A passenger plane flying above Changi Business Park was dwarfed by the moon last night, a day after Thursday's harvest moon.
A harvest moon in the Northern Hemisphere is the full moon that appears closest to the autumn equinox, which usually falls around Sept 22.
In some traditions, farmers see this as a sign that their crops are ready to be harvested.
Usually, the harvest moon occurs in September. But, depending on the timing of the equinox and the regular lunar cycle, the first full moon closest to the equinox can sometimes be in October, as happened this year.
The phenomenon is not really that rare. The last time a harvest moon occurred in October was in 2009, and the next one is due in three years.
