This Sunday’s supermoon eclipse marks the first time in three decades that a supermoon will occur at the same time as a lunar eclipse. The eclipse, which will last one hour and 12 minutes, will be visible in North and South America, Europe, Africa and parts of Asia, according to NASA. But not all viewing locations are created equal.
In the United States, the Pacific Northwest and parts of the Midwest and Southwest will have the most clear visibility, according to an AccuWeather report. On the East Coast, better views are expected in the north than in the south thanks to a storm system in the area.
Despite experiencing relatively clear skies, viewers on the West Coast will miss out on the first part of the eclipse because of the timing of sunset.
No matter where in the country you may be, look for a spot with a clear view to the east, where the moon will rise. And if the weather doesn’t obey, or if you don’t want to leave the house, you can catch TIME’s livestream of the eclipse.
