β = ecliptic latitude (+ north, − south).
Rise and set are Local Apparent Time for the selected latitude.
Naked-eye observing uses the Sun’s altitude at the selected Monday observer time: Daylight (Sun ≥ −0.833°), Civil twilight (−0.833° to −6°), Nautical twilight (−6° to −12°), Astronomical twilight (−12° to −18°), and Night (below −18°).
Solar Glare identifies a body too close to the Sun when the sky-state rule does not already supersede its naked-eye classification.
The Sun’s observing status uses this same five-state sky classification.

ISO 2025-W11 runs from March 10 through March 16. Mercury and Venus are separated by about 1.9° in geocentric ecliptic longitude at the Monday 00:00 UTC snapshot. Jupiter is about 3.3° in ecliptic longitude from Aldebaran in Taurus.
Naked eye: 🌕 Full Moon · Sap Moon — 06:54:39 UTC. Bright moonlight favors prominent stars and planets while reducing contrast on faint deep-sky objects. Use Avior, Alsephina as the week’s fixed-sky framework.
