Abstract: Eclipse curves of Ca H, K, and Hε structures are obtained from the 1958 flash spectrum. Under the active region, Ca and Hε lines are enhanced by 0.2 and 0.3 in logarithmic scale, respectively. Ca line ratio K/H is greater than 1 and seems not to reach 2. 58% of Ca line profiles below 2500 km do not show central dips but single peaks. Width difference of Ca and Hε lines may give kinetic temperature of 9000circ K for isolated structures.
