ISS will make a 6-minute passage over Charlestown in mostly clear skies
By Will Collette
If you missed the overflight of the International Space Station (ISS) on Saturday, you have another chance tonight, as the ISS makes a good, long six minute pass tonight.
The forecast is for a mostly clear sky at a cool 55 degrees temperature when the ISS makes its run starting at 7:31 PM in the west-southwest. It will appear at an elevation 10 degrees over the horizon and will make a virtually flat passage to a maximum height of 44 degrees.
It will run for six minutes total until it seems to disappear at 10 degree over the northeastern horizon at 7:37 PM.
Overflights are serene - totally silent and beautiful, unlike any other object in the sky, except for some of the other satellites.
You can sign up with NASA to receive same day notices of overflights, or consult the overflight log. The overflight log says the ISS will make a SECOND pass over Charlestown tonight at 9:09 PM but that one will only two minutes and will be very low (maximum height 16 degrees).
This is the message I received from NASA: Time: Mon Sep 20 7:31 PM, Visible: 6 min, Max Height: 44°, Appears: 10° above WSW, Disappears: 10° above NE
