The wheel below shows the entire sky that is visible from Fairfield (change location), and shows the path of TANDEM-X across the sky at 12:36 EST on 17 January 2022. Change the limiting magnitude to see more or fewer stars.

By clicking and dragging the wheel below, you can turn it to place different green compass points at the bottom. The stars at the bottom of the wheel will then match the ones you will find above the horizon in that direction.
