When the Moon Masks the Sun's Face 



Only during the fleeting minutes of a total eclipse 

 may the Sun's weirdly beautiful Corona be seen. 

 It is a pearly wliite glow, like a halo, which extends 

 in an irregular outline millions of miles into space. 

 Photographs will be made of the Corona, as usual. 

 to determine its uize and outline, which variea a 



great deal from one eclipse to another and appears 

 to be related to the frequency of the sunspots. 

 It is hoju'd also to obtain good cinematograph pic- 

 tures of the total solar eclipse on June 8, lQ18,and 

 many problems hitherto not accurately determined 

 are cxiK'cted to receive clarification at this time.
