A New Cholla Cactus in 3D

Sometime last year, we noticed a small protrusion of what appeared to be new cactus growth under the red rocks that cover the ground around our house. Eventually, this winter, the cactus had evolved into a two-prong sprout with each prong measuring six to eight inches in length. As of the emergence of spring, the growth has really taken off virtually tripling the size of the little cactus.

I took a side-by-side image of the cactus and made it into the anaglyph seen above. Click on the image to enlarge.

Solar Astrophotography

In anticipation of the Annular Solar Eclipse on October 14, 2023, I got out the Canon SL1 camera and associated accessories to photograph the solar disk. I used the Canon EF 100-400mm along with a Thousand Oaks Optical threaded SolarLite® filter to get the (clickable) image above. I had to experiment with the camera settings to get the image and further had to adjust it using a photo processing app.

The setup resolved the solar disk and a couple or three sunspots currently visible; the two larger sunspot visible are 3297 and below that 3294. Those numbers are according to SpaceWeather.com.

As I mentioned above, I had to experiment with the camera settings a bit. Using the camera’s Programmed (P) setting, the images were overexposed. I switched to the shutter speed priority setting and tried several exposure times from 1/1000 second, 1/2000 second, and 1/4000 second. The latter, which is the fastest shutter speed on the camera, captured enough of the details needed to produce the image seen above and will certainly be good enough for the annular eclipse. For the total eclipse in April of 2024, it will be necessary to remove the attenuating filter during totality in order to capture the details of the solar limb and the spectacular appearance of the solar corona.

Lenticular Clouds and a Flower

The Wickenburg and surrounding area forecast called for high winds (to 40 MPH) all day today. In the sky (clickable image above) we saw several areas like the one depicted having lenticular (altocumulus lenticularis) or lens-shaped clouds. Sometimes called “standing lenticulars,” the clouds appear stationary in the sky but the truth is they are in a very high winds condition usually downwind from mountain ridges. The clouds condense at the tops of the “mountain wave” where the airmass is rising and descending as it moves away from the ridge, I think they are very pretty to look at, but I wouldn’t care to be in an aircraft anywhere near them.

In other news, we had an Argentine Giant Cactus flower opening up on Palm Sunday evening. The photo below is that flower in the broad daylight of Monday afternoon. Click on either image to enlarge.

Photo Update

It’s been eleven months since we did a photo update. Here we are in the courtyard enjoying a nice spring day with the temperature up to about 72° with an expected high of 76°.

Today, we’re going to grill up a couple of Filet Mignon steaks and Verna will fix a nice salad to go with the meal. Yes, the dogs will be getting some of the scraps.

Vernal Equinox 2023

OK — the first day of Spring and the Equinox are here. The nights of darkness and days of sunlight are of equal lengths, according to the official astronomical ephemeris. However, at our particular latitude and longitude here in Arizona, the day length grew to just over twelve hours last Wednesday per the actual observed sunrise to sunset times. So, we can look forward to longer days peaking at the Summer Solstice and then on to the Fall Equinox when they fall back to be less than 12 hours again.

As of a couple of weeks ago, the Turkey Buzzards have begun to migrate back to Arizona and other northern places, I assume. These vultures bring the promise of warmer conditions for us, although there is still some cooler weather and precipitation still headed our way.

Even though it will be a month or more before the Pride of Barbados or Red Bird of Paradise shrubs to return from their winter slumber (we cut them back to nearly ground level in the fall). We expect that the hummers will begin to take advantage of the nectar when the gorgeous flowers return to our courtyard.

Enjoy the warmer weather and longer daylight. We know we will be enjoying the spring weather, birds and flowers.
