I believe we’re all aware that the amount of light has major influence on wildlife activity, as it does our own, triggering everything from breeding and feeding activity and various behaviors in general. Thus the very short period of light variation during a solar eclipse has piqued my interest.

When a total eclipse crossed over New England in 1932, researchers put out a call for people to share their wildlife observations probably the first study to intentionally track animals during an eclipse—people reported owls hooting, pigeons returning to roost, and a general pattern of bird behavior that suggested “fear, bewilderment, Purple Martins pausing their foraging and nighthawks flying in the afternoon. Whooping cranes dance shortly after the eclipse, and flamingos congregate. For many birds, it’s probably a once-in-a-lifetime experience.

A citizen scientist watched a yellow okra flower close during totality, just as it would at night—a favorite observation of Alison Young, co-director of the Center for Biodiversity and Community Science at the California Academy of Sciences and lead author of a paper describing the findings. The flower’s response was unexpected, she says in an email, since totality wasn’t very long.

During the 2017 eclipse, more than 600 observers submitted their findings to iNaturalist” a community science effort where observations described an absence of wildlife during the eclipse’s peak: busy bird feeders clearing out, insects going quiet, flowers closing up. Other community scientists noted bees quieting their buzzing in flower patches, zoo animals going through their nighttime routines, and Chimney Swifts swooping and twittering like it was dusk

The Eclipse Soundscapes project is also looking for observers to record and share “field notes” of the changes they see, hear, and feel during the eclipse, whether they’re in the total path or not. By going beyond the visuals, the Soundscapes team hopes to make the big day more accessible for blind or low-vision people who are often left out of astronomy, and to help everyone have a deeper experience of the rare event. “What we’re trying to do is have people be very mindful during the eclipse, and actually use all of their senses to determine what changes. Their resulting study found that as the moon started to cover up the sun, there was a drop in biological activity in the air—suggesting that day-flying birds and insects were coming down to rest.

Countrywide, people noticed swallows and swifts flocking as darkness fell. Frogs and crickets, common elements of an evening soundscape, started to call, while diurnal cicadas stopped making noise. Ants appeared to slow down or stop moving, and even domestic chickens responded—hens gathered together and got quiet, while roosters crowed.

Even in the partial zone, you can still pay attention to how nature responds—and contribute to science. Sending in your observations through a platform like iNaturalist or eBird can help provide valuable data for future research,

When I looked up at the cloudy sky on October 14, I was dismayed. I was so looking forward to watching the partial solar eclipse, predicted to be at its height at 80% in Cache Valley at 10:15. Now the sun was hidden behind heavy clouds. Refusing to give up all hope, I slipped my eclipse glasses into my pocket and headed up a hiking trail on the Wellsville mountains. At 10:10 I stopped on an open ledge, put the glasses on, and looked up into the sky.

I saw nothing but absolute, total black.

I waited a few minutes. I put the glasses back on.

This time I saw the darkness thinning. And behold! A golden croissant appeared in the black sky.

In very slow motion, the moon continued to slide across this glowing crescent, reducing it to a thin golden semi-circle.

It was spellbinding for me because this partial eclipse was so different from the 3 total eclipses I’d already seen. This time my attention was on the big black moon rock sailing slowly across a spot of light. In the past, watching a total eclipse was all about the sun disappearing.

My first eclipse was in 1961. My high school physics teacher had taken us on an all-night bus ride. In the morning, the bus pulled over in an olive grove. I will never forget how the color drained out of the countryside. The birds stopped singing. We felt the chill as the temperature dropped.

My second total eclipse was on a ship in the middle of the Atlantic Ocean. We were on course to intercept the path of totality when it started raining. The shop’s captain gunned the engines and somehow found a bit of open sky. We counted down: 3,2,1, Zero! The sun disappeared and the stars came out. We took off our glasses. We held our breath. And then a tiny spot of hot sun poked out on the the sun’s aurora, and what looked like a giant engagement ring spread across the sky.

My third eclipse was near the Grand Tetons in 2017. This time I was fascinated by the small crescents of sunlight shadows dancing across my shoes.

In ancient times, the temporary extinguishing of the sun caused quite a bit of fear. The Chinese thought a giant dragon was taking bites out of the sun. They beat drums to drive the dragon away. In other countries, warriors shot flaming arrows into the sky to reignite the lost fireball.

We still have much to learn about the moon, the sun, the stars, and beyond. But what I learned this year was that the sun is 400 times the size of the moon. The moon is 390 times closer to the earth. This allows the sun and moon to appear to us to be the about same size. So, when the moon slides between us and the sun, sometimes it covers it completely. But when the moon is at its farthest from the earth, it leaves the fiery edges of the sun exposed – the Ring of Fire.

