NROL-71 Set to Launch
Rick Tejera notified this list about tonight's rocket launch from Vandenberg.
Here's a good site with a countdown timer and live webcast.

Launch is scheduled for 6:57 MST, which is favorable for great backlighting of
the plume. Everything is currently a go, but gusty weather means that there's
only a 20 percent chance for favorable launch conditions.
