ASTRONOMICAL INFOUMATION. 



To the Editor of the PhilosojMcal Magazine and Journal. 



Sir, NEW COMET. 



TN the night of the 28th ultimo, a faint appearance of a 

 -*■ comet was observed here ; but from the lunar light and the 

 passing clouds its true position could not be ascertained. It 

 was again seen here with more favourable weather for obser- 

 vations, between 9 and 10 o'clock p.m. on the 7th instant, 

 nearly in the S.E. point, in the right side of the constellation 

 Cetus : the nearest star to it was the one marked u in the under 

 })art of the belly of the "Whale. Its train was then inclined to 

 the east, from its position with respect to the sun, and be- 

 tween ten and eleven degrees long, extending to the star Baten 

 in the body of that constellation. 



Its nucleus was just perceptible with the naked eye at inter- 

 vals, and the apparent size of a star of the fourth magnitude, 

 surrounded by a large circular coma fifteen minutes in diame- 

 ter, and of a brilliant appearance, so that it was seen through 

 attenuated haze. Its distance from the sun was 166 degrees, 

 the first comet we have ever seen at so great a distance from 

 that luminary. 



It was again seen here in the nights of the 13th and 11th, 

 with a very low altitude when on the meridian, but not so 

 bright, nor the train so long by four degrees as in the night 

 of the 7th.
