Crepuscular Rays Observed from Italian Alps

December 30, 2022


Tramonto sull'Aiguille Noire de Peuterey

Summary Authors: Valter Luna; Jim Foster

Shown above is a breathtaking set of crepuscular rays that I
observed over the Aiguille Noire de Peuterey in the Italian Alps.
Rays such as this while most often associated with clouds near the
horizon can also take shape when sunlight filters through mountain
passes, as was the case on this mid-summer’s evening. However, for
these rays to be seen, the atmosphere must be dusty. Sunlight
scattered by dust particles, and or other aerosols suspended in
the atmosphere, act to project the rays across the sky. Photo taken on
July 29, 2022.

Photo details: Nikon D100 camera; Sigma lens 18-250 mm (18 mm); 1/250

Though Saturn (top photo) is a wonderful target for backyard
astronomers, particularly when its ring system is favorably oriented,
as it has been the past several years, Uranus (bottom photo)
appears as little more than a blue dot, even when observed through a
10-inch (25 cm) telescope. This is because Uranus (7^th planet from the
Sun) is approximately twice as far from us as Saturn (6^th planet from
the Sun) and is less than half its size. Furthermore, it lacks a
conspicuous ring system and stratified atmosphere, so compared
to Jupiter and Saturn it’s rather indistinct. Nonetheless, it's still
fun to be able to observe through a telescope or binoculars. Photos
taken from St. Petersburg, Florida on November 14, 2022.

Sun Pillar Observed at Sunrise and Sunset from Sugarcreek, Ohio

Luck was with me throughout the daylight hours of December 20, 2022.
From my home in Sugarcreek, Ohio, not only was I fortunate enough to
observe a sun pillar accompany the rising Sun (top photo), but I
saw another pillar as the Sun was setting (bottom photo).

A sun pillar is a reflection phenomenon that results when
atmospheric ice crystals are in the vicinity of the Sun as it’s
rising or setting. But to be able to be viewed as a shaft of light that
piques one’s interest, these crystals have to be tipped ever so
slightly in our direction so that sunlight reflects off of them and
toward our eyes. It’s up to us to, well, just look up.
