Maps of Solar Eclipses from 1945 to 1949

In the midst of revolutionary turmoil, the Tsingtao Observatory published this document containing tables and maps for the annular eclipse of May 9, 1948. The content of this bulletin is in both Chinese and English.

Although ancient Chinese manuscripts contain many of the very oldest records of solar eclipses, the development of Asian eclipse maps seems to have arrived only in the 20th century.

This Chinese eclipse map contains three sets of isolines; isomagnitudes for the eclipse and isochrons for the begin and end of the partial phases of the eclipse. The path of the annular eclipse can be seen sweeping across southeastern China and past Korea. An interesting feature of this map is that all three sets of isolines end abruptly at the Chinese frontier.
