Observing opportunity for HELIOS 1B

by Dominic Ford

The wheel below shows the entire sky that is visible from Ashburn (change location), and shows the path of HELIOS 1B across the sky at 15:05 EDT on 21 October 2021. 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.
