A few weeks ago I captured these images of wave clouds over the San Francisco Peaks. At first, there was a “short stack” of lenticular clouds, specifically Altocumulus Standing Lenticularis (ACSL).
I took several photographs looking toward the peaks from the Bonito Park area near the west entrance of Sunset Crater Volcano National Monument. I alternated between wide-angle shots showing the snow-covered flats and zoomed-in images of the stack of clouds. After a few minutes, I was ready to leave.
But before I did leave, new clouds began to form beneath the stack of ACSL. These clouds were quite different and appeared as long, wispy filaments or rope-like clouds. Again, I took photographs ranging from wide-angle shots to zoomed-in shots. After about 8–10 minutes the delicate filaments began to take on more of an ACSL shape similar to the already-present ACSL above.
I was intrigued by the shapes of these clouds so I posted a comment with photographs to a weather discussion group with many atmospheric scientists far more aware of the dynamics and details of wave clouds than I. It turned into a fascinating discussion with links to journal articles, modeling studies and, inevitably, YouTube.
I do not think we reached a consensus on the dynamics and evolution of these cloud filaments but all agreed it was a worthwhile discussion.
The comet continues to rise higher in the northwestern sky after sunset. It is now in a position so that I can get reflections of the comet in water at the same time that the comet is above the San Francisco Peaks. So I worked out the geometry and set up on Ashurst Lake, southeast of Flagstaff.
It didn’t work out for a couple of reasons. There was too much wind and the surface of the water remained ruffled rather than smooth. And then, as the comet was sinking lower in the sky and the winds began to diminsh clouds developed.
So, I’ll have to try this one again when I get better conditions.
The comet is now visible in the evening sky but also remains visible in the morning sky. Evening twilight is bright enough to make it difficult to see the comet without binoculars or long exposures on a camera. That will change quickly as the comet moves higher in the northwestern sky in the coming days and weeks.
Above is an image of the comet in the evening sky. Layers of clouds and moisture threatened to interfere but actually made the photograph more interesting with saturated twilight colors.
This image is a stack of ten images each 4 secs exposure at ISO 1600, ƒ/1.8, and 85mm focal length. The individual images were stacked using Starry Landscape Stacker.
A winter storm brought snow, clouds, and fog to some of my favorite photographic locations. The early morning sun lights up a band of clouds that encircles the San Francisco Peak. Below the peaks, fog lies in the low areas of both Upper and Lower Lake Mary.
A smaller area of fog sits in the corner of the Mormon Lake basin and partially obscures some of the old ranch buildings.
Finally, a small patch of grass pokes up from the still water of Lake Mary while fog blurs the background.
Over the past couple of years I have tried to get good photographs of the Moon rising over the San Francisco Peaks. A good time of year for this is January when the nearly full Moon rises in the northeast. Then find a place along old Route 66 in Brannigan Park and get your shot. It works best if there is fresh snow on the peaks but sometimes you just have to take what you get.
And here are some images from 2015 which was the first time I tried shooting from this location.
Sometimes the first photograph you take of a place is the best. I’ll keep trying.
