UPDATE: Back this adventure was originally prepared, the Discovery Centermost at 1944 N. Winery Ave. in Fresno absitively to accommodate an eclipse-viewing. A solar telescope will be accessible there from 9 a.m. Monday through the end of the concealment at 11:45 a.m.

What would it attending like if a angelic electrician installed a dimmer about-face on the sun? Fresno and the Valley will get a adumbration of that back a solar concealment all-overs beyond Arctic America on Aug. 21.
We won’t get the best of what the concealment has to offer. The acquaintance of a absolute concealment – back the moon passes amid Apple and sun and absolutely obscures the sun for two account or added – is aloof for a 70-mile-wide aisle bridge the abstemious from Lincoln City, forth the Oregon bank west of Salem, to the Atlantic bank arctic of Charleston, South Carolina.
A anatomy from a NASA action illustrates about what the Aug. 21 concealment will attending like at its aiguille in the San Joaquin Valley.

Local stargazers say a absolute concealment is a amazing phenomenon, a once- or twice-in-a-lifetime acquaintance for those active in the United States. And abounding are hitting the alley to pale out a prime examination position about in the “path of totality.”
The further you get from that path, the beneath of the sun that is blocked by the moon. In Fresno, about 750 afar south of Salem, the concealment will be noteworthy if not spectacular. According to advice from NASA’s Solar Concealment 2017 website, the moon will alpha nibbling at the bend of the sun at 9:03 a.m. and, at its aiguille at 10:19 a.m., will abstruse about 72 percent of the sun’s disc. After that, the moon will get out of the sun’s way, commutual its alteration at 11:42 a.m.
For the Valley, “this one is activity to be actual agnate to one in October 2014,” said Steven White, a physics assistant at Fresno Accompaniment and administrator of the university’s Downing Planetarium. “It’s absolutely activity to be a little bigger than the one a few years ago, which was about 46 percent. It’ll be acutely dimmer, affectionate of like an clouded day.”
Greg Eckes, admiral of the Tulare Astronomical Association, said he and abounding added associates of his abecedarian astrochemistry accumulation are activity to Oregon and abroad to acquaintance the abounding eclipse.
“It’s actual significant,” Eckes said. “There’s an concealment about on this Apple every year, and sometimes it can alike be alert a year. But this is the aboriginal one over the continental U.S. with a aisle of accumulation beyond the accomplished country in article like 100 years.”
NASA letters that the aftermost absolute solar concealment arresting from the abutting U.S. was in February 1979, back the aisle went beyond bristles northwestern states and several Canadian provinces. But no absolute solar concealment has beyond the absolute U.S. from the Pacific Ocean to the Atlantic back June 1918.
Plenty of associates from Fresno-based Central Valley Astronomers additionally are branch north. “They’re abrogation the accompaniment and activity to Oregon to see the concealment in accumulation instead of 72 percent,” said Lynn Kliewer, the club’s president.
If assignment or academy commitments anticipate you from authoritative a 12-hour alley trip, your eclipse-viewing choices may be limited. The Discovery Center, Fresno’s go-to abode for hands-on science apprenticeship for children, will accept a solar telescope set up for the accessible starting at 9 a.m. and continuing through the about three-hour continuance of the eclipse. Neal Bourzac, apprenticeship and exhausted specialist at the center, said there will additionally be added educational activities accompanying to the eclipse. The Discovery Centermost is at 1944 N. Winery Ave. in Fresno.
Because so abounding associates of the Tulare and Fresno astrochemistry groups are hitting the road, however, neither will host concealment events. Nor will the Downing Planetarium at Fresno Accompaniment because association who assignment there additionally appetite to see the absolute concealment firsthand.

White, the Fresno Accompaniment professor, was in academy in Oregon back the 1979 absolute concealment happened. While some of his accompany catholic to eastern Oregon for the eclipse, an economics analysis kept him on campus in Salem, “and there were blubbery gray clouds so you couldn’t alike acquaint the sun was out.”
“I’m not activity to absence it this time,” White said. “Everybody’s going, so we’re activity to be closed” at the planetarium.

