When one conveys certain things, particularly of such gravity, should one not then appropriately cite sources, authorities...
QuoteIt's a busy skywatching month ahead. The first full week of October sees two top-notch skywatching events, with Saturn reaching opposition, and the Moon occulting Jupiter for North America on October 6th.
This month's occultation of Jupiter by the Moon is one of the best-placed and top skywatching events for 2026. The event transpires in the early morning hours of Tuesday, October 6th, centered on 10:16 Universal Time/6:16 AM Eastern Time (EDT). The Moon is a -20% illuminated waning crescent when it covers up Jupiter, meaning the daytime illuminated side of the Moon will lead the way when Jupiter ingresses behind the Moon, and will reappear from behind the Moon's dark limb.

Next up, Saturn reaches opposition for 2026 on October 4th. Falling near last month's equinox, this puts Saturn in the rare position of straying just into the corner of the non-zodiacal constellation Cetus the Whale.
The current tilt of the rings of Saturn are 12 degrees wide in late 2026, widening from edge-on in 2025. The rings will again reach their widest tilt in 2031. Saturn is always a sight to behold at the eyepiece, even in a small telescope.
It's worth watching for enigmatic spokes on Saturn's rings as we come off of last year's equinox season for the planet. These disruptions look like radial streaks across the plane of the rings, and are a thought to be due to meteoroid impacts.
An intriguing effect to watch for near opposition is what's known as the Seeliger Effect, or opposition surge. This is a retro-reflector type phenomenon, as the planet reaches 100% illuminated phase versus the viewing angle. The Moon near Full experiences something similar, as it reaches up to a half dozen times as bright (over 2 full magnitudes) as the 50% illuminated 1st or Last Quarter phase Moon. All those little shadows (or lack thereof) do indeed add up.
