Challenging
It might be tricky. Clouds, twilight, or a low path could make the station harder to spot.
Viewing tips
From Ontario: Twilight is short here, so be ready at the start time as the sky darkens and lightens quickly. Look for it to appear in the SW and travel towards the ENE.
Cloud cover is high (100%), so the station will likely be hidden behind clouds.
Conditions are evaluated using cloud cover, moon phase, and Tiangong elevation.
