CAPE CANAVERAL, Fla. (AP) A newly discovered comet is swinging through our cosmic neighborhood for the first time in more than 400 years.
Stargazers across the Northern Hemisphere should catch a glimpse as soon as possible either this week or early next because it will be another 400 years before the wandering ice ball returns.
The comet, which is kilometer-sized (1/2-mile), will sweep safely past Earth on Sept. 12, passing within 78 million miles (125 million kilometers).
Early risers should look toward the northeastern horizon about 1 1/2 hours before dawn to be specific, less than 10 or so degrees above the horizon near the constellation Leo. The comet will brighten as it gets closer to the sun, but will drop lower in the sky, making it tricky to spot.

Now is the time to pull out your binoculars, telescope, or camera. This brief but bright comet is only visible for another week.

Not like I'm not up then anyway. Out watering plants in the Sonoran Desert East that we euphemistically call "East Texas."

Normally, I let the folks with big telescopes do the dirty work for me, but "just this once" I wanted my own photo.
Back to letting NASA take the pix!
