This week’s sky highlights Saturn approaching its October 3 opposition, featuring the Seeliger effect brightening its rings, while Neptune reaches opposition on September 26. The full Moon rises that night, with Saturn just below; the waning Moon later guides observers to the Pleiades on September 30. Algol dims on September 27 and October 2. Vega dominates the west, Cassiopeia climbs high in the northeast, and globular clusters remain visible as summer ends. By dawn, Mars and bright Jupiter appear in the east, with Venus low in the sunset. Uranus and Neptune require telescopes for viewing this week. https://skyandtelescope.org/astronomy-news/observing-news/this-weeks-sky-at-a-glance-september-25-october-2/
