- First image from immediately after sunrise, at 8:03am, last image at 8:40. 
- Official sunrise (Dec.24): 7:53am
- I predict good direct light through that window until at least 10 am. 
- Slightly cloudy, so sunlight was a bit diffuse.
- Apologies for bad focus.
- Last three images taken with stairwell light on.
- Last two images taken with room light on (single lightbulb positioned above and behind me).
- Exposure of first image 1/4 sec at f/3.5.
- Exposure of last image: 1/15 sec at f/2.8.
