Circles and Lines in the Dawn Sky
Cloud hid Comet Catalina but added a halo around the waning Moon, intersected by the line of the ecliptic.
I’m in Arizona, just inside the state line with New Mexico, on a quest to shoot Comet Catalina at dawn. Clouds prevented any view of the faint comet this morning but provided a fine consolation prize.
The waning crescent Moon was surrounded by an ice crystal halo, a rare sight around a thin Moon. The Moon was between Mars and Jupiter, heading toward a conjunction with Venus, below, on December 7.
The line of Venus, Mars, the Moon, and Jupiter, plus the stars Spica and Regulus defined the line of the ecliptic beautifully in the pre-dawn sky.
It was a show of circles and lines, real and imagined, in the morning sky.
With luck, clouds will clear to reveal Comet Catalina, which is likely fainter and less spectacular than hoped. But such is the way of comets. Regardless of what the comet does, it is a good time to be in the desert southwest, typing this blog on a sunny front porch under blue desert skies.
