Wikipedia (actually Wikimedia) has an image of Falcon 9's 2015 launch during its night flight (16th flight in total) that took place on Sunday, March 1, 2015 at 10:50pm ET:
I was wondering what is pictured in the background near the right bottom corner?
There's a lot of light pictured in that place. Is this a "normal operational" of the flight's control area (i.e. happens during any flight) or does that much of light suggest some other rocket's engines burning / another rocket's preparation for the next flight?
