about 4** 

 high, ampl. about 60° ; very soon a second one formed, 7° high
