October and November brings color to the foliage in northern Arizona. This year, however, the colors have been subdued and the color change has been over an extended period of time rather than a sharp peak. Nonetheless, it’s always a fun time to get out and photograph. These photographs were taken between October 10 and November 1.

The color continues to migrate into the lower elevations. Middle and lower sections of Oak Creek Canyon have yet to hit their peak.
As mentioned in an earlier post the monsoon had a late start this year–and ended about the middle of September which is fairly typical.

I went to Grand Canyon early and was photographing storms shortly before 3 P.M. It was interesting and unusual because fog rapidly developed deep inside the canyon as the storms approached from the south. For a moment I wasn’t certain I would see anything in the reduced visibility. But close lightning bolts dropped from the cloud base above, through the clear air, and then disappeared in the fog in the inner canyon. It was really spectacular to see this.
Another storm dropped a lightning bolt into the canyon near Desert View Tower with multiple contact points. Wow!

And then the rainbows arrived with some brilliant and colorful arcs of light over Desert View point. Finally, just moments before sunset, another rainbow stretched from the North Rim to the South Rim.
It was an amazing day.

An early evening storm produced a lot of in-cloud lightning that lit up the thunderstorm at the same time that the setting Sun was illuminating it from the West. And all of this was reflected in the waters of Mormon Lake.

Storms were more isolated this day allowing for nice views of the convection. I was able to get several photographs of the storms over the Little Colorado River (LCR) valley as I was heading towards Grand Canyon. Late in the afternoon a short segment of a rainbow appeared over the LCR.

I spent the late afternoon and early evening in Wupatki National Monument and was able to get some really great sunset photographs. There was lightning after dark but most of it was too far away for interesting structure and branching.

Late afternoon and early evening storms were present to the west of Mormon Lake. I kept hoping for some dramatic lightning with sunset color–but only got the latter. It was still pretty good!

I was actually trying to photograph Comet C/2023 P1 Nishimura but these clouds were in the way. This was taken well after sunset and the color was pretty remarkable.

So after a late start the monsoon season produced many photogenic opportunities for clouds, sunsets, fog, and lightning. And now the long wait until next season.

It may not have been a total eclipse but the annular eclipse was still wonderful to experience.
Sequence of images of the eclipse from C1 through C4, including the annularity or “Ring of Fire.” The images are not evenly spaced in time but instead concentrate on the few moments before, during, and after the annularity of the eclipse. Beginning of the eclipse at lower left; the end at upper right.We were close to the center line in the small town of Fillmore, Utah. Before the sun even rose that morning we drove the few blocks from our hotel to Fillmore City Park and set up gear and chairs on the grassy field along with many others. Then it was time to wait and chat with all the other people.
I shot the eclipse with three cameras. My main rig was a Nikon D750 with the Nikkor 200-500mm f/5.6E lens set to 500mm. The camera and lens was attached to an iOptron SkyTracker so that the camera would follow the Sun without my having to make adjustments. A Kendrick Astro Solar Filter covered the front of the lens. I shot a sequence with 5-minute intervals until a few minutes before and after annularity; during this most interesting part of the eclipse I shot using 3-second intervals.
The secondary setup was with a Sony RX10 set to 35mm focal length and 1-minute sequences from beginning to near the end. The battery failed late in the session and after replacing it the focus was slightly off (operator error!).
And the third camera was an Apple iPhone SE3 which I used to shoot scenes around us in the park.

[Sony RX10]There were some ooh’s and aah’s as the eclipse started (C1–first contact). But when C2 occurred (second contact) there was cheering and applause. The end of annularity (C3–third contact) brought another round of cheering and applause. There was little crowd response at C4 (fourth contact–end of eclipse) since most folks had already left. The only folks still there were those dedicated to capturing a sequence of the entirety of the eclipse.

Crowds and traffic had lessened considerably by the time we left and we drove back to Flagstaff with a stop for an early dinner in Kanab, Utah.

But, wait! There’s more.
The day before the eclipse we were able to see a spectacular halo as were were driving through Utah. At various times we saw the 22° halo (the most common halo), supralateral arc, parhelia (also known as “sun dogs”), parhelic arc, upper tangent arc, and circumzenithal arc.

A few days ago we had a cold front move across the area and overnight temperatures fell below freezing for a few hours in the higher terrain. It turns out that October is a good month for fog formation from these first frontal incursions. Area lakes still have relatively warm water from the recently ended summer. The passage of the cold air over the warm water allows for increased moisture flux from the warm water into the colder air that increases the dewpoint (and relative humidity) and can result in fog. Also, the shorter days–and longer nights–allows radiation fog to develop in the valleys.

With that in mind, I found myself driving past Lake Mary to Mormon Lake before sunrise on Tuesday morning. As I approached Lake Mary visibility dropped quickly to 1/4 mile, then 1/8 mile, and then 1/16 mile. Visibility improved once I passed both Lower and Upper Lake Mary. At Mormon Lake, there was fog swirling in the basin and the rising Sun was just starting to illuminate the summits of the San Francisco Peaks.

After the fog dissipated in Mormon Lake, I returned to Lake Mary where the fog was still present and I was able to capture fogbows plus a nice photo of a sailboat anchored in the lake.

(1) Steam fog (arctic sea smoke). Steam fog forms when water vapor is added to air that is much colder, then condenses into fog. It is commonly seen as wisps of vapor emanating from the surface of water. This fog is most common in middle latitudes near lakes and rivers during autumn and early winter, when waters are still warm and colder air masses prevail.
(2) Radiation fog (ground or valley fog). Radiational cooling produces this type of fog. Under stable nighttime conditions, long-wave radiation is emitted by the ground; this cools the ground, which causes a temperature inversion. In turn, moist air near the ground cools to its dew point. Depending upon ground moisture content, moisture may evaporate into the air, raising the dew point of this stable layer, accelerating radiation fog formation.
In a previous post I wrote how the North American Monsoon (NAM) was very late getting started in July. Fortunately, once started, it resulted in normal precipitation amounts for the month of August. Here are photographs and discussion of some of the events during the month.
