The photo above is a blend of several images captured during a time lapse sequence of the full harvest Moon rising on September 8, 2014. In the early autumn the harvest Moon rises with only about 20-25 minutes difference on successive evenings as opposed to about 50 minutes difference most other nights. This is a result of the shallow inclination of the lunar orbit to the horizon at the time of the autumnal equinox. Note that near the time of the vernal equinox, the full Moon rises about 90 minutes later on successive nights due to a steeper inclination. However, when the full Moon sets (morning) in early spring the interval between successive sets is the same as during evening rises in the autumn.
The water in the foreground is the Erie Canal in New York at Lock 32 (the structure in the foreground). Though the Erie Canal had a major economic impact on the young nation when it opened to commercial traffic in 1825, today it's largely a recreational waterway.
