Venus at Superior Conjunction

Crescent Venus
Venus approaching inferior conjunction, 24Dec2013

Today Venus is passing through superior conjunction, passing behind the Sun as seen from our earthbound point of view.

Venus will reappear in the sunset in mid-September, a brilliant star like object low on the horizon, just above the glow of sunset.

When Venus does reappear we can expect a few UFO reports by people unfamiliar with the normal workings of our skies. In late 2018, when it last emerged in the dawn we had a few such reports here on the island, including a very nice video and folks who could not accept the fact that the “strange light” was simply a bright planet.

Venus will spend the remainder of 2019 in the evening sky, reaching maximum elongation on March 24th, 2020.

This is a modest apparition, with the planet only 19° from the Sun.

This evening will feature a a pretty set of planets and the Moon low in the sunset. Mercury, Mars, and a thin crescent Moon will be visible above the glow of the setting Sun.

The Moon will be a very thin sliver, a mere 4% illuminated. Look 7° above the Moon for Mars. Mercury will be harder to spot, about
7° below the Moon, closer to the sunset and a little north (to the right).

This evening, April 8th will offer a beautiful view with Mars and slim crescent Moon located between the Pleiades and the larger Hyades star clusters.

The Moon will be a slim crescent, only 14% illuminated. Mars will be 5° north (to the right) of the Moon, shining at +1.5 magnitude. Above and below will be the bright star clusters.

Mars and the Pleiades

Over the next week Mars will pass by the Pleiades star cluster. The bright planet and the cluster should make a pretty arrangement in the evening sky.
