Specify Observer Location:
You can specify a topocentric observer location
by choosing from a list of major world cities,
by choosing from a list of world-wide observatories, or
by giving the latitude, longitude, and altitude.
Please select from from the following list:
Lookup Named Location
Use observatory code numbers (if you know them) or names.
For example, enter "675" to select the Palomar Mountain main site.
Or, enter "palomar" for a list of matching sites.
Choose from a List
Specify Observer Coordinates
Longitude and Latitude can be entered as either
"degrees minutes seconds" or decimal degrees.
In either case, they should alway be positive and use the appropriate
East/West and North/South selections.
If entering "degrees minutes seconds" use spaces or commas between elements.
If Altitude is unknown, zero can be used for optical sites without much loss of accuracy.
