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 2027-W15 runs from April 12 through April 18. Mercury and Neptune are separated by about 0.4° in geocentric ecliptic longitude at the Monday 00:00 UTC snapshot.
Naked eye: 🌓 First Quarter — 22:56:39 UTC. Moderate moonlight makes timing and local sky position important for faint targets. Use Algieba as the week’s fixed-sky framework.
