These clear nights may be frosty and a good reason to stay inside, but Mel Knutson also sees beauty in them and a reason to step out.

NASA's International Space Station is slated to fly over the North Idaho sky tonight from 6:12 to 6:18.

On Sunday night, it will fly over from 6:38 to 6:43 and Monday from 7:05 to 7:08 p.m.

"If it's clear, the station should be really visible," said Post Falls' Mel Knutson, who has followed the ISS flights for several years as a hobby. "It should be about as bright as the moon. If you watch closely, you should be able to see the space shuttle trail behind it.

"This is one of the best places in the United States to watch it."

With 10-power binoculars, Knutson said he's able to make out details of the space station.

"What looks like black wings are the solar panels," he said.

Knutson said those with strong camera lenses can get good shots, but it's too hard to follow with a telescope.

"It's traveling at about 1,900 mph," he said.

The ISS doesn't follow the same orbit every night.
