β = ecliptic latitude (+ north, − south). Rise and set are Local Apparent Time for the selected latitude. Naked-eye classification becomes Daylight when the Sun is above the horizon at 21:00 LAT, and Solar Glare when the Sun is below the horizon but the body is too close to the Sun. The Sun uses glyph ☉ and text Visible.

Sky Note

ISO 2026-W41 runs from October 5 through October 11. Fixed-sky highlights include Enif — is a bright fixed-sky reference in Pegasus — uses the preserved Martz/MacRobert stick figure (4 figure paths). with representative visual magnitude 2.38. Start at the Great Square of Pegasus and work west to Enif, the only nearby 2nd-magnitude star; it sits near the lower-right corner of an imagined second square.. Mercury and Venus are separated by about 2.6° in geocentric ecliptic longitude at the Monday 00:00 UTC snapshot. Uranus is about 4.3° in ecliptic longitude from Aldebaran — is a bright fixed-sky reference in Taurus — organizes the week’s fixed-sky objects and finder geometry. with representative visual magnitude 0.87. It helps form the observer-facing Hyades / V of Taurus and Winter Hexagon / Winter Circle. Use Orion's three Belt stars as a pointer westward toward orange Aldebaran and the Hyades V. in Taurus.

Naked eye: 🌑 New Moon — 15:50:05 UTC. The dark Moon favors faint targets and extended star fields. Use Enif as the week’s fixed-sky framework.

Planets: Mercury and Venus are separated by about 2.6° in geocentric ecliptic longitude at the Monday 00:00 UTC snapshot. Uranus is about 4.3° in ecliptic longitude from Aldebaran in Taurus.

Binoculars: Favor Enif; wide fields help connect the charted geometry to the real sky.

Small telescope: Concentrate on the compact fixed-sky targets selected for the week. Increase magnification only after the target and surrounding pattern are secure. Related machine-readable descriptors include Mercury, Venus, Uranus, ecliptic longitude, Naked eye, and Binoculars.
