Tlic Patli of Uranus from April 1st to September 1st, 1893. 



system beiiig 43" in diameter, and the minor 4f "). Saturn 

 will be occulted by the Moon on the 1st and 28th, but the 

 phenomena will only be visible in the southern hemisphere. 

 He will be in conjunction with the beautiful double star 

 y Virginis at 2h. 30m. p.m. on the 8th, the star being only 

 6' 2' north of the planet ; and on this and several preceding 

 and following evenings the planet and star will present a 

 charming appearance in the evening sky. This conjunction 

 is, curiously enough, not noticed in the Xauticdl AluKinar. 

 Ehea is in superior conjunction at 2-Oh. a.m. on the 1st ; 

 in inferior conjunction at 8'6h. p.m. on the 7th ; in superior 

 conjunction at 2-7h. a.m. on the 10th ; in inferior con- 

 junction at 9"2h. P.M. on the 16th ; in superior conjimction 

 at S'3h. A.M. on the 19th ; in inferior conjunction at 9-8h. 

 P.M. on the 25th ; and in Superior conjunction at 4'Oh. a.m. 

 on the 28th. lapetus is at his greatest western elongation 

 on the morning of the 13th. A map of the path of Saturn 

 during April will be found in the " Face of the Sky " for 

 March. 



Uranus is well situated for observation, coming into 

 opposition with the Sun on the 28th at a distance from the 

 earth of about 1632j millions of miles. He rises on the 

 1st at 8h. 58m. p.m., with a southern declination of 14° 19', 

 and an apparent diameter of 3-8", the apparent star mag- 

 nitude of the planet being 5-5 in the photometric scale. 

 On the 80th he rises at 6h. 54m. p.m. with a southern 

 declination of 13° 57'. The accompanying map shows the 

 path of the planet in Libra to the confines of Virgo from 

 April 1st to September 1st, all stars down to the 7th 

 magnitude being shown, and the position of the planet on 

 the first day of every month being marked with a cross. 

 The magnitude of the principal stars are : aV- Libra (pair), 

 3-1 I \ Virginis, 5'0 ; .' Libra, 5-5 ; LI. 25,965 Virginis, 

 5-6 ; fi and J- Librse, 5-7 ; ^' Librse, 6-0. All the remainder 

 are between the 6th and 7th magnitudes. 



Neptune is an evening star, but must be looked for as 

 soon as possible after sunset. He sets on the 1st at llh. 

 44m. P.M., with a northern declination of 20° 19', and an 

 apparent diameter of 2-6". On the 30th he sets at 9h. 

 56m. P.M., with a northern declination of 20° 28'. During 

 April the planet describes a direct path in Taurus, being 

 about 4|' south of the 5| magnitude star, Weisse's Bessel-, 

 iv. h., 650, on the evening of the 16th. A map of the small 



stars near his path will be found 

 in the KtK/linh Mechanir for 

 October 28th i 1892. 



Shooting stars are fairly plenti- 

 ful in April, the best marked 

 shower being that of the Lyrids, 

 with a radiant point in r.a. 18h. 

 Om. + 33°. The radiant point 

 rises on the evenings of the 19th 

 and 20th, when the maximum 

 occurs, at about 6h. 27m. p.:m., and 

 souths at 4h. 8m. a.m. 



The ^loon is full at 7h. 18m. 

 A.M. on the 1st ; enters her last 

 quarter at llh. 35m. a.m. on 

 the 9tli ; is new at 2h. 35m. 

 P.M. on the 16th ; enters her first 

 quarter at 5h. 26m. a.m. on the 

 23rd; and is full at llh. 23m. 

 P.M. on the 30th. She is in 

 apogee at 7h. p.m. on the 5th 

 (distance from the earth 251,840 

 miles), and in perigee at lOh. p.m. 

 on the 17th (distance from the 

 earth 223,600 miles).
