Save eclipse glasses for next big solar event

 

The next time a total solar eclipse crosses the United States isn’t that far off. It’s April 8, 2024

If you didn’t have a chance to experience totality on Aug. 21, 2017 you might want to plan where you want to see it next time. Even if you don’t go you might know someone who will. So save those eclipse glasses if lucky enough to have a pair.

Carbondale, IL will again be dead center when the eclipse path crosses the United States. But the path of the 2024 total solar eclipse will cut the opposite direction. It will go from Mexico in the southwest to Maine in the northeast as it moves across Texas, Arkansas, Indiana, Ohio, New York and Vermont.

Consider then, taking a spring vacation in Austin or Dallas Texas, Indianapolis, Toledo or Cleveland, Ohio or the Buffalo, Niagara Falls area or even Montreal. Chicago won’t be in the direct total solar eclipse path until Sept. 14, 2099.

To go now to walk across the map visit Adler Planetarium’s “Chasing Eclipses” exhibit. It has a terrific floor map of the total solar eclipse path for 2017, 2024 and 2099.

The Adler also has a total solar eclipse experience at one end of the exhibit complete with cooler air, expected sounds and a good visual eclipse.

 

Why experience totality

The following quote from Adler Astronomer Larry Ciupik, the Doane Observatory director,  describes what he saw in Capo San Lucas, Mexico July 1991.

“It didn’t matter how much I knew about it or prepared for it, my first total solar eclipse was unexpected and unlike anything I’ve ever seen!” Ciupik said on an Adler web site.

He went on to explain. “In the last few seconds before totality, the sky darkened to a deep blue, then purple, and faint wavering lines appeared—shadow bands—whisking across the sand of our beachside site. Suddenly, the Sun itself dramatically changed. I took off my special solar viewing filter and saw what looked like a hole in the sky surrounded by a pearlescent glow. The Sun’s outer atmosphere, the corona, resembled outstretched wings several times wider than the hole on each side.”

Also, totality will last longer on its path. It will range from three minutes plus seconds to four minutes plus seconds over most of the United States in April 2024 instead of the two minutes plus seconds it did  in August 2017.  For the 2024 path click here and at Time and Date.

Checking locations

To figure the time of the eclipse in the city you want to visit check its latitude and longitude then go to NASA Path.

The information is thanks to NASA and Fred Espenak.  The numbers are in Universal Time so for central daylight time subtract 5 hours and eastern daylight time subtract 4 hours.

Another good resource is Earth Sky. For another map of eclipses see EarthSky Essentials.

 

Adler Exhibit

“Chasing Eclipses”is up now through through Jan. 8, 2018. The Adler Planetarium is on the Museum campus at 1300 South Lake Shore Drive Chicago, IL 60605. For ticket and other information visit Adler Planetarium and call (312) 922-7827.

 

 

 

Where to watch solar eclipse in Metropolitan Chicago

 

Just about everyone in the Chicago area knows that the moon will block out most of the sun midday, Monday,  Aug. 21, 2017.

And most of them have heard that they need the certified glasses to watch the event or watch through a hole aimed at the ground where they see the event’s shadow.

Chicago will be in about 87 percent darkness during the height of the eclipse by 1:19 p.m. which is enough to feel the temperature change and that night has come.

So, the question is where to watch. Certainly Chicago’s TV channels, including WGN,  will be broadcasting. But to experience the event with others check the places listed here and your local library, park district, forest preserve district or junior college.

 

 

Adler Planetarium on the Museum campus at 1300 S. Lake Shore Dr, Chicago, provides the best overall experience because along with giving out the proper glasses at no charge, it will have free general admission so visitors can see its “Chasing Eclipses exhibit. The Adler will also have lots of outdoor activities. For details visit Adler Eclipse Fest.

 

Chicago Botanic Garden at 1000 Lake Cook Rd., Glencoe, is holding a viewing party from about 11 a.m. to 3 p.m. on the Esplanade and in the Krasberg Rose Garden. The event includes free solar glasses (one per family while supplies last) that will begin distribution at 10 a.m. There will also be other activities. For details visit Botanic Garden Eclipse.

 

Chicago Park District will host eclipse events at 20 parks and include glasses provided by the Adler Planetarium until they run out. For park locations visit Chicago Park District Eclipse.

 

Chicago Public Library will host viewing events at several branches. For the one nearest you click CPL Events.

 

Evanston Public Library, 1703 Orrington Ave., Evanston, will have a viewing party at its main location on Orrington Avenue from 11 a.m. to 3 p.m. For more details visit EPL.

 

Lake County Forest Preserve District has a solar eclipse viewing party  at Ryerson Woods, 21950 N. Riverwoods Rd, Riverwoods, from 11:30 a.m. to 3 p.m..

