So far, it’s been binoculars if you wanted to see the comet PANSTARRS, but that might change tonight.

At 8 p.m. the comet will be one-third the height of the crescent moon and a little bit to its right — and it ought to be visible, Terry Richardson, College of Charleston astronomy professor. Friday night PANSTARRS will be a little bit higher than that, but still to the moon’s right, he said.

Its tail is about an inch long to the eye.

The twilight so far has obscured the comet unless viewers used binoculars, he said. But it should be visible to the eye into next week, until the waxing moon becomes too bright.

“An absolutely unobstructed skyline will be necessary” to see it, he said.
