![]() The ecliptic is the path that the Sun–and, roughly speaking, the Moon–follow across the sky.Īnother way to think about this is to think about the direction of Earth’s tilt. Sleep, crime, and menstruation: how Full Moons affect humans The Moon’s Shallow AngleĪstronomers explain this Harvest Moon phenomenon by noting that, on September evenings, the ecliptic makes a shallow angle with the horizon in the Northern Hemisphere. This is because the Full Moon rises at sunset, and refraction causes more of the red sunlight to come through at that time, giving the Moon a red tint. The Harvest Moon may look red when it rises. Historically, the extra moonlight meant that farmers could work and harvest their crops for a longer time in the evenings. With successive moonrises coming around the same time of day, it may feel like there are several Full Moons in a row. At the lower latitude of New York in the USA, the difference is around 25 minutes per day. At the latitude of Edinburgh in the UK, the Moon rises about 10 minutes later each day. In the Northern Hemisphere around the Harvest Moon, however, the difference in the time of moonrise from one day to the next is less than 50 minutes. On average, the Moon rises about 50 minutes later each day. There is also an astronomical reason why the Full Moon closest to the autumnal equinox is called the Harvest Moon. And, true enough, the Harvest Moon graces the skies in the harvest season in the Northern Hemisphere. Usually, Full Moon names reflect the time of year they happen. Change location Why Is It Called the Harvest Moon? Times and dates are based on the local time in Odesa. Times for the Harvest Moon vary by time zone. The Harvest Moon is the Full Moon nearest the autumnal (fall) equinox, which happens around September 22, depending on the year and time zone. ©/petesphotography When Is the Harvest Moon?

And for those who live even farther to the north, a paradox: the moon appears to rise earlier! At Reykjavik, Iceland (latitude 64.2ºN), for instance, the times of moonrise on Sept. ![]() Interestingly, for those who live near 60º north latitude, the moon does indeed appear to rise at the same time each night around the time of the Harvest Moon. At Melbourne, Australia, for instance, the night-to-night difference amounts to 72 minutes. ![]() As such, the difference for the time of moonrise exceeds the average of 50 minutes per night. In contrast, for those living in the Southern Hemisphere, the ecliptic at this time of year appears to stand almost perpendicular (at nearly a right angle) to the eastern horizon. The reason for this seasonal circumstance is that the moon appears to move along the ecliptic and at this time of year when rising, the ecliptic makes its smallest angle with respect to the horizon for those living in the Northern Hemisphere. Meanwhile, the difference is less at more northerly locations (at Edmonton, Alberta, located at latitude 53.6ºN, the average difference is only 12 minutes). A quick study of the table shows that the night-to-night difference is greatest for the more southerly locations (Miami, located at near latitude 26ºN., sees moonrise come an average of just under 36 minutes later). In actuality, over this three-night interval for our relatively small sampling, the rising of the moon comes, on average, just over 25 minutes later each night - or exactly one-half of the normal 50 minutes. ![]() Harvest Full Moon: Moonrise times Location ![]()
