Astronomy in September 2018

With dark skies back and the good weather holding, there may even be some cloudless
night skies to enjoy. Here are some suggestions for things to look out for in September.
There are some good photo opportunities this month.

First week of Sept (after sunset) - Mars, Saturn and Jupiter can be seen in the south and west.

7 Sept - Neptune at Opposition. The blue giant planet will be at its closest approach
to Earth and its face will be fully illuminated by the Sun. It will be brighter than
any other time of the year and will be visible all night long. This is the best time
to view and photograph Neptune. Due to its extreme distance from Earth, it will
only appear as a tiny blue dot in all but the most powerful telescopes.

8 Sept - Mercury below a thin crescent Moon. View before sunrise.

9 Sept - New Moon. The Moon will located on the same side of the Earth as the
Sun and will not be visible in the night sky. A good time to observe faint objects
such as galaxies and star clusters.

17 Sept (early evening) - Saturn can be seen below a first quarter Moon in the early evening

18 Sept (evening) - Mars can be seen to the lower left of a waxing gibbous Moon

23 Sept - September Equinox. The Sun will shine directly on the equator and there
will be nearly equal amounts of day and night throughout the world. This is also
the first day of Autumn (autumnal equinox) in the Northern Hemisphere.

25 Sept - Full Moon. The Moon will be located on the opposite side of the Earth
as the Sun and its face will be will be fully illuminated. This moon is also known as
the Harvest Moon which is the full moon that occurs closest to the September
equinox each year.

25 Sept - Venus at greatest brightness

29 Sept - (late evening) The Moon can be seen amongst the Hyades cluster
