When people hear about the Harvest Moon, they typically associate it with the full moon in September. However, every third year, the Harvest Moon shines in October’s sky.

This is one of those years, meaning September’s full moon is referred to as the Corn Moon.

The month that carries the title ‘Harvest Moon’ is determined by how near its full moon is to the autumn equinox. This year, the equinox is on September 22. With October’s full moon falling on October 6, it is nearer to the equinox than September’s full moon, which happens on Sunday, September 7.

The Corn Moon peaks in illumination Sunday afternoon, before it rises overhead. But it’ll still appear full and bright on Sunday evening.

Meanwhile, on the other side of the world, Asia will have the chance to enjoy the year’s second total lunar eclipse.

This weekend, Earth will cast its shadow on the full moon as our planet aligns perfectly between the moon and the sun. The total eclipse will last an impressive one hour and 22 minutes, with the entire celestial event — beginning from the first shadow cast on the moon — extending over five hours.

The shorter lunar eclipse in March was perfectly positioned for viewers in the Americas. However, the upcoming event — known as a blood moon due to its reddish color — will appear on the opposite side of the globe for Sunday night and early Monday, local time.

The entire eclipse will be observable across Asia, from Saudi Arabia to the Philippines, reaching as far north as the Arctic Ocean and all the way down to Antarctica. Portions of East Africa and the western part of Australia will also get the full experience. Meanwhile, the rest of Africa and Australia, along with Europe, will see parts of the eclipse. Some glimpses will also be possible from the Brazilian coast and parts of Alaska.
