Graphic ephemeris December 2021

Plot daily planetary longitudes through a month and inspect the same positions in a table.

Each dot is one computed daily table position at 00:00 UTC. Lines only connect those samples; a crossing is not a calculated conjunction time or a forecast.

Swiss Ephemeris positions, viewed from Earth in the tropical zodiac, rounded to 0.01°. Each row is sampled at 00:00 UTC. Selected dates were checked against JPL reference positions; this does not certify every day in the 2020–2035 dataset. No position or event time is calculated between samples.
