Step 1: Heavens Above

Heavens-above.com is an easy-to-use website that tracks visible space objects like satellites and comets. It is important to enter your location since your position on earth effects when and where the object is visible to you. It doesn't need to be precise, so can select the largest city near you. Since the station's orbit is inclined about 52 degree, you must be within the latitude range of -52 to 52 degrees to see it, which luckily is most of us.

Step 2: When and Where?

Once you have your location entered, it is time to see when and where the station will pass.  With any luck, you will have one (or more) passes tonight and the weather cooperates. There can be periods where there are no visible passes for a week.

The table give you the basic information of where and when to see the pass. For this pass you will need to face North and look for it to pass West to East in an arc that reaches 35 degrees above the horizon. For a more detailed view, which may be helpful on your first sighting, click on the date.
