For the first time in decades, the United States will be treated to a total solar eclipse.

On Monday, August 21st, the moon will completely cover the moon stretching from Salem, Oregon to Charleston, South Carolina.

"All of a sudden you are immersed in darkness and you see this bright corona shimmering in the the sky.. it's something very, very unique," University of Hawaii Institute for Astronomy, astronomer, Shadia Rifai Habbal said.

While many observers coast to coast on the mainland will get to see the total solar eclipse, Hawaii can expect something a little different come Monday.

"You'll see roughly a quarter of the sun missing even as the sun comes up," said Mike Shanahan, Bishop Museum planetarium director. "Basically, the sun will look like a cookie with a bite taken out."

A partial solar eclipse will be visible in Honolulu, starting around 6:15 a.m., Monday and is expected to last a little more than an hour, according to Shanahan.

Times will vary on other islands depending on when the sun rises. Although, the maximum partial eclipse in Hawaii is expected to happen approximately at 6:35 a.m, Monday morning. 

"During a partial solar eclipse.. if you didn't know it was going on. If you weren't viewing it with a safe filter .. you'd have no idea anything is going on," Shanahan said.

Experts are reminding observers not to look directly at the sun and to use special-purpose solar filters, such as “eclipse glasses” or hand-held solar viewers.

Additionally, Shanahan says two more things to keep in mind if you are planning to watch the partial eclipse in Hawaii is weather and location.

"Go for a place that has a good chance of clear weather and you absolutely need a flat horizon looking toward the east," he said. 

The planetarium director told Island News Monday's partial solar eclipse won't happen again for another seven years.

"We're entering a serious drought for any flavor of solar eclipse.. usually you get a partial solar eclipse in Hawaii or anywhere on earth every year, year in a half.. after Monday there will not be a partial solar eclipse until April of 2024," Shanahan added.

As for the next total solar eclipse expected in Hawaii, we're told that won't happen until the year 2106.
