Observing opportunity for SL-3 R/B
The wheel below shows the entire sky that is visible from Ashburn (change location), and shows the path of SL-3 R/B across the sky at 19:23 EDT on 27 July 2020. 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.
