 seen. 



Feb. 4th. — Mr. Lucius W. Fitch states that he saw an undoubted A.B. through thin and scat- 

 tered clouds, before midnight. 



Feb. 7th. — Between lOh and llh partly clear, and a moderate A.B. I saw it but imperfectly. 

 Some streamers. [Mr. S. D. Pardee saw about 4h a.m. of 7th red auroral light through open- 

 ings in the clouds.] 



Feb. 8th. — A.B. moderate, a general light along N. horizon, perhaps 5° altitude and 80* am- 

 plitude, and at 8h and lOh a pretty well defined belt, low down. I saw no streamers. 



Feb. 20th. — From 5h SOm to (Jh VZm a.m. of 31st A.B., chiefly red. Streamers through ampli- 

 tude of 90° or more, and 20° to 40° high. [At Cumberland, Md., Professor Forrest Shepherd 

 saw, at 7h 30m of 20th, red auroral blushes in N. Sky clear there.] 



Feb. 21st.— Up to 8h only a bright diffuse arch-shaped bank, 10° high. After 8h streamers 

 30° high, and much red light. At lOh N. entirely overcast. 



Feb. 23d. — Chiefly a light of 60° or more amplitude along N. horizon, clear and sometimes 

 bright. Between Sh and'9h several bright streamers, none higher than 30°. 



Feb. 24th. — A.B. not very conspicuous from 7ti to 8h. Within from 8h to 9h. At 9h and soon 

 after, several streamers mingled with red patches ; amplitude 60° to 75°, altitude 20° to 30°. 

 At lOh some bright streamers. 



Feb. 25th.— Suspected a faint auroral light, but could not determine to lOh. Saw at 9h (?) 

 what appeared to be a streamer. 



Feb. 26th.— Not noticed until between 9h and lO'n, then several faint streamers reaching up 

 to W or 15° ; about lOh a diffuse light, brighter than before, but yet faint.
