Abstract

The Partial Lunar Eclipse of September 14.—Prof. C. D. Perrine, director of the Cordoba Observatory, sends a note on the final phase of this eclipse. He states that the departing shadow was dark greyish, almost black, and that it was considerably broader than the amount to be expected at the time, which was, however, not accurately noted. Its sharpness recalled a partial solar eclipse. He thinks that it was from fifty to a hundred miles broader than the computed value, and asks what the appearance was to those who saw the maximum phase of the eclipse. This was observed by the writer of this note, and there was an unmistakable sunlit rim at the moon's north limb; it was not measured, but agreed roughly with the predicted amount.
