海王星衝Neptune at Opposition
海王星距地球最近、整夜可見,需望遠鏡觀測,呈現淡藍色小圓盤。Neptune is closest and visible all night; a telescope shows a tiny pale-blue disc.
流星雨極大期、日月食、行星衝與二分二至,附倒數提醒。日期以台灣時間為準。Meteor shower peaks, eclipses, planetary oppositions and solstices — with countdowns. Dates in Taiwan time.

土星距地球最近、最亮,整夜可見;衝日前後幾天環會因「衝效應」明顯變亮。Saturn is at its brightest and closest, visible all night; the rings brighten from the opposition surge.
天王星整夜可見,雙筒望遠鏡即可辨認,呈淡綠色星點。Uranus is visible all night; binoculars reveal a faint greenish point.
火星距地球最近、最亮,是拍攝火星表面細節的最佳時機,約每 26 個月一次。Mars is closest and brightest — the best window for surface detail, once every ~26 months.
木星整夜可見、視直徑最大,大紅斑與四大衛星是入門觀測的首選目標。Jupiter is visible all night at maximum size; the Great Red Spot and Galilean moons are classic targets.
土星整夜可見;土星環傾角逐年變化,值得逐年比較。Saturn visible all night; the ring tilt changes year on year and is worth comparing.
事件日期取自公開天文年曆並以台灣時區整理;流星雨極大期可能前後一天,實際觀測請搭配「天氣觀測」確認雲量與月相。 Dates compiled from public astronomical almanacs in Taiwan time; meteor peaks may shift by a day. Check the Weather page for cloud cover and Moon phase before heading out.
