This week, skywatchers have another chance to see a supermoon, which occurs when the moon is full and its orbit is closest to Earth.
Skies will be clear Tuesday and Wednesday evening, according to the National Weather Service in Seattle.
At 221,994 miles away, the moon will be closest to Earth this year just hours before reaching its fullest phase Wednesday at 11:37 a.m. PDT, according to EarthSky.
Although the full moon theoretically lasts only an instant, that moment is imperceptible to ordinary observation, according to Space.com, and for about a day before and after it will appear full.
This near-full moon will be visible all night Tuesday and Wednesday. It won’t necessarily look bigger, according to EarthSky, but may look brighter.
Look for it in Seattle and the Puget Sound area at 8:55 p.m. Tuesday and 9:50 p.m. Wednesday. It will be highest in the sky around midnight.
The July Full Moon has three nicknames: “Full Buck Moon” for the velvety antlers that male deer grow in the spring, “Full Hay Moon” for the high summer hay, and “Full Thunder Moon” for the thunder that is frequent. in July, according to farmers. ‘ Almanac.
While the position of the moon’s orbit makes this full moon particularly special, any full moon can have a powerful effect on sleep, according to a 2021 study by a team of scientists including Professor Horacio de la Iglesia de l University of Washington.
The study found that in the days leading up to the full moon, people fall asleep later and sleep less.
The team confirmed that the evenings before the full moon — when participants slept the least and went to bed the latest — have more natural light available after dusk, according to a UW press release. The waxing moon gets brighter as it progresses towards the full moon and usually rises in the late afternoon or early evening, setting it high in the sky after sunset.
The second half of the full moon phase and waning moons also give off significant light, but in the middle of the night, since the moon rises so late in the evening at these points in the lunar cycle.
“We hypothesize that the patterns we observed are an innate adaptation that allowed our ancestors to take advantage of this natural source of evening light that occurred at a specific time in the lunar cycle,” said the lunar. lead author Leandro Casiraghi, UW postdoctoral fellow at the department. of biology, said in the press release.
