ISS Trails

Couple of weeks back I spotted the ISS but I was not well equipped to capture a trail against the "Fixed" stars. On 3rd Jan me and  Joy wanted to capture it from roof. It was evening time but ISS was relatively fainter and lower in the horizon. Also the sky was almost covered by  cloud. Following tables ( taken from have all the details

I tried to click the trail with 20 and 25 second exposure but sky was too bright to distinguish the trail.

Another one is here. The trail is very faint but next time I will try to spot it in the morning.
