Total Solar Eclipse

From a long time member of NewMars Palomar aka elsewhere

And roughly 15 minutes prior to Noon. I'll definitely step out to see it! smile Safely, of course.


The chance to view will be just the once on earth but on the Space station crew to get three shots at solar eclipse

For the station crew, the first partial eclipse opportunity will begin at 12:33 a.m. EDT (GMT-4) and end 13 minutes later.

The International Space Station's crew will enjoy views of the Aug. 21 solar eclipse during three successive orbits, giving the astronauts a unique opportunity to take in the celestial show from 250 miles up as the moon's shadow races across from the Pacific Ocean and the continental United States before moving out over the Atlantic.

"Because we're going around the Earth every 90 minutes, about the time it takes the sun to cross the U.S., we'll get to see it three times,"

Re: Total Solar Eclipse

NASA jets will chase solar eclipse at 50,000 feet

On Monday, a total solar eclipse will travel coast-to-coast in the U.S. for the first time in 99 years. Four NASA flight crew members who will be chasing the eclipse over Missouri, Illinois and Kentucky at 460 mph.

"These planes will be outfitted with special cameras in their nose cones," Caspi said. "So the planes … will be looking at the solar corona, the outer atmosphere of the sun." "Our results will lead to a better understanding of the corona, which will eventually lead to a better understanding of ...flares and coronal mass ejections," Caspi said.

"They can cause blackouts of radio frequency communications. Cell phones can have trouble working," Caspi explained. "It can cause power outages by knocking out power grids."

The best way to understand what erupts off the sun's corona is to photograph it over long periods of time. But ground-based cameras will only have about two minutes of total eclipse time.

Because two of the planes will be flying tandem along the eclipse path, it will give scientists an unprecedented look at the sun.

"Each plane will be able to observe totality for about four minutes. And when we stitch together the observations from both of the airplanes, we be getting  about seven- to seven-and-a-half minutes of total solar eclipse," Caspi said. "We'll be getting 30 photographs a second for seven-and-a-half minutes of totality. … That's about 29,000 photographs between the two airplanes."

Re: Total Solar Eclipse

Solar eclipse could cost employers big in lost productivity

Tell them to punch out or to use vacation time to cover there non work time not sick.

The first solar eclipse visible in the U.S. since 1979 will take place in the middle of the workday, which may cost employers as much as $694 million in lost productivity, according to global outplacement and coaching firm Challenger, Grey & Christmas, which analyzed wage and employment data from the Bureau of Labor Statistics.

States and cities in the path of the eclipse, which stretches from Oregon to South Carolina, could suffer productivity losses of almost $200 million.

Re: Total Solar Eclipse

Where I live,  the eclipse was around 70% area coverage partial.  I noticed a distinct lack of radiant skin heating.  The air only cooled a degree or two,  by my front porch thermometer.  I'm waiting for April 8,  2024,  when totality passes over my house. 

My welding hood and glasses were inappropriate to solar brightness.  So we did the pinhole "camera" thing as a small hole in a 3x5 card held about a yard from a sheet of white paper on a clipboard.  It worked,  just like it always does.  Digital phone camera shots of this didn't pan out very good,  because the brightness of the reflection from the unshadowed part of the paper messed up the camera's automatic irising for overall image brightness. 

What was just as effective and a whole lot more startling was the images cast amongst the shadows by the effective pinholes through the leaves of bushes and trees.  My wife didn't believe it until I showed it to her.  Almost all our bushes and trees casting shadows onto truly flat surfaces showed images of the eclipsed sun at one or another level of focus quality. 

Our best photos came from this effect where front porch bushes cast shadows and images onto the flat concrete slab of my front porch,  which is south-facing.  You pick the one of many images that looks best-focused,  and watch that.  Easy as pie,  and very,  very safe for the eyes.

Re: Total Solar Eclipse

April 8, 2024,  New Hampshire 100 days away from first total solar eclipse since 1959

The totality path will cross northern Vermont (including Burlington), southern Canada (including Montreal), northern New Hampshire and a large swath of northern Maine.

New Hampshire communities along the path include Lancaster, Stark, Northumberland, Milan, Dummer, Errol, Dixville Notch and Pittsburg.

Totality will last about 3 minutes and 30 seconds.

The peak in New Hampshire will be about 3:30 p.m. For the rest of the state, the sun will be obscured by 95% or more at the peak.

2079

In 56 years, on May 1, 2079, New Hampshire will experience totality again.
