If in Chicago, rain or cloudy skies may prevent you from seeing the Harvest Moon Oct. 5, but if you are elsewhere in the Northern Hemisphere you should be able to see what looks like a large, orangey-toned impressive orb. (The moon also looked impressive Chicago Oct. 4 when the weather cleared).

It’s dubbed the Harvest Moon because it is the full moon closest to the autumn equinox when farmers enjoy more moonlight to finish harvesting their crops.

That’s because even though the moon typically rises 50 minutes later each fall and winter day, the moon’s orbital path is narrower in the Northern Hemisphere near the autumn equinox. That orbit makes it rise only about 35 minutes later each day.

BTW, the orange color is noticed when seeing the moon through the Earth’s atmosphere near the horizon. The moon also looks larger from that angle.

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.

 

 

 

Chicago hosts World Roller Derby where it all began

 

If you remember when you used to roller skate in the neighborhood or go to a local rink to roller skate, or if you like things retro, then mark down Aug. 19, when the World Roller Derby game will be played in south suburban Summit using 1970s rules and classic uniforms.

If you like the idea of celebrating a sport in the city where it began, then head to the former site of the Chicago Coliseum on Aug. 13

Roller Derby athletes and fans will be there to mark Chicagoan Leo Seltzer’s organizing the first Roller Derby Race where it first took place, Aug. 13, 1935.

 

Event Info

For the Aug. 13 celebration, go from 12:30 to 2 p.m. to Coliseum Park at 1513 S. Wabash Ave.

To see the retro roller derby game, a double header from 2  to 6 p.m., go to the Fleetwood Roller Rink, at 7231 W. Archer Ave. in Summit (south of Brookfield and I 55), Aug. 19.

Participants  will be wearing the classic uniforms of the Midwest Pioneers and the Chicago Westerners using the 1970s rules. There will also be a Junior Roller Derby game.

Tickets are needed and limited so contact Brown Paper Tickets, a World Roller Derby Week partner, at Time Hop.

”We want to look back at our roots, pay respect to its founding members and to the city of Chicago, to celebrate our beginnings and progress, and give back to the community through service,” said World Roller Derby Week organizer Cheryl Cryer. “The roller derby story should be shared broadly as we look to our future in our juniors, who will no doubt carry us further than we could ever imagine.” Cryer said.

The event is also partnering with the American Red Cross for a national blood drive. Donor Pledges will be available at the events.

 

Hall of Fame

Raise you hands if you knew there is a Roller Derby Hall of Fame. You can find out about the sport and who is inducted there by clicking Roller Derby.

It was housed at NYC’s  Madison Square Garden in the early 70s, closed. But the sport hasn’t disappeared. There are nearly two thousand women’s, men’s and junior leagues skating and competing.  The Hall of fame reopened in Brooklyn in the early 2000s and will be moving to southern California soon.

Meteor Watch

 

Look up at night or just before dawn. You might see a meteorite zooming across the sky from now through mid August.

NASA captures meteor shower

The Delta Aquarid meteor shower which peaks July 28 is best viewed in the Southern Hemisphere but you might see a flash of light looking south. This week is fairly good to sky watch because there is a waxing crescent (just a sliver of a moon).

In addition, the Northern Hemisphere’s popular Perseid meteor shower that peaks Aug. 12/13 in 2017, has already started so you might catch one of its meteorites almost anywhere in the sky.

Unfortunately for Perseid watchers, following a full moon Aug. 7, there will be a waning gibbous moon with about 77 percent illumination Aug. 12 and 67 percent illumination Aug. 13, so the moonlight will make it harder to pick up the meteorites. The Perseids can still be seen though there are fewer of them during the next waxing moon Aug. 16-18.

 

The Delta Aquarids and Perseids

The Aquarids are named for Skat, a star whose Greek name is Delta Aquarid. The star is below the Great Square of Pegasus in the Piscis Austrinus constellation. For more Aquarids info and a meteor shower calendar click on Earth Sky.

The Perseids go all over the sky but radiate from the Perseus constellation. They are coming from the Swift-Tuttle comet. You see them when Earth crosses its orbit. Visit NASA and Meteors for NASA’s Perseid information
