Check out the debris in the river (a few days after the Calgary flood), and the lightning strike on the left a few seconds into the time lapse. The Moon's reflection in the water is at 0:10 then it disappears because it gets occulted by the building. Since our perspective is different we still see the Moon!
It's not perfect and won't ever be. The next one will be better because Luca and I used improved settings. The one after will be superior still because we now know how to do HD in Time Lapse.
To shoot the Moon and the city requires two exposures - normally we shoot a static city shot before or after the Moon goes through the composite them. Shooting the river reflections requires a second camera exposing for the reflections, longer than that used for the city. So the two series were then composited into one larger one. But first, because the shots when the Moon is visible did not have an accompanying exposure for the city, the clouds "freeze". I then did some digital trickery to make the clouds move, but I can only do so much and the inconsistencies show. Oh well.
