Harvest Moon lights evenings all week
According to folklore, the Harvest Moon gets its name from the light it provided farmers to bring in their crops into the early evening as days grow shorter.Posted — Updated
Each of the 12-13 full Moons throughout the year has a name, often several. Many have their roots in Native American names and reflect what tribes were doing at the time – hunting, fishing or with their crops. According to folklore, the Harvest Moon gets its name from the light it provided farmers to bring in their crops into the early evening as days grow shorter.
But that is true of any full Moon, which rises around sunset and shines brightly until sunrise. What sets the Harvest Moon (Monday 7:30 p.m.) apart is that it is the full Moon occurring closest to the September Equinox (Wednesday, 2:41 p.m. ET).
The Moon, like the Sun, takes its lowest path through the sky around this time of year, and the brightness of the full, or nearly full, Moon rising so soon after sunset, never lets the sky to get really dark. So, work can continue, at least that's how the story goes.
Big, bright Moon this week
You may also notice the Moon seems a bit bigger this week for an hour or so after moonrise. The reason for this is a combination of the season and how our brains work.
NASA astronauts disagree with this explanation saying that they've also experienced the Moon illusion from space, with nothing in the foreground to compare the Moon to. The Moon still looks bigger to them.
The Moon will also appear to be a yellow-orange color as it rises. This is normal as the moonlight passes through more atmosphere near the horizon, scattering more of the blue light and letting more red light through. Smoke from wildfires on the west coast also enhance this effect making the Moon look even more red.
