The next full moon of 2019 is the Hunter’s Moon, which will happen this weekend. It will soon be followed by the peak of October’s third meteor shower, the Orionids.
The Hunter’s Moon will officially reach its full phase at 5:17 p.m. Sunday, Oct. 13. According to NASA full moon will appear full for about three days around then.
When it actually rises at 6:46 p.m., it could make it appear larger and more orange than usual, an illusion caused by the horizon at sunset.
According to Earthsky “If you’re in the Northern Hemisphere, look for the moon to be bright and full-looking for several nights beginning around October 11 and 12. Keep watching on October 13 and 14. Around all of these nights, you’ll see a bright round moon in your sky, rising around the time of sunset, highest in the middle of the night”.
Earthsky mentions “The orange color of a moon near the horizon is a true physical effect. It stems from the fact that, when you look toward the horizon, you’re looking through a greater thickness of Earth’s atmosphere than when you gaze up and overhead. The atmosphere scatters blue light – that’s why the sky looks blue. The greater thickness of atmosphere in the direction of a horizon scatters blue light most effectively, but it lets red light pass through to your eyes. So a full moon near the horizon – any full moon near the horizon – takes on a yellow or orange or reddish hue”.
