THE GUIDE TO NATURE 



The Heavens in September 



BY PROFESSOR ERIC DOOLITTLE, OF THE 

 UNIVERSITY OF PENNSYLVANIA. 



With the arrival of September, the 

 first of our autumn months, the faint 

 summer constellations already begin 

 to disappear. The very large Virgo 

 (which, however, is more properly a 



taken for one of the brighter planets, 

 is now low in the west, while the bright 

 Leo below it has completely dis- 

 appeared. The last two groups of the 

 summer train of stars are the faint but 

 interesting Capricornus and Aquarius, 

 and these are nightly coming into 

 more favorable position in the 



NORTH

 below the ground in the west, while the 

 interesting stars of the Balance and 

 the striking Scorpio have partly with- 

 drawn from our evening sky. 



The magnificent Arcturus, that enor- 

 mous, reddish sun, which shines so 

 brightly that it might easily be mis- 



south. The slow changing of the 

 sphere has this month brought +he 

 beautiful Fomalhaut, the Solitary One, 

 into our evening sky, and overhead the 

 wonderful blue Vega and all the bril- 

 liant groups along the Milky \Vay 

 shine out in excellent position for ob- 

 servation and study.
