Google Earth Community: Where is the horizon?

Here is a really cool web application that lets you generate not only your horizon, but also current planet positions as well. It all runs in a network link so it will update automatically. There are also advanced features allowing you to set a time/date for some other day/time.

From Google Earth Blog:

One of the most frequently requested features in the last week, since Google's Sky was released, is the need to show a horizon so you can know which stars are visible from your house at the current moment. Michael Kosowsky has created an application that will generate a horizon in Sky, and it shows the position of the sun, moon and planets as well. This technically makes Sky into a "planisphere" showing your sky as it is now. The network link automatically updates to show you the planisphere for the current time. It may be a bit intimidating at first, but follow these instructions and you'll find it isn't too hard. These steps are necessary so you get the horizon for your particular location on the Earth.

1. First visit his site HeyWhatsThat.com
2. Next, check "All Panoramas" at the top and see if your location has already been calculated by looking for it on the map. Or in the list in the View menu. If your location isn't listed, simply select "New Panorama" at the top and find your location on the map. Follow the instructions to set your location and Submit request. After a couple of minutes you should get a map showing your location.
3. Now in the upper right above the map, look for View in Google Earth -> by night and select the night link. You will get a KML file taking you into Google Earth. Choose "Switch to Sky".
4. Once it loads, I recommend you click and drag the "Planisphere" network link for your location from the Temporary Places into your My Places. You can turn it on when you need it the next time you're looking at Sky. Since it is a network link it will automatically reposition the horizon and planets to their current position.
5. For further reading, here are Michael's technical notes on the planisphere feature. It shows you how to do even more with the network link. Great work Michael! I think Google should talk to you about making this a permanent feature in Sky.
