Open House Chicago, a free glimpse inside historically, architecturally and culturally significant buildings, churches, homes theaters and museums not normally open free to the public, will have open doors this weekend, Oct. 14 and 15, from 10 a.m. to 5 p.m., thanks to the Chicago Architecture Center.
What to expect: Chicago is a city of neighborhoods. The sites open this weekend are in neighborhoods ranging from Andersonville/ Edgewater and Beverly/Morgan Park through Bronzeville/Downtown and Hyde Park to Logan Square, Pullman and Uptown.
This festival is an extraordinary opportunity to explore some of the city’s great places in more that 20 neighborhoods.
Among the sites is the Pullman National Historical Park and the historic Fine Arts Building 410 S. Michigan Ave. that has been featured this week in the Sun Times and Chicago Tribune
Tip: many places will have lines but Chicago Architecture Center Members will receive a priority access pass so of living in the area or have plans to return and take its fame boat or an architecture tour, membership is a good deal.

here are always meteors flying overhead. A good overview is at NASA.GovSo don’t worry if you miss one group in the news. You can watch for others that peak a short time later.
In October the Draconids peak Oct. 8-9 with best chance to catch theses somewhat sparce meteors shortly after nightfall. They are the dust particles from the Comet 21P/Giacobini-Zinner. Visit SPACE for a detailed graph of the radiation point.
But if you miss them, the more prolific Orionid meteor shower which can produce between 30 to 80 meteors pers hour, will peak about ten days later Oct. 20-21. They come from the debris of Comet 1P/Halley, (Halley’s Comet). For more information visit Time and Date.
Some sky sites say September’s full moon appears on the 28th of the month. Others say look for it on the 29th. They are both right. The crest of the full moon is 4:57 a.m. CDT on Sept. 29. But you will see the full moon which is another of this year’s supermoons, at sunset on Sept. 28. I like EarthSky for this information.
Followers of Travel Smart know that full moons have different names. Some relate to the season’s weather or crops while others connect to Native American, Celtic and other cultures.
Not surprisingly, September 2023 is the Harvest Moon because it is the full moon closest to the fall equinox, Sept. 23. It is also called the corn moon.
Unless the weather interfers, it will be easy to see. Its larger than usual size and brightness has to do with its closeness to earth and not anything extra.
If you like finding planets in relations to the moon, look for Saturn an hour earlier. It will be moving through the sky ahead of the full moon. Jupiter will be tagging along after the moon.
Another good sky site to find more information is Time and Date.
As nights get colder, leaves are turning gold, scarlet and copper. It’s the Fall or September Equinox. And, drum roll, it is happening Sept 23, 2023 at 2:50 a.m. EDT in the Northern Hemisphere.
The exact time is when the sun crosses the equator when going south from the north. The occasion is also known as the astronomical date for fall.
Vacationers wanting to head to the Southern Hemisphere know that the season will be warm because fall there doesn’t start until in March.
Meteorologists define fall using the average temperature change which happens the first day of the equinox month so their fall definition in the Northern Hemisphere began Sept. 1.
It’s likely you don’t need to be told that the days are getting shorter and night are longer. We seem to want to stay in bed longer and maybe change our schedules to use more daylight.
But at the Equinox they are equal before they continue in their short and long time spans.
Thus, the shortest day of the year is at the winter solstice. For more information and fun facts visit The Old Farmer’s Almanac.
August 2023 ends with a “Blue Moon” but it’s not blue.
The month also ends with a “Supermoon” that seems larger than usual. But even though it appears larger, the moon didn’t actually grow.
It also ends with a full moon. And yes, at full illumination it is full. So what is happening?
First, the phrase “once in a blue moon” came about because it is a somewhat rare occurence. It refers to having two full moons in one month. When a month starts out with a full moon it has enough days to complete the moon’s phase cycle with a second full moon as has happened in the 31 days of August 2023. (It can also be a seasonal blue month it is the third full moon in one season).
Time and Date notes that the last Super Blue Moon was December 2009, and the next one is August 2032. Also, that the next Blue Moon is August 2024, but it isn’t a Supermoon.
According to Space, our second August moon will look larger and brighter than other full moons in 2023. It is one of the year’s Supermoons, a moon that is full at the same time its orbit brings it closest to Earth (perigee).
But the second August full moon will be closer to earth than the other Supermoons. The average distance to the moon according to many scientific sites is 238,855 miles.
However, this August moon will be 221.942 miles, Aug. 30 at 9:36 p.m. EDT.
I like the NASA Science site that explains the August Blue Supermoon.
If you have clear skies and can watch after midnight, chances are good that you can catch way more than one “falling ” star this weekend.
The bright, prolific Perseids, will be shooting debris from the 109P/ Swift- Tuttle comet at 90 or more meteors per hour late at night, Aug. 11-13 and peaking Aug. the 13th. The moon is a waning crescent so shouldn’t be a light factor.
They already started in mid-July and continue until Sept 1 but this weekend is expected to be their biggest display.
They are fun to watch as they are fast (37 miles per second) and are streaks of light with long trains or “wakes.” Plus, they are usually colorful.
Best time to look is very, very early in the morning before the sun rises. They shoot all over the sky but the radiant (where they seem to come from) is the northern section of constellation Perseus which is higher in the sky shortly before dawn.
For more information and charts visit NASA and EarthSky
Sky watchers might catch a glimpse of the Capricornids. They are not abundant but if you see a bright slash across the sky it’s likely to be a Capricornid meteor. They peaked July 26 but are continuing through mid-August.
