I did not see the LADEE launch from NASA Wallops earlier in the month. But a ton of people did. Tomorrow (Wednesday September 18th), Oribital Sciences and NASA Wallops will launch the Antares/Cygnus mission to resupply the International Space Station. Viewing possibilities from the Mid-Atlantic region can be found here. I made another view from Rt141 and Rt48 west of Wilmington Delaware to show where to look but I used the Google earth data from the April launch information since there didn't seem to be a file from tomorrow's launch.
You can see the Delaware Memorial bridge just under the red part of the trajectory left of center in the picture. That's a pretty visible point to look for while looking south east.
The window is from 10:50 am to 11:05 am. Maybe we can see this one.
