Look up tonight (Sept. 6) to see the Full Corn Moon glowing in the sky. If you have binoculars or a telescope, you can also see the planet Neptune glowing faintly nearby. 

The moon reached its fullest phase early this morning, at 3:02 a.m. EDT (0702 GMT), but it will still appear full to casual observers this evening. Look for it in the southern sky in the constellation of Aquarius, the Water Bearer.  

Usually, the full moon in September is known as the Harvest Moon, but this year that name is reserved for October's full moon. That's because the Harvest Moon is the full moon that falls closest to the autumnal equinox, which occurs on Sept. 22 this year. 

Now is also the best time of year to look for Neptune, which reached opposition last night (Sept. 5). This means that Neptune was directly opposite the sun in the sky, a point in the planet's orbit at which the most sunlight is reflected off its surface toward skywatchers on Earth, making it appear brighter than usual.

Even at its brightest, Neptune is just barely too dim to see with the naked eye. Binoculars or telescopes are needed to spot the distant planet in the sky, even for the most keen-eyed observers in the darkest parts of the globe. 

Skywatchers with binoculars or a small telescope can see Neptune rise with the Full Corn Moon. During the full moon's peak, at 3:02 a.m. EDT (0702 GMT) on Wednesday (Sept. 6), Neptune appeared northwest of the moon and northeast of the star Delta Aquarii, the third brightest star in Aquarius. On Wednesday night, Neptune will rise in the southeast a bit closer to Delta Aquarii.

Though Neptune may be difficult to see, you can use the moon and Delta Aquarii, the third-brightest star in Aquarius, as reference points to spot the faint planet in the sky. Neptune will rise in the southeastern sky slightly to the left of Delta Aquarii, which is located to the right of the moon.
