Taking R = 976"'80, r 31"'42, at Ingress, and R = 976"-82, 

 r = 31"'42, at Egress, and mean solar parallax = 8"'950 X fl + ), 

 we have 



For 2nd phenomenon, " Apparently Geometrical Contact" 



+ 4"-8i = +o"-2i52 n +-6020 8 E.A. 7577 8 N.P.D. o"- 



and for 8th phenomenon, " Black drop assumed a solid appearance "
