What a morning of sky sights, both before dawn and after sunrise.
December 7 – This was the prime day I came to Arizona to enjoy, to be better assured of clear skies. As it turned out this will likely be the cloudiest day of the week here, but skies were clear enough for a fine view of a conjunction and an occultation. The comet was a bonus.
At 4 a.m. the waning crescent Moon rose accompanied by Venus, as the two worlds appeared in close conjunction in the pre-dawn sky. The view above captures the scene as the Moon and Venus rose over the Peloncillo Mountains of New Mexico. Comet Catalina is in this scene but barely visible.
An hour or so later, with the Moon and Venus higher and with skies a little less cloudy, I was able to capture this scene, above, that included Comet Catalina, as a tiny blue dot next to Venus and the Moon. But if I hadn’t labeled it, you wouldn’t know it was there! The comet is proving to be less wonderful than anticipated, and any cloud dims the view even more.
I had hoped for a superb scene of a bright comet next to the two brightest objects in the night sky. But comets do what comets do — surprise people with unexpected brightness (as Comet Lovejoy did last January) or with disappointing dimness … or by disappearing altogether, as Comet ISON did two years ago. I came here in December 2013, to this same location on the Arizona-New Mexico border, to catch ISON but no luck there at all!
Regardless of the comet, the conjunction of the Moon and Venus was stunning, about as good as such events get. Here’s the view, above, an hour later again, with the eastern sky brightening in the dawn twilight. The only thing that would have made this event even more spectacular is if the Moon had actually covered up Venus in this twilight sky. Not quite.
For the occultation itself, we had to wait until well after sunrise for an event in the blue daytime sky, at 9:30 a.m. local time.
All of North America got to see this fairly rare occultation of Venus by the Moon, albeit in the daytime. Nevertheless, the two objects are so bright, this was visible to the unaided eye, even with some cloud about. In binoculars it was wonderful.
To shoot it, all I had was a telephoto lens, so the image scale doesn’t do the event justice. But the image above provides a good impression of the binocular view, with Venus as a brilliant jewel on the “ring” of the Moon.

Alan, not sure why but both the email and your website no longer have a link to the high resolution version of the images. Have you stopped providing this?

I’m aware of that and it’s the fault of WordPress who keep changing the interface for publishing blogs. Now embedded images aren’t downloadable, unless I use the old publishing interface it seems. They keep trying improve things only to screw things up.
