Computed by us from JPL's DE440 planetary ephemeris with Skyfield: phases, positions, magnitudes (Mallama & Hilton), separations, equinoxes and solstices. Full Moon names are the traditional North American ones. Meteor showers: International Meteor Organization. Eclipses: Fred Espenak, NASA GSFC. Planet times ignore hills and buildings; a planet 5° up needs a clear, low horizon.
