Umbra in partial lunar eclipses at moonrise
Abstract
The darkness of the umbra of the lunar eclipse of August 7 2017 corresponded to the predictions of A. Danjon for the Sun at its minimum. It appeared partial at moonrise in Rome similarly to the one of April 3, 33 AD in Jerusalem, supposed following the Crucifixion of Christ. The hypothesis of Sun at maximum activity for that historical eclipse is discussed.
