"Fred Espenak, astronomy's 'Mr. Eclipse', dies at 71" by @Spacecom - He was the one behind the NASA Eclipse Page and later in retirement kept #eclipse data up-to-date with his Mr Eclipse atlas that computed #SolarEclipse and #LunarEclipse data through the upcoming century. I used his data for every lunar and solar eclipse I've watched. I would have liked to meet him. #astronomy
