That will be the second maximum length flight in a row. There is a 30% chance of rain and showers -VERY much needed today and tonight. If we don't get the rain, we may get another long view of the ISS.
To be more precise, the ISS will suddenly appear at 9:07 PM in the sky at 10 degrees above the horizon in the west southwest. It will rise to 65 degrees at maximum height, about two-thirds up the sky from the horizon.
It will end its journey by disappearing at 9:14 at 10 degrees above the horizon in the east northeast. I always find it to be beautifully serene as it makes its silent pass.
Given the astrophysics, seven minutes is pretty much the longest possible time for a pass over Charlestown.
The weather today has been clear, but the National Weather Service forecast for tonight says "increasing clouds." That's the main variable affecting your view tonight.
Here are the overflight details from NASA:
Time: Thu Jul 14 9:07 PM, Visible: 7 min, Max Height: 65°,
Appears: 10° above SW, Disappears: 10° above ENE