Look for the triangular Capricornus (Sea Goat) constellation for the Capricornid radiant.
Then be rewarded for looking up the beginning of August when the Delta Aquarids fly across the sky at about 10 per hour.
They peaked July 29 but continue through Aug. 19. However, you might miss some because they are not bright and don’t have a noticeable tail.
For their radiant look for Aquarius the Water Bearer (see a triangle of stars with a fourth star in the middle) between Capricornus and Pegasis’ Great Square.
Next, watch for the Perseids in mid-August. They are already shooting across the sky but will peak about Aug. 13-15 and continue through Aug. 24.
They come from the Swift-Tuttle also are abundant but more easily seen than the Delta Aquarids.
You likely heard the phrase, ‘once in a blue moon.’ It’s about rarity, not color. It’s when one month boasts two full moons. And August 2023 is a prime example.
First, watch for the first full moon, called the Sturgeon Moon, on Aug.1, Peak illumination is 2:32 p.m. Eastern Time, but you should be watching for it after sunset when it’s more visible as it rises in the east.
It is also a Supermoon. Because its orbit brings it close to earth it will appear larger and brighter.
As for its name, it refers to when the Great Lakes’ huge sturgeon are often caught. Menacing looking, it is the North America’s largest fish and is considered prehistoric (136 million years ago) in origin.
For a great Sturgeon exhibit, check out Grand Rapics, MI’s Public Musuem.
The August moon is also called the “Corn” moon by some Native American tribes and many farmers.
Then, look skyward at the end of the month for the second full moon. What we call a “Blue Moon” appears August 30 with peak illumination at 9:36 p.m. ET.
Its appearance late in the month begins the later cycle of monthly full moon dates.
One other full moon note is that the moon will appear full the day before peak illumination and the day after so expect more night lite and picture taking ops.
If you love snapping photos of a full moon, particularly a supermoon, you’ll love this summer season of 2023.
There’s not just one supermoon. There will be four of them lighting up the sky between July 1 and Sept. 28. Yes, there will be what is called a “blue moon.”
As NASA’s Solar System Exploration site explains (NASA capitalizes Earth and Moon when referring to specific planetary orbs), “a supermoon occurs when a full moon coincides with the Moon’s closest approach to Earth in its elliptical orbit, a point known as perigee.”
That point is less than 226,000 miles from earth so its closeness means the moon will look larger than usual. It’s called a ‘supermoon’ if within 90 percent of perigee.
Different scientific organizations and sites use different calculations. The word “supermoon” as known today was first used by astrologer Richard Nolle in 1979.
The EarthSky website uses supermoon dates and times determined by astronomer Fred Espenak, who worked at the Goddard Space Flight Center. Espenak takes in account changes in the moon’s orbit per lunar cycle.
Earth/Sky uses the Astropixels table for the upcoming supermoons:
July 2-3: 224,895 miles (361,934 km), Aug 1: 222,158 miles (357,530 km), Aug 30-31: 222,043 miles (357,344 km), Sept 28-29: 224,658 miles (361,552 km).
As you look at the different distances you see that the second August supermoon is the closest. And you understand that with two full moons in the same month we’re talking about “once in a blue moon” meaning the rarity of two full moons in the same month.
That second full moon now marks the start of a cycle where the moon is full later in a month as opposed to the early monthly dates we saw so far in 2023.
Ready for the July 2023 Supermoon? The Old Farmer’s Almanac calls it the Buck Moon because the male deer’ antlers are in full growth. The bucks shed and regrow antlers producing a larger set each year.
Other July full moon names reference animal and plant changes such as the Salmon Moon, Ripe Corn and Berry Moon.
When to get the camera (phone) ready? The July supermoon is at peak illumination at 7:39 a.m. ET. July 3, the but will look full July 2 and July 4 so you may get an interesting photo during your local fireworks celebration. But try to also get a photo without fireworks lighting up the sky.

When do you think summer starts? Is it when school ends or weather turns warm enough to swim outdoors? Or it could be when your local meteorologist announces astronomical summer.
In the Northern Hemisphere the Summer (June) Solstice is June 21 in the year 2023.
Take advantage of the June Solstice, also called the Summer Solstice. It is the longest day and shortest night and this year. So, there is more daylight to work in the yard, take long walks, eat dinner out on the patio or just enjoy summer. Just remember to use sunscreen.
The Old Farmers’ Almanac says the actual solstice moment comes at 10:58 a.m. EDT.
For its meaning, think Latin sol for sun and sistere for standing still. IKt certainly stands still in the Arctic Circle which won’t get dark because the sun won’t set there. Think Midnight Sun.
Earth/Sky, The Farmer’s Almanac and Space explain the long day relates to the sun’s angle to the Equator and is the farthest north of the horizon in the Northern Hemisphere.
NASA explains the long day is due to the tilt of the Earth and has a graphic showing the angle.
Of course, such a momentous time of year has related folklore. Most of those events come under the title Midsummer.
That may sound as a misnomer, but the June Solstice marking the beginning of the season is a starting point that is usually marked a few days later with Midsummer celebrations. It’s when many northern cultures such as Sweden, Finland and Ireland historically celebrated the time with rituals, visits to Stonehenge, and religious occasions.
Maybe hold your own Midsummer celebration. Check Travel Sweden for how they do it and their Midsummer dates.
