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-W29 runs from July 19 through July 25. Uranus is about 1.2° in ecliptic longitude from Aldebaran in Taurus. To find Jupiter, first identify Leo, trace the Sickle, and locate Regulus in that pattern. Jupiter lies about 1.3° away in ecliptic longitude at the Monday 00:00 UTC snapshot; use the finder to transfer from Regulus to the planet.
Naked eye: No principal lunar phase is listed this week. Check the Moon's position each night and favor darker hours for low-contrast targets. Use Sabik, Rasalgethi as the week’s fixed-sky framework.
