Conclusions

At the 7 March, 1970 total eclipse, there were no significant differences between intensity levels between K-line and H-line, nor were there any finely structured features in the upper atmosphere of the sun in Hα larger than 2.5″. The two Hα features close to the limb, though unexpected, do not appear to be remarkable.