It’s a math problem with moving parts, but mathematicians can predict exactly when the next total eclipse will be visible in North America.

Set your calendar for April 8, 2024.

“Some Tribes are allowed to view the eclipse while others, like the Navajo and Ute Indian Tribes, do not look at it. This can include reflections (water, mirrors, windows, etc.) or photos.

Please avoid posting videos or photos of the eclipse on social media – some Tribes are forbidden to look at the eclipse, including images and videos…”

Special Annual Event: Perseids Meteor Shower

The Perseids meteor shower is one of the most popular events of the year for sky watchers. A meteor shower is simply an increase in meteor activity which is produced when the Earth passes through a trail of debris that is also in orbit about the Sun.

Perseids debris comes from the Comet Swift-Tuttle, the largest object known to make repeated passes near the Earth. Its nucleus is about 6 miles across. Most of its meteoroids are the size of sand grains; a few are as big as peas or marbles. When they enter Earth’s atmosphere, they are called meteors. Almost none hit the ground, but if one does, it’s called a meteorite.

The Perseid shower is detectable from July 25-Aug 20, but meteor activity rises sharply around Aug. 12. For example, on the 25th you can expect to see a meteor every hour. Maybe 5 an hour by the 1st of August, up to 15 an hour by August 10th. But then on August 12, the number will spike to 50 -80 /hour and in some years up to 200! Then the number will quickly subside until Aug 20, when you’ll be back to 1 an hour.

Perseid meteoroids are fast. They enter Earth’s atmosphere at roughly 133,000 mph– or 60 km per second. They also make a sound! Fast-moving meteoroids ionize the air in their path leaving behind a trail that can briefly reflect radio wave from TV stations, RADAR facilities or AM/FM transmitters. A “radio meteor” is the short-lived echo of a radio signal that bounces off such a trail. Scientists at the NASA Marshall Space Flight Center in Huntsville, AL have established a radio meteor monitoring system. Here’s what a typical echo sounds like against some background static:

See NASA Radio Meteors: https://science.nasa.gov/search?search_api_views_text=radio+meteors (accessed August, 2021)

Hmmm… Kind of reminds me of a whale song.

This year, August 12th features a gibbous moon which means lunar glare will wipe out the path of the smaller meteroids . You’ll want to find a spot in the moonshade which will minimize glare. Or you can watch during predawn moonless hours on August 12th which will be the peak of this year’s show. No worries for those of us who can’t stay awake past midnight though. There will still be so-called shooting stars even while the moon is out—just less than when the moon has set. Furthermore, Jupiter is almost opposite to the sun with the planet coming physically closest to the Earth in its orbit . That means good viewing as Jupiter will appear very large. Look for it together with the moon in the constellation Sagittarius in the southeast sky. Depending upon your viewing equipment, you may be able to see some of Jupiter’s moons as well as the Great Red Spot, which is a gigantic hurricane-like storm twice the size of Earth on Jupiter’s surface.

For a sociable viewing experience, sky watchers in Northern Utah are invited to the Stokes Nature Center/American West Heritage Center Star Party August 12th from 9-1. We’ll have powerful telescopes, experienced interpreters, and all sorts of fun activities for adults and families. For more information see www.logannature.org or www.awhc.org

Dark Sky Parks

Chances are that if you step outside your front door at night and look up, you can get a pretty good view of the night sky. Even if you live in a bigger city or town, a short journey by car, bike, or foot can usually get you to some amazing stargazing places. And that’s because you live in a wonderfully wild place called Utah.

We are lucky to be able to experience natural darkness in so many places around Utah. Over 99% of all people in industrialized nations today live under light-polluted skies, and 2/3s of Americans can no longer see the Milky Way from their homes. But in Utah, we have the darkest skies on average out of any state in the lower 48, and the recognition for these pristine conditions has reached international levels. The world’s first dark sky park was designated right here in Utah at Natural Bridges National Monument. In fact, with 18 official certified dark sky places, Utah has the highest concentration Internationally recognized dark sky places in the entire world.

More and more, we are recognizing how important natural darkness is to our natural and human communities. Wildlife depends on natural darkness for their survival, and light pollution can interfere with reproduction, migration, and even predator avoidance for some wildlife species. For humans, increased light pollution can interrupt sleep patterns, interfere with immune responses, and increase risk for obesity. Naturally dark skies can contribute to positive experiences for people outdoors as well, like an experience of awe.

So next time you want to head outdoors to connect with natural world, consider going somewhere at night. If you want to visit a designated dark sky area, jump online and search “Utah dark sky parks” and plan a trip. Who knows? Maybe you will even get a better night sleep and reduce your stress.
