Promontorium Heraclides - 11.2.2022 at 21.18 Harjavalta Observation number 104555

Visibility IV / V

Hakala Raimo's observation inspired me to examine my mobile rapids from the Moon in the evening of 11.02. Prom. Heraclides was illuminated with the environment overshadowed. In Jean-Dominique Cassini’s monthly map from 1679, the promontory is clearly depicted as a female figure, and I don’t remember seeing the maiden as tender as that night, the picture really doesn’t do her justice! Cassini had married Genevieve de Laistre in 1673, and some scholars consider it possible that Moon Maiden is an astronomer in recognition of his wife's love.
