The celestial bodies are gathering for an event this weekend, and Portland’s clouds may block it from view.
Monday evening, Monday morning, from 29 to 30 November there will be a lunar eclipse of penumbra. According to NASA, it will gradually darken the face of the moon for more than four hours. This will be the second lunar eclipse in Oregon this year, following a previous penumbral eclipse in July.
A lunar eclipse occurs when the Earth’s shadow falls on the moon and only occurs on a full moon when the sun, earth and moon come together. Since only the lightest outer shadow of the Earth (called penumbra) obscures the Moon, a penumbral eclipse is subtler than a full or partial eclipse.
During a penumbral lunar eclipse, the moon gradually becomes slightly darker up to the maximum eclipse, after which it gradually brightens again. Unlike a full or partial eclipse, the face of the moon is not completely dark and some people may not notice a difference.
The eclipse is expected to start at 23:32 on Sunday, reach an eclipse maximum at 1:42 on Saturday, and end at 3:53 on timeanddate.com.
Whether or not we can actually see it in the Portland area depends on the cloud cover. Daytime skies are expected to be clear on Sunday, with clouds expected to roll over at night, the National Weather Service said.
Two more lunar eclipses will be visible in the Pacific Northwest over the next two years. A total lunar eclipse is about to occur on May 26, 2021, early in the morning, and a partial lunar eclipse from November 18-19, 2021 Everyone knows in the United States.
Jim Todd, OMSI’s director of space science education, said a solar eclipse always occurs two weeks before or after a lunar eclipse, but this time most parts of the world will miss it – the next solar eclipse. total will be December 14 in Chile and Argentina. Only visible from some areas. A partial solar eclipse can be seen in parts of South America, southwestern Africa, and Antarctica.
The Pacific Northwest will not see another eclipse until the annual solar eclipse of October 14, 2023 and the total solar eclipse of April 8, 2024.
