AURORA BOREALIS AND OTHER METEORS. 



WELD; PRANKLIN COUNTY, MAINE. 



Bonarkahle Meteor. 



I 1850 — September 30, — At 9/i. 307n. p. m. I saw a remarkably 

 jgtrange meteor iu the southern sky. Its shape was that of an ellip- 

 ':ical zone or ring, and when first seen its centre was about 5° east 

 and the same distance north of FomaUiaut, or in R. A. 23/i. dm., 

 jind declination 25° 23'. Its longer axis lay in nearly an east and west 

 direction. The length of its transverse axis was about 10°, and of its 

 ?3onjugate diameter 5°. Width of the bright belt or annular surface 

 pn the upper part of the ellipse 2°, on its lower part 1°. The north- 

 ern part was very brilliant, but its southern part was dimmer. It 

 Inoved slowly to the westward, and also had a rotary motion. At 9/i. 

 iom. its centre was 4° north of Fomalhaut and on the same declina- 

 •ion circle ; being less brilliant tlian when first observed, but of the 

 drst noticed figure. 



i At 107i. its centre was in about R. A. 22A. 257/1., and declination 

 127° 23'. Its length was then nearly 15°, and width 3°. It was 

 icarcely perceptible. It disappeared at lOA. 10«i. 



STILLWATER, MINNESOTA TERRITORY. 



First Class Aurora. 



\ 1851 — Sppteniber 29. — In the evening there was a remarkable exhi- 

 bition of the Aurora Borealis. Soon after dark I observed a small and 

 jrilliantly white orch, having its point of culmination, which was about 

 10° above the horizon, very nearly, if nut precisely, in the magnetic 

 [meridian, in the north. (The magnetic needle has a variation at this 

 place of about 9:^-° east, epoch 1850.) Soon after this, deep red streamers
