Summary Author: Meiying Lee

During the total lunar eclipse of November 8, 2022, which was
observed here in Taiwan just after nightfall, a lunar
occultation of Uranus was underway at the same time as the eclipse, as
shown above. This rare celestial treat could only be seen in parts of
Asia and North America and was only visible through binoculars or a
telescope.

Glacial Striations in Victoria, British Columbia

November 25, 2022

Summary Author: Joe LaCour

Just a few hundred meters southeast and across the street from where
the Coho ferry docks in downtown Victoria, British Columbia,
you can see a great example of the power of the glaciers from a
previous ice age. Some 15,000 years ago, a glacier flowed over what
is now Victoria. The surface of the outcrop shown above was
grooved, scratched, and polished by the cutting action of pebbles
and boulders dragged along like a piece of giant sandpaper frozen to
the bottom a glacier. This fascinating ice age relic might be easy to
miss as the attention of many passers-by is captured by the striking
Legislative Parliament Building (not in photo). Note that the
bronze plaque in the foreground - Glacial Grooves and Striations
- acknowledges Victoria's glacial history.

Total Lunar Eclipse of May 15/16, 2022

September 26, 2022

Photographer: Howard L. Cohen
Summary Author: Howard L. Cohen
The total lunar eclipse of May 15/16, 2022 was extraordinary as it
was not only visible over most of the Americas but also its duration of
totality lasted about 85 minutes. In addition, the Moon was at perigee
and thus a Supermoon. Unfortunately, cloudy weather occurred over
some areas, including my location in north Florida. In fact, rain,
lightning, and thunder during the early evening delayed me from setting
up my telescope and camera. However, skies started clearing by 9:00
p.m. local time, allowing the first good views during the ongoing
penumbral portion of the eclipse. Though clouds now and then hid
the Moon, I still managed to assemble a number of useful images for
this eclipse composite.

Two Types of Bewildering Sunset Mirages

October 26, 2022

Summary Author: Mila Zinkova

Have you ever seen a sun that just doesn’t want to set? Well, on
September 4, 2022, I did, over the Pacific Ocean near San Francisco. Of
course, the sun set at the time it should have. I was watching
miraged images of the sun and, believe me, this miraged sun was in
no hurry to set. A few times, miraged images of the sun appeared at the
same level they disappeared from a few minutes before, giving an
appearance of the rising, rather than the setting sun. And then, for a
few minutes the miraged sun hardly changed or moved at all. It was as
if the world suddenly stood still. Actually, I was observing a
beautiful Novaya Zemlya sunset mirage. The photo at top is a
screenshot from a video I filmed. Click here to see it.

On the very next day, September 5, 2022, during a heat wave in
California, I filmed another confounding sunset mirage (bottom photo).
Click here to see the video. The atmospheric optics are quite
complex. Because sometimes the density differences of the air are so
great, rays become almost trapped within the air layers. This is
referred to as ducting. It may take some time and large distances
before the rays can escape these layers. Dr. Andrew Young helped
interpret this odd sunset.

"It starts out looking like a fairly typical leaky-duct sunset, with a
moderate amount of wave modulation within the duct ( inversion
layer). But then at the end, you do indeed have a blank strip that
fails to close up; the Sun simply fades away in the extinction
( loss of light in the atmosphere)."

In the video, you'll notice a green-flash bit or two in the early
part of the display, before the Sun dips down into the really thick
part of the extinction.

Dr. Young continues, "As always in these extreme Type B sunsets,
the path length of the rays through the air becomes longer and
longer as the Sun's geometric position goes farther below the
astronomical horizon."

Mirages such as this can be confusing to try to understand, but they're
a joy to behold.
