THE FACE OF THE SKY FOR AUGUST. 



By A. Fowler, f.r.a.s. 



The Sun. — Ou the 1st the sun rises at 4.'Jo, aud 

 sets at 7.47; ou the 31st he rises at 5.13, and sets 

 at 6.47. The disc should be carefully watched for spots. 



The Mooy. — The moon will enter last quarter ou the 

 7th at y.2 A.M.. will be new on the 14th at 8.28 a.m., 

 will ent«r first quarter on the 22nd at 7.52 a.m.. and will 

 be full on the 29th at 8.21 p.m. The following are the 

 oectiltations visible at Greenwich during the month : — 



The Planets. — Mercury is a morning star throughout 

 the greater part of the month, being at greatest westerly 

 elongation of 19° 23' ou the 2nd, and in superior conjunc- 

 tion on the 27th. 



Venus is an evening star, setting about an hour later 

 than the sun throughout the month, and therefore not 

 conveniently situated for naked-eye observation. On the 

 15th the illuminated part of the disc is 0'873, aud the 

 apparent diameter 11"'S. 



Mars is still an evening star, setting about 9.42 p.m. on 

 the 1st, and about 8.15 p.m. on the 31st. The path of 

 the planet is from near y Virginis to near the eastern 

 boundary of Virgo, passing a little north of Spica on the 

 ISth. The apparent diameter diminishes from 5'''4 to 5"-0 

 during the mouth. 



.Jupiter will remain a very conspicuous object in the 

 evening sky iu spite of his low altitude. He is on the 

 meridian at 9.40 p.m. on the 1st, and at 7.37 p.m. on 

 the 31st, the apparent polar diameter diminishing from 

 42"2 to 39"0. The path is westerly, through Sagittarius, 

 until the 30th, when it will be stationary. The more 

 interesting satellite phenomena at convenient times are as 

 follows: — 



■rly part of Ophiuchus, 

 and T) Ophiui'hi. The 

 Isf at S.S I'.M,. ;ind mi 



Saturn is also in Sagittarius, a little to the east of 

 Jupiter. He crosses the lucridiau on the 1st at 10.9 p.m., 

 and on the :>lst at 8.6 p.m. On the 13th the a))pareiit 

 diameter of the planet will be 16"-(;, and the major and 

 minor axes of the outer ring respectively 4l"'7 and 17"'9. 

 The northern sjde of the ring is jiresented towards the 

 earth. 



Uranus remains in the most smitl 

 nearly midway between .\ntari's 

 planet crosses the meridian on the 

 the 31st at 6.9 p.m. 



Ne])tune cannot be observed ou account of his appaniii 

 proximity to the sun. 



The Stars. — About 10 p.m., at the beginning of the 

 month, Perseus and Cassiopeia will be in the north-east ; 

 Pegasus, Andromeda, Aries aud Pisces towards the east ; 

 Aquarius and Capricoruus in the south-east; Cygnus ami 

 Lyra nearly overhead; Aquila aud Sagittarius in the 

 south ; Hercules and Ophiuchus towards the south-west ; 

 Corona and Bootes in the west; and Ursa Major in the 

 north-west. 



Minima of Algol will occur on the 9th at 9.4 p.m., and 

 on the 29th at 10.47 p.m.

C. C. Mnsney. — I cannot follow your reasoning as to 

 Mr. Anderson's problem. After 1. PxB (bt-coming a 

 Queen), P to R8 (becoming a Knight;, it is just because 

 the Black Knight is unable to move that stalemate will 

 result ; sujjposing, that is, that White makes any attem].t 

 to mate.
