VIDEO: Near perfect conditions for Space Station Charlestown 6 minute overflight

"Clear" forecast for ISS at 7:28 PM 
By Will Collette

The National Weather Service says that today's sunny weather will lead to a clear but cold night tonight. 
That's good news for watching the International Space Station (ISS) float over Charlestown for six minutes at 7:28 PM.

A six-minute overflight is the maximum for these overflights, arcing over almost the entire sky. I'm hoping we catch a break on the clouds.

I love these overflights and the soothing feeling they produce in the midst of all our troubles, not the least of which is the impeding battle to fill the Supreme Court seat of the amazing Justice Ruth Bader Ginsburg.

At precisely 7:28 PM, the ISS will suddenly appear in the southwest 10 degrees above the horizon as the light from the sun, set beyond the horizon, catches it.

It will arc overhead to a peak of 71 degrees and then disappear in the east northeast six minutes later as it losses the reflected glow of the sun.

National Weather Service prediction is here. 

Here's the message I received from NASA this morning, courtesy of their "Spot The Station" e-mail listserve:

Time: Sat Sep 19 7:28 PM, Visible: 6 min, Max Height: 71°, Appears: 10° above SW, Disappears: 11° above ENE  

Celestial mechanics makes the ISS strictly follow these specifications.
