Location Help

SkySafari needs to know your location on Earth in order to correctly plot the location of objects in the sky. You can set this in the Location view from the main Settings screen. Four pieces of information are necessary:

• Latitude - distance north or south of the equator
• Longitude - distance east or west of the prime meridian
• Elevation - altitude above sea level
• Time Zone - local time offset in hours from Universal Time (UT)

A time zone west of (behind) Universal Time is negative; time zones east (ahead) of UT are positive. Always enter the time zone offset for Standard Time only. SkySafari will automatically correct for Daylight Saving Time.

Use Current Location

Tap the "Use Current Location" button to automatically determine your location from your iPhone's Location Manager, your Android device's GPS, or other information supplied by your internet service.

Choose Location From Map

If your mobile device is connected to the internet, you can use Apple or Google maps to choose a new location. This is useful if you want to see the sky from a place other than where you are located right now.

Choose Location From List

If your mobile device is not connected to the internet, you can choose a location from a searchable list of thousands of cities in SkySafari's database. The location database in SkySafari's basic version includes every city worldwide with more than 100,000 inhabitants. In SkySafari Plus and Pro, the location database includes all cities with more than 10,000 people, plus more than 500 observatories, star parties, and NASA centers.
