This information is intended for the non-astronomer who wants to identify what they are seeing when they look at the sky.
The first thing to do is get acquainted with what the night sky looks like. Here is a chart of the sky over Armagh right now.
The above chart is from the excellent Heavens Above site which is also used for the satellite data on this page.
The National Schools Observatory web site has very good horizon views of the sky for the current night.
Another horizon view is available from Fourmilab.
Some notes on tonight's sky are available from Earth and Sky.
You can obtain images of any part of the sky from SkyView, the Internet's Virtual Telescope.
The Night Skies Network shows live views of the night sky from amateur astronomers.
Up to date news about astronomical events can be obtained from;
The appearance of the sky changes according to time and place and everything on this page assumes Armagh as its location. You should customise it to reflect your own location. With this chart you should be able to quickly identify if what you are seeing is a bright planet such as Venus, Jupiter, Saturn or Mars.
A view of the horizon in the early evening may make things clearer.
The Heavens Above site has daily predictions for all of the brightest satellites.
The Aurora Australialis are the Southern Lights which are visible in the southern hemisphere.
Formed when thin cloud passes in front of the Moon, or other bright object. The small droplets of water in the cloud diffract the rays of light from the Moon en route to the observer's eyes. The size of the water droplets can be determined from the radii of the coloured coronae, with the smallest droplets producing the largest coronae. Coronae can be up to 5 or more degrees (10 or more lunar diameters) in radius.
