ephemerides

according to wikipedia:  an ephemeris (Greek ephemérios „for the day, lasting only for one day“, i.e. epí „on, at, with, while“, heméra „day“;  becomes ephemeral) stands for a table which lists the positions of a moving astronomic object. Ephemerides are in use just as much in space-craft and related  mechanics, as in many applications which relate to sun, satellites or similar, and furthermore in astrology.

ephemeris for me stands for the certain superficial view at the terrestrian hemisphere of appearances which constantly continues to beam new pictures to our own cerebrum or cerebellum for processing, which the recipient mostly classifies as ephemeral meaning not meaningful for his own being-present; collateral accompanying phenomenon so to say which I, though, do consider worth-while noticing – be it only for one day.
