Lunar Halo Above Evia, Greece

February 01, 2021

Moon Halo 2020-11-28

Photographer: Dimitris Malliaris
Summary Authors: Dimitris Malliaris; Jim Foster
Quite often I’m able to photograph interesting atmospheric phenomena
from the backyard of my house in the central Evia region of Greece. In
late November 2020, the lunar halo shown above appeared a few hours
after nightfall. As with their daytime counterparts ( solar halos),
pencil-shaped, hexagonal ice crystals that compose cirrus
clouds, and are more or less randomly oriented as they fall, are
responsible for the ring that encircles the Moon

Note that to the left of the Moon (between the Moon and the halo) the
open star cluster called the Pleiades, also known as the Seven
Sisters, can be seen. Photo taken on November 28, 2020, at 20:59.
Photo Details: Canon EOS 6D camera; Canon 24-105mm f/4 L IS USM lens;
24mm focal length; ƒ/5 aperture;; 10 sec. exposure time; ISO:800; Adobe
Photoshop CC (Windows).

Orion, Geminid Meteors and Oxena River Waterfall

March 01, 2021

Geminidi and Orione Above the Oxena River Falls - The Continuous
Flow of Energy of the Universe LD

Photographer: Dario Giannobile
Summary Authors: Dario Giannobile; Jim Foster

Shown above is majestic Orion, which when it breaks the horizon in
fall, is perhaps the most attention-getting constellation.
Betelgeuse and Rigel hold court on opposing ends of the Great
Hunter. The orange color of the cold star Betelgeuse and the blue of
the hot Rigel makes them easy to identify. On clear nights in dark
locations, a hint of color can be even perceived in the Orion
Nebula. Note that the celestial equator passes near Orion’s
Belt, so Orion dominates the night sky in both the Northern and the
Southern Hemisphere.

On this long exposure image, the flow of the Oxena River in Sicily,
Italy, as it plunges over a volcanic caprock, is aslant to the
paths of the Geminid meteors. Photo taken on December 13, 2020.

Lunar Mirage and Cruise Ship

April 01, 2021

Nave-con-falce-di-luna2

Photographer: Marco Meniero
Summary Authors: Marco Meniero; Jim Foster

Shown above is a lunar pedestal that resulted from a lunar mirage
( Etruscan Vase or omega mirage) observed over the
Tyrrhenian Sea, near Rome, Italy. It’s juxtaposed here with a gayly
painted cruise ship. Mirages such as this are caused by atmospheric
refraction that occurs when light traverses an unusually warm layer of
air lying immediately above the sea surface. In order to view these
sorts of distortions, however, the temperature variation from the
surface of the sea to a level perhaps 50 ft (15 m) or so above it must
be quite remarkable. If you look closely you can also detect
earthshine. Photo taken on January 17, 2021.

Photo Details: Eos 1DxmK2 camera; Canon EF 400 lens; 2..8 + 1.4X;
equivalent focal is 900.

Archive - Ridge Line Induced Crepuscular Rays

July 31, 2021

6a0105371bb32c970b0134883230c8970c Every weekend we present a
notable item from our archives. This EPOD was originally published
October 19, 2010.

Photographer: Piero Armando

Summary Author: Piero Armando; Jim Foster

With a fantastic view of the Italian Alps just to the west of where
I live, I'm fortunate enough to enjoy many splendid sunsets. The
photo above lacks the fine colors that results from many such sunsets
but displays an impressive array of crepuscular rays. Since the sky
is free of cumulus turrets that often are responsible for rays,
they must form in another way. In fact, these rays are due to natural
gaps and prominences along the ridge line as well as the presence of
dust and haze in the lower atmosphere. These aerosols are very
effective in scattering sunlight. It's easy to see just where
sunlight is blocked (spurs) and allowed to stream through (notches).
Photo taken on September 1, 2010.

Photo details: Canon EOS 30D camera; manual mode; 1/1000 second
exposure; F7.1; focal length of 180 mm; image cropped.

Thunderstorm at Sunrise in Canyonlands National Park

October 01, 2021

Photographer: Enrique Noriega
Summary Authors: Enrique Noriega; Jim Foster

Shown above is a distant thunderstorm as viewed at sunrise through
Mesa Arch in Canyonlands National Park, Utah. A relatively easy
walk, Mesa Arch is just ½ mile (0.8 km) from the visitor’s
parking area. This striking arch took shape when water pooled and
eventually eroded through bedrock, composed of Navajo sandstone, at
the edge of the mesa. Photo taken on August 26, 2021
