  1. 0:00 Where is the Moon at dusk? It depends on the night: watch the same moment of twilight over two weeks.
  2. 0:04 Facing south from Georgetown at the end of civil twilight. On Mon 12 Oct a thin crescent sits 14° up in the WSW; each evening it stands higher and further east.
  3. 0:10 Past First Quarter it fattens and swings east. By Sun 25 Oct it is a Full Moon, 100% lit, only 10° up in the ENE: just risen as the Sun sets.
  4. 0:19 The Moon orbits eastward, about 12° a day against the Sun, so at the same moment of twilight it is about 12° further east each evening.
  5. 0:25 After Full Moon, look at dawn and face north. From Guyana the waning Moon passes north of overhead, 75° up in the NNE on Sun 1 Nov, then thins to a crescent 4° up in the ESE on Sun 8 Nov.
  6. 0:40 Same moment of twilight, about 12° further east each day. Predict tonight’s Moon in the lesson’s Moon lab.