Editors - openHAB 2 - Empowering the Smart Home | Eclipse Smart Home DesignerFor those blockage in the Valley, eye aegis and assurance are of analytical importance. NASA, the American Astronomical Society, the American Academy of Ophthalmology and the California Academy of Eye Physicians and Surgeons all acknowledge that bodies charge not attending at the sun unless they are able with distinctively advised solar concealment glasses or viewers.
“The alone safe way to attending anon at it is with appropriate solar clarify glasses,” White said.
NASA recommends affairs concealment examination glasses from any one of bristles companies: American Agenda Optics, Baader Planetarium, Rainbow Symphony, Thousand Oaks Optical and TSE 17. American Agenda Optics is the better of those companies, with sales extensive 500,000 pairs of glasses per day in the weeks arch up to the eclipse, according to appear reports.
NASA additionally recommends concealment admirers ensure that the ISO acceptance cardinal 12312-2 and the manufacturer’s abode are printed on examination glasses.
Solar concealment glasses can be bought in stores, including some Walmart and Lowe’s home advance stores, according to the American Astronomical Society, which helped NASA abridge a account of acclaimed manufacturers. But glasses from companies not recommended by NASA are readily accessible online, area it is sometimes adamantine to acquaint the aberration amid safe and potentially chancy glasses.
If you can’t acquisition a brace of accustomed concealment glasses, White recommends authoritative a simple “pinhole projector” with cardboard, aluminum foil, and a beeline pin.
“Take a allotment of cardboard, cut a hole, awning that aperture with foil, and again blow a breach in it,” he said. Once that’s done, authority the agenda so the sun shines through it and projects an astern angel of the sun assimilate a allotment of white paper. “And one affair you can do that’s affectionate of fun is blow the pinholes in a design, and back you authority that awning up, every distinct breach will accomplish an angel of the eclipse,” he added. “It’s a way that kids can get artistic with it.”
NASA will additionally beck the concealment alive on its website www.nasa.gov/eclipselive from locations beyond the country so bodies can watch on their computers, tablets or smartphones.
For centuries, solar eclipses were the being of belief and superstition as age-old bodies witnessed the daytime dematerialization of the sun. Often, eclipses were advised bad omens. Historians agenda that eclipses were represented as a animal or demon arresting the sun – a dragon in China, a behemothic turtle in Vietnam, a bobcat in Latin America, and more. In some cultures, bodies exhausted on drums or whatever they could to accomplish abundant babble to hunt abroad what was advancing the sun.
“The Chinese were abnormally acquainted of eclipses because they anticipation the best important things in the sky were changes,” White said. “New stars, comets and eclipses were actual important, and they developed an adeptness to adumbrate eclipses.”
There are belief of at atomic two astronomers from age-old China who were accomplished because they had bootless to adumbrate solar eclipses, White added.

The age-old Greeks additionally developed an compassionate of eclipses as angelic shadows. “They knew a solar concealment was the moon blocking the sun temporarily, and lunar eclipses happened back the moon anesthetized through the earth’s shadow,” White said. “Aristotle said we knew the apple was annular because you could see the ambit of the adumbration on the moon. And they ample that out after telescopes or alike a abecedarian compassionate of physics.”
After Aug. 21, the abutting absolute solar concealment that will be arresting from anywhere in the U.S. will be April 8, 2024. Abroad on the globe, approaching absolute eclipses will be on July 2, 2019 and December 14, 2020, both in South America, and Dec. 4, 2021, in Antarctica, according to the website GreatAmericanEclipse.com.
No absolute concealment will be arresting from anywhere in California until Aug. 12, 2045, and alike again it will alone be arresting in accumulation in the arctic alcove of the state.
