Having dug out my old tracking program in the last few days I was going to list the times when you might be able to see the shuttle pass across the skies ,but tonight and tomorrow night are the last time you'll have a chance while the Shuttle is docked with ISS.
There is a low angle pass tomorrow night between 2121.30 BST and 2130 BST with the highest point in the sky at 2125.30 BST with an Elevation of 10 degrees.
Now the further North you are from Northamptonshire the earlier the pass will start and the max elevation could well be different. Also if your to the South times will be slightly later.
Once undocked and in a stable orbit there is a chance of further observations of the Shuttle but ISS is in a phase where all the passes are during daylight hours.
You also might have the APRS Digipeater active on-board ISS and possibility of voice coms if they have time. If I remember correctly you listen around 145.840MHz on FM.
But for other Shuttle coms I have the radio in the car monitoring 259.700 MHz AM. During Launch and Re-Entery Satcoms on 261.875 FM can be heard.
ISS = International Space Station.
Later on in the mission when undocked if the predictions look good to be able to see it with the naked eye I'll post the details.
