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 2026-W28 runs from July 6 through July 12. Mars and Uranus are separated by about 1.1° in geocentric ecliptic longitude at the Monday 00:00 UTC snapshot. To find Venus, first identify Leo, trace the Sickle, and locate Regulus in that pattern. Venus lies about 4.0° away in ecliptic longitude at the Monday 00:00 UTC snapshot; use the finder to transfer from Regulus to the planet.

Naked eye: 🌗 Last Quarter — 19:28:59 UTC. Moderate moonlight makes timing and local sky position important for faint targets. Use Dschubba, Acrab as the week’s fixed-sky framework.
