Bradley'' s Auroral Register. 



and ampl. 90° more or less ; but cut off at Eastern end. Both 

 arches rose upward gradually, soon after Avhich the upper one 

 broke up into patches of light, Avhich continued to move south- 

 ward : quite ill-defined. The first arch continued tolerably per- 

 fect to lO^^"", when I ceased looking at it from the observatory. 



Clear. A.B. I first saw streamers "i" to 10" high about 8:^'', with- 

 out much other light, though the moon Avas shining. The moon 

 set about 10'', after which and even before, there was a segment 

 of an arch 4° or 5° alt. and 60° to 70" ampl. About the time the 

 moon set, the arch had become mere patches of light. Some few 

 streamers then. 



Cl'r : no A.B. to 10^'' ; there m\'is a slightly suspicious light in the N. 



Slightly suspected an auroral light, between 7f'' to 8^, but too 

 cloudy and too much moonlight to determine with any certainty. 



Much clouded to 10''. Clear in the X. at 10^^ and to ll"". Slight- 

 ly suspected an A.B. at ll''. It may have been occasioned by 

 the moon which was in quadrature. 



Slightly suspected an A.B. through an opening in the clouds about 

 8''. Entirely ov't in a few minutes: moon. 



Cl'r to ab't 94^'' ; think there was no A.B. yet a faint auroral light 

 slightly suspected at times. Ov't at 9f*'. 



Clear to 7'' ; ov't to 10''. Mostly cl'r at 1 1''. Was there an A.B. ? 



Clear. Slightly suspected auroral light at S''. 



Clear. Slightly suspected a faint auroral light, but am inclined to 



think that there was none. 

 Ov't to 10''. Clear at 12" ; saw no A.B. : poor obs. 

 Ov't early : at 1 l^V'' cl'r, and perhaps earlier ; saw no A.B. : poor obs. 

 Cl'r, Strongly susp. an aur. light ab't 8'' ; saw no streamers : moon. 

 Clear. No^A.B. at 7" to IV" : none at 9". Suspected A.B. at 1 1^*" ; 



not a very good obs. 

 Ov't to 9'' and doubtless later, snowing at 8^''. Mr. Pardee saw an 



A.B. through an opening in the clouds about 6 a.m. of the 7th. 



It was of a red color. (483) 



Clear. Moon. About 9'' to %\^ suspected some auroral light, but 



was uncertain, 

 Cl'r. Strongly susp. some aur. light ab't — *", but at 10^^ concluded 



there Avas none. 

 Nearly clear at 9f ''. No A.B. seen ; some clouds in the Avay. 

 Almost AvhoUy ov't to 9'', partially clear at times. N. obsc. at 10^. 

 Clear. Strong suspicions of a sl't A.B. ab't 9'' : saAv no streamers. 

 Clear. About 9|^'' suspected a slight A.B., but a few minutes Avatch- 



ing confirmed it, as I saw one streamer distinctly, and two or 



three others faintly : the one reached up to about 7" or 8° alt. E. 



ofN. At 11 1" ov't. 

 Almost wh'y ov't to 10''. Through an opening in the clouds ab't 



9^'' slightly suspected some A.B., but Avas uncertain. 

 Almost Avh'y oA^'t from 9'' to 9^". Clear at 10^'' ; could see no A.B. 

 Sky much obsc. by clouds. No A.B. seen from the observatory. 

 Ov't entirely to 9''. At 9f'' saw the light of an A.B. above the 



trees ; could not be mistaken : saAV no streamers. 

 Clear, and no A.B. at 12". 



Clear. A.B. slightly suspected about 9'', but think there was none. 

 Clear. No A.B. seen at 8^1^, nor at 10''. Not a very good obs. 

 Ov't early. M'y cl'r at 9^'', but hazy in N. SaAV no A.B. : poor obs.
