Bradley's Auroral Register. 



Clear. No A.B. Saw a well defined strip of light about 40° long, 

 resembling the comet so much that I took it for one at first sight ; 

 but it moved pretty fast sideways. It was below the pole about 

 4° or 5"^ when first seen (at 7:^'') ; moved upward and eastward 

 until it pointed 5° east or south of Arcturus, when it was faint 

 and just distinguishable — a curious sight : I called it an auroral 

 streak ; extent about 20° east and west of Pole star (40° long) ; 

 could discover no other traces of an aurora. There were none 

 at 9^. Its light was a little stronger than that of the comet on 

 the 11th or 17th, but resembling it very much — decidedly diver- 

 gent from one end ; greatest Avidth not over 1° till nearly extinct 

 when it appeared perhaps 1:^" or 1^°, losing its end first and be- 

 coming pretty uniformly Avide. 



Clouds on the northern and western horizon. An aurora about 7^'' ; 

 uncertain Avhen it disappeared : no streamers. (Should probably 

 be Apr. 6th.) 



Heavy cloud on western and northern horizon, above it apparently 

 brighter than an ordinary sky ; saw no streainers at 9''. Rain 

 from %}? to 10i^ Cloudy at 10^'^. _ (479) 



Cl'y in N. at 9*^ ; tolerably clear in S. hemisphere. 



Cloudy. Tolerably clear "at 1U^ No A.B, 



Not very clear in north at 8'' or 9"^ ; saw no A.B. 



Clear at 10'', No A,B. 



SomeAvhat cloudy in north. No A.B. at lO''. 



Cloiidy. Clear spaces in the north at about ll'' 

 A.B, No streamers seen. 



No A.B, Rather hazy at 10". 



Mostly cloudy: clear spaces of sky in N, : no A.B. at ll'' : moon. 



Clear. First saw an auroral bow in the N, at '6^^ not very well 

 defined, rather faint, about 5° or 6° at highest part ; no stream- 

 ers. Noticed it until 7*". Looked again at lOf", — then a gene- 

 ral brightness, perhaps 12° or 14° high, the brightest part E, of 

 N. Moon rose about 9:^'' and very much interfered. The light 

 in the north Avas of a red color. 



Cloudy to Hi*"; very clear on morning of 25th at h^ \ strongly 

 suspect an A,B, — probably Milky Way, 



Clear, \Va.s uncertain Avhether there was an A.B, east of north 

 near horizon at 8f *>, or not ; seemed to be lighter there than in 

 neighboring portions of the heavens. Moon near quarter. 



Here "and there a clear space, but at 11'' ov't, and prob, all night. 



Ov't to ll'\ Clear next morning at 4", No A.B. 



Clear. Moon, No A,B. to 12''. 

 Clear, Think there was no A.B, 

 Clear to 11'', There may haA'e been a slight A.B. at 11''; did not 



look critically. 

 Alternately clear and cloudy. No A.R at 11''. 

 Cloudy to 9^^'', Avhen it began tx) be clear. Clear at lli*", except 



loAV cloud in N. SomeAvhat cloudy at 12^'', Moon, 

 Cloudy to 10'', and doubtless later; two or three clear streaks in 



the north looked rather bright, but think there was no A.B, 

 Cl'y to about 9|'' ; cl'r in N, af 10:^'' : very bright, but think no A.B. 

 Ov't to 81"; between that and 11" cle^red'off. No A.B, at 11''. 



-Cloudy and rainy next morning.