Where to be August 21 in 2017

 

If standing in the right place at the right time, your world will start to get cooler as the sun seems to disappear. Then, it will be dark and chilly. And no, you won’t be watching a sci-fi movie or be experiencing the end of the world as described in mythology. You will be experiencing a total solar eclipse.

Unless you plan to be in the south Pacific or South America on Dec. 14, 2020 or in Dallas, Indianapolis or Cleveland, April 8, 2024, your best bet to experience a total solar eclipse is in the United States Aug. 21, 2017 along a diagonal path from  Salem, Oregon in the northwest through Carbondale, IL in the Midwest to Charleston, South Carolina in the southeast.

 

Direct Time and Place

In the Midwest, people who travel to Carbondale in southern Illinois will see the moon totally blocking the sun for about 2 minutes and 41.6 sec. It’s actually safe to look when the sun is totally covered then. but not before or afterwards. If you don’t think that’s a long time to be in the dark try watching a clock tick off the seconds.

Carbondale, home of Southern Illinois University,  is one of the best places to go to because of the long blockage beginning at 1:20 p.m. CDT and because it is one of NASA’s official sites. The Adler will have an event in Carbondale where astronomers and eclipse chasers will converge. Total coverage last about 2 minutes and 42 seconds.

You can draw your own line on a map from Salem, OR to Charleston, SC to see what other towns are in the eclipse path. Even though the blockage won’t be as long as in Carbonadale they will have a total eclipse. The towns along the path are all expecting visitors so are hosting eclipse events.

For example for Oregon visit Salem, Madras and Oregon for festivals, where to stay and what to do. If near Salem the eclipse is at 10:19 a.m. PDT and lasts 2 min, 4 sec.

For Carbondale, go to SIU. Totality there happens at 1:20 CDT.  Also check out Charleston where the eclipse ends on US soil. Charleston is in the dark for about one minute, 40 seconds. For other places in South Carolina visit Great American Eclipse SC .

Accommodations have been going fast along the eclipse path so if planning to travel to a city where there will be total darkness don’t wait to find a place to stay whether camping or looking for an inn.

 

Chicago

Those places mentioned are dead center on the path but that doesn’t mean you wont have a great eclipse moment several miles away.

At the Adler's "Chasing Eclipses" exhibit, astronomer Larry Ciupik points out where Carbondale is on the 2017 eclipse path that goes from left to right. It is bisected by the eclipse path that will run from southeast to north west in 2024.

In Chicago, the moon will begin blocking the sun about 11:54 a.m.CDT,  reach maximum coverage about 1:30 p.m. and be all the way through by 2:30 p.m.

“While it won’t be absolute total blockage in Chicago, the city will experience a 90 percent eclipse,” said Adler Planetarium astronomer Larry Ciupik. And that is with Chicago located about a six and a half hour drive north of Carbondale.

Thousands of people are expected to join the Adler’s watching party, according to Ciupik. Proper glasses will be handed out until the supply is gone. For the Adler’s big eclipse bash visit Adler Eclipse. For official NASA viewing sites visit NASA Event Locations.

 

Safety

It’s not OK to look while the moon is moving across the sun even when a little bit of the sun is peeking out. Looking at the sun when there is not total blockage will damage the eyes. See NASA for more eclipse information and NASA Safety for viewing tips.

You have to use certified glasses to watch. Another way is to look at the events shadow on the ground by turning your back to the sun and making a peep hole with your hands, one in front of the other as described on the NASA safety site.

 

So take advantage of the event by making it a summer vacation but don’t wait to make arrangements.

 

 

 

 

Sky happenings: Launches and meteors

Space events April 16 to 23 make this is a good week to link to NASA and look up.

 

If “Hidden Figures”  rekindled interest in NASA, its launches and its people, now is prime time to see what’s happening.

Beginning at 10 a.m. CT today, April 18, NASA is launching Orbital ATK CRS-7, a cargo mission to resupply the Space Station. Click here for more information and to watch it.

Secondly, very early in the morning of April 20 at 2:13 a.m. CT is the launch of the Expedition 51 crew to the Space Station. Visit launch for information on the Expedition 51 crew and how to watch it on TV.

 

Then, during the predawn hours of April 22 , look up to the north east to spy meteors streaking across the sky. They are the Lyrids which are debris from Comet C-1861 G1 Thatcher near the bright Vega star. Vega is in the Lyra Constellation.

The Geminid meteor shower is greater than the Lyrids but meteor showers are still awesome to see. segment of a NASA photo

The Lyrids actually began Sunday, April 16 but they peak early Saturday after Vega is high in the sky well after midnight.

Considered the oldest observable shower, it was first noted more than 2,600 years ago.

A good site for more Lyrids information is Time and Date
