Rare 'ring of fire' eclipse event Saturday

An annular solar eclipse creates a "ring of fire" around the moon, similar to what is seen in this image taken by the JAXA/NASA Hinode spacecraft. A "ring of fire" eclipse will take place Saturday across the U.S. and into Central and Southern America.

A rare "ring of fire" annular solar eclipse will form overhead Saturday morning.
Although North Idaho isn't directly in the path of annularity, those who look to the skies with proper eclipse-viewing glasses should be in for a celestial treat. The eclipse over Coeur d'Alene will begin at 8:09 a.m., maximize at 9:23 a.m. and conclude at 10:44 a.m., by calculations of the U.S. Navy's online Solar Eclipse Computer.
Annular solar eclipses occur when the moon is near or at its farthest point from Earth. The sun won't be entirely blocked out by the small-looking moon as it passes between planet and star, thus creating a brilliant "ring of fire" effect of sunlight around the moon at the peak of the eclipse.
"What I’ve heard the weather forecasters say, which is totally wrong, is because the moon is smaller we will not get totality. That gives the impression that the moon is variable in size," astronomer John Taylor, of Hayden, said Thursday. "The moon's orbit is not circular, it's orbital, that's what causes super moons. This is a case where the moon is farther away so it can't cover the entire surface of the sun."
The eclipse will cross North, Central and South America and is expected to be seen by millions of people in the Western Hemisphere.
"For NASA, this eclipse provides a unique opportunity to study the sun, using this eclipse as a way to test and prepare scientific equipment for the total solar eclipse in April 2024," NASA said on its website, science.nasa.gov. "NASA will also launch sounding rockets during the eclipse to study changes in the atmosphere."
Using lunar topography data from NASA's Lunar Reconnaissance Orbiter and the Japan Aerospace Exploration Agency's SELENE lunar orbiter, a map of the precise calculation of the location of the moon's shadow has been posted at science.nasa.gov/eclipses/media-resources. The path of annularity and partial visibility crossing the U.S. is shown to be over central and southern Oregon and stretches southeast to Texas, sweeping farther to the southeast.
North Idaho will be in the 70-80% range of obscuration of the sun during the eclipse, according to NASA data.
Taylor witnessed the last annular solar eclipse from Mount Lassen in California 2012. He said the big difference between a total solar eclipse and an annular eclipse is how bright it is.
"Don't look directly at it," he said. "You can get away with it for a few seconds with a total solar eclipse, but not this one. You will need those good-looking eclipse glasses to see this one, or use a piece of cardboard with a pinhole in it and let that cast a shadow on the ground and you will see the eclipse."

It may be a challenge to see the full spectacle, as cloudy skies are forecast.
Taylor said he'll spend Saturday morning "swearing at the clouds" that will obscure the eclipse.
"We are not going to see it," he said. "It's unfortunate but true."
The most southwestern corner of Idaho and areas across Oregon will receive the best viewing experience from within the full annularity zones.

Wearing safety gloves and magenta headphones with a galaxy design, Autumn Parks rested a long piece of lumber on a picnic table as she smoothed out the edges. “I’m sanding it down so nobody gets splinters when they go to bed," she said. As an American Heritage Girl, Autumn already had some experience working with lumber. “I made a staff this August, a walking stick, and it taught me how to sand,” she said. “I thought, 'I can sand, let’s do that!” The Hayden Canyon Charter seventh grader shared how she thought it was really cool that her school was building beds for kids in need.

Controversial AI exhibit at Art Spirit Gallery runs through Dec. 24, community event Saturday
Mike Baker installed his exhibit at the Art Spirit Gallery hoping it would generate conversations in the community. And wow, did it ever. "No Permission Needed," featuring pieces created using artificial intelligence, debuted Nov. 14 at the downtown gallery. It quickly became a subject of social media discussion and scrutiny in the arts community and the community at large for the use of AI and female experiences being brought into focus by a male, with some accusing Baker of misogyny, art theft or posing as an artist while others defended the intention behind the project and the exploration of a new technology-based medium. "At the end of the day it’s focused on women’s health, all rooted in the work we’ve done around endometriosis and tied to the experiences people have shared with me and that I’ve seen walking through the health care system,” Baker said Thursday. “I was just trying to capture all of that within it."
