 Clear. 



Nov. 5th. — A great coronal aurora about llh. I did not see it. Seen early in the evening 

 at Norfolk, Conn., by Mr. R. Gaylord, but overlooked here. 



Nov. 14th. — It was then clearing rapidly. Magnificent rose-red auroral li^ht covering the en- 

 tire hemisphere ; brightest about 6h m. t. Needle exceedingly disturbed. [See Dec. 29th, 1842.] 



Nov. 17th. — Slight A.B. to 8h or until moon rose; after which it could be seen. 



Nov. 18th. — I saw no streamers; but early much diffuse reddish light; after, a distinct arch, 

 with vertex about 5° high and dark segment beneath, all fluctuating and ever changing ; loud 

 roar of waves (probably those of the Atlantic) distinctly audible. 



Nov. 20th. — Mr. J. H. Dulles and Mr. J. D. Whitney report a single streamer seen by them 

 about llh ,50ni. 



Nov. 30th. — An aurora is reported to me which must have been considerable, but much 

 obscured by clouds. I was in the house most of the evening. 



Dec. 5th. — A few red streamers in N.E. about 5h 45m reachmg to zenith, not much seen after ; 

 evening, especially latter part, very unfavorable. I did not see it at all. 



Dec. 7th. — Yet a faint one suspected, but uncertain on account of moon.
