Hawai‘i Has Best View Of Total Lunar Eclipse Combined With Supermoon

In this Monday, Jan. 21, 2019 file photo, the Earth's shadow falls across the full moon seen above Brighton, southeast England.

The first total lunar eclipse in more than two years coincides with a supermoon this week for quite a cosmic show and Hawai‘i has the best seat in the house, a NASA scientist said.

This super “blood” moon will be visible Wednesday across the Pacific — offering the best viewing — as well as the western half of North America, bottom of South America and eastern Asia. Stargazers will be able to see the total lunar eclipse starting around 4:11 a.m. on the West Coast and 1:11 a.m. in Hawai‘i.

You'll want to find a cloud-free place with low light pollution to watch the eclipse, said Roy Gal, an associate astronomer at the University of Hawai‘i Institute for Astronomy.

"If you go somewhere like Sandy Beach or Waianae or North Shore, you'll probably get a good view," Gal said. "If you want to see a little bit more detail on the moon, you can just break out a pair of binoculars or you can join the live stream that we're going to have online."

Better look quick: The total eclipse will last about 15 minutes as Earth passes directly between the moon and the sun. But the entire show will last five hours, as Earth's shadow gradually covers the moon, then starts to ebb. The reddish-orange color is the result of all the sunrises and sunsets in Earth’s atmosphere projected onto the surface of the eclipsed moon.

“Hawaii has the best seat in the house and then short of that will be California and the Pacific Northwest,” said NASA’s Noah Petro, project scientist for the Lunar Reconnaissance Orbiter. New Zealand and Australia also will have prime viewing.

Circling the moon for 12 years, the orbiter will measure temperature changes on the lunar surface during the eclipse. Telescopes atop Hawaii’s Mauna Kea also will monitor the moon, Petro said.

The moon will be setting and the sun rising along the U.S. East Coast, leaving skygazers — Petro in Virginia included — pretty much out of luck. Europe, Africa and western Asia will miss everything. There will be livestreams available.

Everyone everywhere, though, can still soak in the brighter than usual moon, weather permitting.

The moon will be more than 220,000 miles (357,460 kilometers) away at its fullest. It's this proximity, combined with a full moon, that qualifies it as a supermoon, making it appear slightly bigger and more brilliant in the sky.

Last month’s supermoon, by contrast, was 96 miles (155 kilometers) more distant.

Unlike a solar eclipse, there's no harm in looking at an eclipsed moon.

More lunar shows are on the horizon.

“For people who might feel like we’re missing out, set your calendars for Nov. 19 of this year,” Petro said. This will be a nearly total eclipse where the moon dims but doesn’t turn red.

The next total lunar eclipse will be May 2022. The last one was January 2019.
