ECLIPSE OBSERVATIONS. 261 



162°. A group of three brilliant prominences near south pole; 

 to positions of centers of these prominences about 165°, 



182° 172°. 5, and 179°. 5 (position of south pole of sun i6y°.4). 

 Very bright coronal matter over the group. Strong hood 

 or arch over the first two prominences ; part of an arch over 

 the third (named in order of increasing P. A.). 



186° A large bright " petal " of coronal matter over the brilliant 

 to flame-like prominence in position angle 205°. A closely 



226° packed series of arches, all of the pointed or ogival type, 

 except possibly the inner one. At least six of these arches 

 stand out distinctly. The highest ones very sharply 

 pointed, and the apexes, with increasing height, are to one 

 side of the center of the prominence, as though the dis- 

 placement were an effect of perspective. 



231° Another large brilliant "petal" of coronal matter, with the 

 to great eruptive prominence centrally in its base (P. A. of 



270° center of prominence about 251°). At least five arches are 

 visible. In this instance the arches are oval curves, and not 

 pointed at the vertices. The arches are somewhat skewed, 

 the inclination being in the same direction as the trunk of 

 the great skeleton prominence they enclose. A comparison 

 of the Lick and Lowell plates shows marked changes in 

 the eruptive prominence. 



233° -5 Base of the " rocket " prominence. 



The higher part of the trajectory of this eruptive forma- 

 tion or jet is not certainly shown on the Lick plates taken 

 about 27™ earlier. On the Lowell plates the upper part 

 of the curve is clearly shown and the brilliant nucleous has 

 apparently passed its greatest height and is descending. 



270° Very brilliant " petal " of coronal matter, with large bril- 



to liant prominence centrally (P. A. of base of prominence 



320° extends from 288° to 301°). Complex detail above the
