For all of you in Southern California.

MONDAY VANDENBERG LAUNCH

An Atlas V booster carrying a classified National Reconnaissance
Office payload is scheduled for launch from Vandenberg AFB Monday
evening. The Atlas is set to lift-off from south base at 20:29 PDT.

Following lift-off, the Atlas will probably will head southward.
Several minutes later, the vehicle will place the NROL-41 payload into
orbit.

Weather permitting, tomorrow's launch should be visible to the unaided
eye for more than 150 miles.

Because of the launch time 8:29 pm it should be very visible to most in the southern California area. It will rise above the horizon into a dark sky and the sun should illuminate the contrail and make it very bright.
