XLII. Stars of the Chautauqua Summer Sky 



The following is a suggestive list of the conspicuous stars 

 and constellations which appear in the Chautauqua summer 

 sky. The positions designated are for nine o'clock on the eve- 

 ning of July seventh; however, the daily change in the posi- 

 tions is so slight that the list is applicable to any part of the 

 mid-summer season. The stars rise about four minutes 

 earlier each evening; four minutes of time corresponds roughly 

 to one degree of space measured on the arc of the sky. Thus 

 the whole sky apparently shifts about one degree westward 

 every twenty-four hours. The quarterly divisions refer to 

 the four quarters of the heavens, as the observer looks di- 

 rectly up into the dome, i.e. the east of a map becomes west, 

 and west becomes east. The list is given merely to suggest 

 the large possibilities and interest of star-study, and only the 

 most conspicuous bodies are enumerated. For further in- 

 formation see Serviss, Round the Year with the Stars, and 

 Olcutt, Field Book of the Star.
