Reference, not advice

This is cultural and astronomical reference, not personal prediction or advice.

Table positions computed at 00:00 UT each day by Astronomy Engine. Retrograde flag inferred from 24-hour ecliptic longitude delta. Timeline events are found by daily scan and then bisected to one-minute precision, so station, ingress, lunation and aspect times are exact to the minute rather than to the day.
