Tonight (technically, tomorrow morning) from 1:16am to 7:16am Pacific Time will be a six-hour launch window for an ICBM test rocket.
Our sun is set to rise on Saturday at 6:03am, so depending on when the actual launch time is, this will give us the potential of seeing the “SpaceX Glow” which everyone was so excited about last year!
Depending on your location and the ambient noise around you, you may hear a distant, muffled rumble or perhaps a sonic boom from the launch some time between 4 and 12 minutes after launchtime.
If you want a close-up view of the launch, you are welcome to congregate west of Lompoc in the vicinity of highway 246 (west Ocean Avenue) and Union Sugar Road.
If you plan to obtain countdown status via an Internet feed, be advised that the feed may lag far behind the actual countdown. During a launch last year, Pete Heins, N6ZE, discovered the countdown feed was delayed by a whopping 75 seconds, so being attentive to the sky is a must, if you plan to watch it outdoors.
