Finding Orion in Southern Hemisphere - Tips for Locating Orion from Sidney in Southern Hemisphere

12 February 2008 No Comment

Are you watching the night sky from Australia, Chile, South Africa or other countries in southern hemisphere? If ye, you probably find the pictures of HomeboyAstronomy tips weird. The reason is that the sky looks different from your location compared to our location here in north. It looks like your sky, or our sky, is just upside down. We noticed some time ago that our articles serve only the astronomers in northern hemisphere, not those who are located in southern hemisphere. Therefore we are now starting a new era in HomeboyAstronomy by bringing in tips for astronomers of southern hemisphere. We start from the basics by describing how you can find constellation Orion when you are located in southern hemisphere.

Constellation Orion seen from Sidney Australia one hour after sun set in February 2008Let us assume the observer is located in Sidney in Australia. The observer is willing to watch one of the most interesting constellations, Orion, the hunter. The observer is going to watch Orion right now, in mid-February. We decided to run a simulation for this, and in the simulation the observer is watching Orion about one hour after sun set. At this time Orion is in highest position in the sky of Sidney.

Look at the figure on left side. In the figure you see constellation Orion located in direction north. Notice that for those who observe Orion from northern hemisphere Orion seems to be upside down. This simply is caused by the round shape of our planet. In order to simulate this in northern hemisphere, simply stand on your head and watch Orion. It looks like that in Australia.

If you are located in same latitude as Sidney in southern hemisphere, go out one hour after sun set and watch towards North. Your sky should look just like in the picture on left. You should easily see the belt of Orion (three stars in line) and the brightest stars of the constellation (Betelgeuze and Rigel). If you keep on watching Orion for few hours, you should see how it starts going to down left until it finally goes under horizon in direction west. This happens about three hours before sun rise.

Notice that the sky looks like this in Sidney and other cities of the same latitude only right now in February. As the time goes on, the location of the stars change every day, as it was discussed in my article Do The Stars Move? - An Easy Method to Notice How the Stars Move on Night Sky. After half a year you cannot see Orion in this same location as shown in the image.
