How to Watch the Launch of LADEE (with lots of images), Orbital
" ... Although the views are shown in daylight, the LADEE launch is scheduled to occur at approximately 11:27 PM EST. The views below give an indication of the direction where you should look to see the launch, along with nearby features. In addition, weather and local lighting conditions can and will have a large effect on what a viewer will see."
Keith's note: Luckily for me, I can walk across the street from my house in Reston, VA and look at an opening in the trees to the east and see nearly all of the launch.
