POSITION OF PLANETS FOB JUNE, 1877. 239 



POSITIONS OF PLANETS FOR JUNE, 1877. 



Observatory of Yassar College. 



The computations and some of the observations in the following notes 

 are from students in the astronomical department. The times of risings 

 and settings of planets are approximate, but sufficiently accurate to enable 

 the ordinary observer to find the object mentioned. M. M. 



Mercury.— Mercury rises on June 1, at 4h. 19m. a. m., and sets at 6h. 

 29m. p. M. On the 30th, Mercury rises at 3h. 17m. a. m., and sets at 6 p. m. 

 The best time for seeing the planet is on the morning of the 20th, when it 

 is furthest from the sun and rises an hour before it. 



Yenus. — On June 1 Yenus rises at 4h. 57m. a, m., and sets at 7h. 57ra. p. 

 M. On the 30th, Yenus rises at 5h. 4:1m. a. m., and sets at 8h. 35m. p. m. 

 Yenus is small but bright, and after the middle of the month it can be seen 

 for nearly an hour after sunset, following almost exactly the path of the 

 sun. 



Mars. — On June 1, Mars rises a little after midnight and sets at lOh. 

 25m. in the morning. On June 30th, Mars rises at 11 p. m., and sets at 9h. 

 38m. the next morning. Mars is in southern declination among the small 

 stars of Capricornus and Aquarius, but is moving toward the north, coming 

 into better position and increasing in api^arent size. 



Jupiter. — Jupiter is brilliant now in the southern sky, and will be in its 

 best position about the middle of June. On the 1st, Jupiter rises at 8h. 

 50m, p. M., and sets at 5h. 51m. the next morning. On the 30th, Jupiter 

 rises at 6h. 41m. p. m., and sets at 3h. 41m. a. m. the next day. Jupiter 

 souths at midnight on the 20th, at an altitude of 25° 10' in this latitude. 

 The various changes of Jupiter's four moons can be seen with a small tele- 

 scope, and many of the most interesting occur in June. On the 12th, Jupi- 

 ter will be seen with only three moons until after 9 p. m., when the 1st 

 moon will reappear from behind the planet. On the 19th, the 1st satellite 

 will disappear between 8 p. m, and 9 p. m,, by passing behind the planet, and 

 between 10 p. m. and 11 p. m. the largest will disappear by coming in front 

 of the planet. On June 26, Jupiter will be seen when it rises, with all four 

 moons ; but a little after 10 p. m, the first will disappear by the planet pass- 

 ing between us and the moon and hiding its light ; this satellite will reap- 

 pear in 2h. and 24m., and for a little over an hour the four moons are still 

 seen. But the 3d or largest is very near the planet, and a little after 2 a. 

 M. comes in front of and is lost in the light of Jupiter, The small stars 

 around Jupiter are those of the constellation Sagittarius. 



Saturn. — Saturn rises on June 1st, at Ih. 5m. a. m., and sets at Oh. 23m. 

 p. M. On the 30th, Saturn rises at llh. 10m. p. m., and sets at lOh. 29m. a. 

 M. of the next day. Mars and Saturn rise at nearly the same time on the 

 30th, but Saturn is 5° further north. 



Uranus. — On the 1st, Uranus rises at 9h. 57m. a. m., and sets at llh.
