Light Pollution in the Southwest

For those of us who are stargazers that love to look up at night, one of our primary concerns is anthropogenic illumination, a.k.a Light Pollution. Damsel and I remember one night in southwestern Utah at Zion National Park when we looked up to see so many stars that it was difficult to discern any of the major constellations since the sky was virtually filled with visible stars. Zion is remote enough that lights from major population areas are far over the horizon, thus providing a memorable and overwhelming view of the stars and galaxies in God’s wonderful universe.

Here in Wickenburg, we have fairly dark skies, but depending upon the time of night, we still have a little light pollution that interferes with our stargazing. However, just sixty miles southeast of here is the giant megalopolis of Phoenix and surrounding cities that don’t give a hoot about dark skies. As a result of that, our views in the direction of the Valley are clouded by that massive amount of candlepower.

Referring to the image above, Wickenburg is in the approximate center of the image on the border of Maricopa (south) and Yavapai (north) counties — you can see our little light blob just at the west end of the “notch” in the north side of Maricopa County. The giant light blob to the southeast of our town is the afore-mentioned megalopolis. You can see how their pollution might affect the dark skies of our area.

About the images on this page: due to a fluke in the GOES Southwest USA Imagery, I captured these nighttime images without the normally present clouds and other observed phenomena. These are the pre-programmed night images sans the clouds. The image at the top is cropped to show our area while the image below is the entire background for the GOES Southern Rockies nighttime view.

Spring Equinox 20 March 2025

Happy first day of Spring (northern hemisphere)! We’re off to a good start with daytime temperatures in the mid 70s and forecast to become in the mid 90’s in a week or so.

Greeting me on the first day of spring were these two critters — a cactus wren on the block feeder and an antelope ground squirrel foraging in the west side of the yard:

We always get a lot of comfort and enjoyment when the creatures which abound in our little corner of the desert show themselves to us and our cameras.

Both images were taken with the Canon EOS Rebel SL3 and an EF 55-250 lens at 250mm. Click on either image to view enlarged.

Washington’s Birthday

We still honor the Father of the Country, George Washington, on the Anniversary of his birth, February 22nd. The following is edited from our post of Washington’s Birthday back in 2010.


Today is the anniversary of the birth of George Washington, the first president of the United States, and the Commander-in-Chief of the Continental Army during the Revolutionary War.

From WikiPedia:

gw.jpgGeorge Washington (February 22, 1732 – December 14, 1799) served as the first President of the United States from 1789 to 1797 and as the commander of the Continental Army in the American Revolutionary War from 1775 to 1783. Because of his significant role in the revolution and in the formation of the United States, he is often referred to as “Father of His Country”.

The Continental Congress appointed Washington commander-in-chief of the American revolutionary forces in 1775. The following year, he forced the British out of Boston, lost New York City, and crossed the Delaware River in New Jersey, defeating the surprised enemy units later that year. Because of his strategy, Revolutionary forces captured the two main British combat armies at Saratoga and Yorktown. Negotiating with Congress, the colonial states, and French allies, he held together a tenuous army and a fragile nation amid the threats of disintegration and failure. Following the end of the war in 1783, King George III asked what Washington would do next and was told of rumors that he’d return to his farm; this prompted the king to state, “If he does that, he will be the greatest man in the world.” Washington did return to private life and retired to his plantation at Mount Vernon.

For those who still recognize this day in honor of our first president, have a very Happy Washington’s Birthday!

Spring Song

This 10 second video is of a Curve-Billed Thrasher singing what sounds like a mating call. It’s not the usual loud “weee-weet-tweet” that we hear during other times of the year. Could it be that we’re getting an early spring about four weeks ahead of schedule? The forecast for our part of Arizona calls for 80° temperatures by the weekend.

AS you can see from the video, holding the camera steady at 250mm zoom is difficult without a bi- or tripod. I made this video today with my Canon EOS Rebel SL3 and the EF 55-250mm lens. I am still experimenting with and getting used to making videos with the Canon camera.

Finches

This is a photo of one of the Nyjer Seed feeders in the back yard intended to attract Finches. You can see it was doing its job this morning when I snapped the photo.

On the left side of the feeder (stage right) is a House Finch, the male of the species. House Finches are commonly seen throughout the U.S. and Mexico, with some excursions north of the U.S. border.

The smaller Lesser Goldfinches are seen on the right and bottom of the feeder. This variety of Goldfinch ranges across much of the Southwest U.S. and Mexico. They seem to be permanent residents here in the Sonoran Deserts of Arizona.

Both species of finch like to snack on the Nyjer seeds. The oily content of the seeds seems to be nutritious for the birds. We buy Nyjer seeds for the Finches and a mixed seed variety for the other birds that hang out here. Nyjer is quite a bit more expensive than the other seed mixes, but we think it is worth the investment in order to keep the finches coming around.

Revival of the Compost Bin

In the post on Imbolc Weekend, I mentioned that our compost bin needed rejuvenation by virtue of a new bag of worms. I ordered 500 wrigglers from Uncle Jim’s Worm Farm at that time; today, the worms arrived and I followed the recommended instructions to introduce them to the heap within the bin. I assume that they are happily getting busy with their program of converting our compost items into vermicast.

When we replaced our old compost bin with this one, I predicted that it, also, wouldn’t last very long in Arizona, like it’s predecessor, but it has hung in there for nearly 10 years now. Here’s a photo of the bin then and now:

As you can see, the lid is a little warped and needs to be secured with a bungee, but the ol’ bin is still doing its job of keeping the compost heap, worms, castings and soil contained within.

Cardinalis Cardinalis

I took my Canon EOS Rebel SL3 camera with me on my morning walk, when this Cardinal lit atop the anti-squirrel cone on the bird feeder crook. Zoom lens set to 250mm in the camera’s “program” mode, which is the setting for automatically adjusting aperture, shutter speed and ISO speed. Clickable image.

It is a nice, sunny morning here with temperatures in the 50s F. The forecast is for possible rain over night and for the next few days. We need it.

UPDATE: [02/05/25] In the interest of being fair and balanced, I took an image of the Female of the Cardinalis species in a mesquite tree out back near the birdfeeders. Click to open the image viewer.
