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.

Sky Notes
Kilroy: Sky Notes · generated 2026-10-22 06:56:30 UTC
ISO 2027-W07 runs from February 15 through February 21. To find Venus, first identify Sagittarius, trace the Teapot of Sagittarius, and locate Nunki in that pattern. Venus lies about 0.8° away in ecliptic longitude at the Monday 00:00 UTC snapshot; use the finder to transfer from Nunki to the planet. To find Mars, first identify Leo, trace the Sickle, and locate Regulus in that pattern. Mars lies about 2.8° away in ecliptic longitude at the Monday 00:00 UTC snapshot; use the finder to transfer from Regulus to the planet.
Naked eye: 🌕 Full Moon · Sap Moon — 23:23:39 UTC. Bright moonlight favors prominent stars and planets while reducing contrast on faint deep-sky objects. Use Adhara, Wezen as the week’s fixed-sky framework.
