Cloud-hampered ISS pass of January 2nd, and deep twilight pass of January 3rd

The evening of January 2nd started clear, so I set up the video to film another pass (17:01 UTC) of the International Space Station (ISS) which currently has the Dutch astronaut André Kuipers on board.

Unfortunately, an episode with many clouds commenced just before the pass. I managed to film glimpses of the ISS through gaps in the cloud cover.

Very frustratingly, it was completely clear again 10 minutes after the pass.

On January 3rd, it was clear. ISS made a pass in very deep twilight (16:04 UTC), with the sun at an altitude of only -3.5 degrees! Nevertheless, the ISS was well visible by the naked eye, in a bright blue sky with no stars yet.
