Fall (or autumn, if you prefer) is over in northern Arizona. Peak fall colors started high on the peaks back in September and have been working their way down to lower elevations. The peak moved through Oak Creek Canyon in mid November.
A few years ago and saw this little guy sitting at the base of the tree on the North Wilson Trail. He was still there on this year’s hike but was starting to lean over a bit so we set him upright. Never know what you’ll find on a hike.
The Waterline Road in the San Francisco Peaks reopened in October. It had been closed for more than two years in the aftermath of the Pipeline Fire. That fire occurred in the same area as the Schultz Fire (2010) and managed to burn what had been spared by the earlier fire. After two years of work, the Waterline Road was safe for the general public to use again.
We rode our mountain bikes up the road and were saddened–but not surprised–by the destruction of the fire. There had been a lot of new growth after the 2010 fire–especially with new aspen trees already attaining heights of 10 to 20 feet. All this burned in 2022. Once again, new growth is taking place but most of it is still quite small.
The Inner Basin, however, was mostly spared by the 2022 fire and here were many aspen trees in full autumn colors. Along the road there are a few locations where you can get a wider view of the trees and the mountains but mostly the only view along the road…is the road.
A previous post showed many images of Comet C/2023 A3 (Tsuchinshan-ATLAS) taken when the comet was visible in the morning sky. The comet then moved between the Earth and Sun making it difficult to see. A period of 10 days passed between my last morning images and my first evening images.
At first, the comet was difficult to see in the bright evening twilight and the presence of the Moon made it even more difficult. But each day the Moon rose later in the evening and the comet rose higher in the western sky. I was able to take advantage of clear skies and shot photographs on eight days. Here are some of the best photographs from those sessions.

I had already shot images of the comet while looking to the east across Ashurst Lake when it was a morning object. Now it was time to shoot looking to the west across the Lake. The comet was very bright and easy to see. I also shot a long sequence of images to create a time-lapse video of the comet setting in the west.

The next evening I set up at the Arizona Snowbowl parking area–along with dozens of other comet watchers. It was fun to listen to folks admiring the comet and the joy from the kids when they were first able to spot it in the darkening sky. The anti tail was even easier to see on this night compared to the previous evening.

The Moon was still a factor in the evenings but the comet was getting higher in the sky so it balanced out. On this evening I went to The Narrows at Upper Lake Mary since that section of the lake is oriented WSW-ENE. This meant I could photograph the comet above the water and get a reflection of it in the water. That worked out pretty well.

A few days of clouds shut me down but by this day it was very clear and the Moon was no longer a problem. I opted to use a longer telephoto (180mm) for these shots even though it might truncate part of the tail. The anti tail is still visible but is much less striking than in earlier days.

The comet was continuing to rise higher in the western sky and was closer to the Milky Way so I switched back to ultra-wide angle lenses to capture both. Bonus: I was able to again capture the comet and tail reflected in the waters of Lake Mary. For the very wide image shown here I did a composite. The first image had star tracking turned on to get sharp stars and comet; the second image had tracking off to get sharp foreground. These were then combined and blended in software.

The comet continued to climb higher, become dimmer, and have a shorter tail as it moved away from Earth and Sun. I switched to a short telephoto (85mm) to shoot a sequence of images which were then stacked to reduce image noise. I was also able to use the sequence to create a short time-lapse video to show the movement of the comet over a period of about 45 minutes.

As the comet climbed higher it also was closer to the Milky Way and I again tried to get a shot with both features. This was taken with at 35mm focal length.
31 October 2024
As the comet retreats it is getting smaller in the sky and it is better to use medium length telephoto lenses. Here is an image taken with the Nikkor 180mm ED AI-S lens, a legacy, manual focus lens.
What’s next?
We are once again in a period of clouds. When skies are once again clear the comet will be much farther away, smaller, and dimmer. At this point, it will require longer exposures and bigger telephoto lenses. It should be fun!
Storms in August were more plentiful than in July although there were still some extended breaks in the monsoon. Rainbows remained elusive for me. I was able to photograph a few that displayed short segments but I never captured a full rainbow. Lightning, on the other hand, was plentiful and I did well in that genre.
Here is a partial summary of August monsoon photography.

Mormon Lake Overlook is a short drive from Flagstaff and affords an amazing 360° view. This was one of the many days with only a partial rainbow but the juxtaposition of the rainbow and the tree in the grasslands of Anderson Mesa was a pleasing composition. A few minutes later the Sun beautifully illuminated some light rain falling from a dissipating thunderstorm. The color was intense and only lasted a few minutes.
Using The Photographers Ephemeris I realized I could photograph the rising Moon looking down the length of Upper Lake Mary from the Narrows picnic area. Arriving early I was able to shoot several photographs of the distant clouds (more on that later) reflected in the calm water. By using a 5-stop neutral density filter (ND) I took long exposures (2-6 seconds) which had the effect of smoothing the surface of the water.
So what about those clouds? There was a dissipating cumulus congestus cloud to the east but also some anvil clouds from distant thunderstorms in eastern Arizona. Would there be a gap in the clouds? Would I be able to see the Moon? Yes, there was; yes, I did.
As the Moon barely cleared the top of some distant clouds it cast a long reflection on the lake. Because there was only a very small bit of Moon showing the reflection had very sharp edges. As the Moon rose higher and more of it showed the reflection became wider and had less distinct edges. Even more interesting, the Moon was causing parts of the distant clouds to glow and these also cast light reflections on the water. It was very interesting and beautiful. And it only lasted a few minutes as the Moon rose higher and was obscured by the distant clouds.
