Venus at its Highest

Venus will be at its “greatest eastern elongation”. This is a great time to view Venus since it will be at its highest point above the horizon in the evening sky. Look for the enormously bright thing in the western sky after sunset.

Autumnal Equinox

The date (in the northern hemisphere) when night and day are nearly of the same length and Sun crosses the celestial equator (i.e., declination 0) moving southward (in the northern hemisphere).

Penumbral Lunar Eclipse

Part of the Moon will appear darker as the full Moon passes through the faint outer edge (penumbra) of the Earth’s shadow. This is the second penumbral eclipse of the year, but will treat a different region of the globe to a similar show. Sky-watchers in the Americas will miss out on this one, but it will be visible throughout much of the rest of the world including eastern Europe, eastern Africa, Asia, and western Australia.
