The waxing Moon is getting brighter in the evening sky and this makes it more difficult to see Comet C/2020 F3 (NEOWISE). In fact, I was unable to see it with the unaided eye but both binoculars and long-exposure photographs easily brought out the comet.
On the other hand, the presence of the first-quarter Moon illuminates the inner canyon while the comet is faintly visible above.
The image is a composite. The first image is on a fixed tripod to get a sharp result of the moonlit canyon. The second image is on a tracker to get sharp points for the stars and comet. The two images are then combined. Camera settings are 24mm, ƒ/4, 120 seconds, ISO 400.
As a bonus, a late evening thunderstorm developed just west of Page and moved to the northeast while producing a lot of lightning. Although no cloud-to-ground strokes were noted, the lightning easily illuminated the cloud from the inside.
Comet C/2020 F3 (NEOWISE) remains visible in the northwest sky after sunset. It is slowly diminishing in brightness (current estimated magnitude of +2.8) and the waxing crescent Moon is making it harder to see the fainter portions of the tail.
These images overlook Grand Canyon and show the comet above the North Rim and Kaibab Plateau.
A recently discovered comet is now shining brightly in the morning sky. Comet C/2020 F3 (NEOWISE) was first spotted March 27, 2020, by NASA’s NEOWISE space-borne telescope. The comet passed inside Mercury’s orbit on 03 July 2020 and quickly brightened as it as heated by the intensity of the Sun.
The comet has been rising around the start of Astronomical Twilight when the eastern horizon is just beginning to brighten. Within about 45 minutes to an hour—or shortly after the start of Nautical Twilight—the morning sky has become bright enough to make observation difficult.
The image above was taken as the comet rose above Grand Canyon. Also visible in the image are the planet Venus, the bright star Aldebaran, and the Hyades and Pleiades star clusters.
By the third week middle of July the comet will shift from the morning sky into the evening twilight sky. Again, there will be a short window of time in which it is easily observed but viewing the evening is far easier than the morning.
National Parks, that is. Here are several photographs taken this winter in the National Parks and Monuments that are in northern Arizona.
These two images were taken shortly after sunrise at Wukoki Pueblo in Wupatki National Monument. A recent snowstorm had brought snow to lower elevations and I was hoping there would be some snow at this location. No snow but the sunrise was still pretty nice.
Later that morning in Sunset Crater National Monument, where there was new snow, a small amount of snow on the namesake crater helping to reveal its subtle textures.
The next two images are from Grand Canyon National Park at sunrise. A recent minor storm had left some low clouds and fog in the lowest reaches of the canyon. As the sun rose higher and the canyon walls warmed the fog was lifted up and out of the canyon producing some eye-level clouds for a brief moment.
Finally, we have a panorama of the rising nearly-full Moon in late afternoon. Wonderful!
It’s been an unusual monsoon season across Arizona this year. After both a wet winter and wet spring—with above normal precipitation amounts all the way into the month of May—things went dry. The North American Monsoon started late this year with the first significant rainfall not arriving until the second half of July. This was unfortunate as the dryness partially contributed to a very damaging wildfire (Museum Fire) burning across portions of the San Francisco Peaks.
Just a few days later, the rains finally arrived. And, then, they stopped again. And it has been that way much of this monsoon season. A few days of rain, then a week or more of dry weather. A normal pattern would have rain falling perhaps four days out of seven for a two-month period. Folks around here have dubbed this monsoon the “nonsoon”.
And, of course, with the lack of moisture and thunderstorms opportunities for photographing storms, heavy rain, lightning, and sunsets has been a challenge. But it only takes one great photograph to make it a successful season. I’m still trying to get that photograph.
Here are some of the more interesting photographs from this “nonsoon monsoon” season.
