Saturn does not rise till after midnight on the last day 

 of December, and we therefore defer giving an ophemeris 

 of him until next year. He is occulted by the Moon, 

 though the phenomenon is not of course visible in the 

 British Islands, on the evening of the 12th. Uranus does 

 not rise before 3 a.m. at the end of the month, and is 

 therefore, for the purposes of the amateur observer, 

 invisible. 



Neptune is an evening sta^r, and is excellently situated 

 for observation, coming into opposition with the Sun on 

 the 1st, at a distance from the earth of about 2,680,700,000 

 miles. He rises on the 1st at 3h. 54m. p.m., with a 

 northern declination of 20° 22', and an apparent diameter 

 of 2-7"; on the last day of the month at Ih. 53m. p.m., 

 with a northern declination of 20° 15'. During December 

 he describes a short retrograde arc in Taurus, between 

 T and e, to the N.E. and N.W. of the 5| magnitude star 

 Weisse's Bessel-, ivh. 650. At llh. 40m. p.m. on the 2nd 

 he will be 1' ' due north of a 9tli magnitude star. A 

 map of the small stars near his path will be found in the 

 Enc/lish Mechiinic for October 28th. 



December is a fairly favourable month for shooting stars, 

 the chief showers being those of the Gemiuids on December 

 9th — 12th, the radiunt point being in r..\. 7h. Om., and 

 north declination 32°, rising about 4h. 10m. p.m., and 

 setting at Ih. 40m. a.m., and of the Andromedes, occurring 

 on the evenings of the 26th and 27th, the radiant point 

 being iu r.a. Ih. 40m. and north declination 43', the 

 shower being circumpolar. It seems probable that a fine 

 display will occur this year. 



The Moon is full at 21i. 17m. a.m. on the 4th ; enters her 

 last quarter at 2h. 30m. a.m. on the 11th ; is new at 8h. 

 18m. a.m. on the 19th ; and enters her last quarter at 

 9h. 22m. p.m. on the 26th. She is iu perigee at 3-Oh. 

 A.M. on December 2nd (distance from the earth 224,630 

 miles) ; in apogee at l'3h. p.m. on the 15th (distance 



from the earth 252240 miles) ; and in perigee at 0-2h. 

 P.M. on the 31st (distance from the earth 222,320 miles). 

 She is at her greatest western libration at 5h. 48m. a.m. 

 on the 9th, and her greatest eastern at 5h. 21m. 

 the 24th.
