Hi, Here are the viewing circumstances for SPOC and SLC for this coming Saturday morning's burn of the CONTOUR spacecraft's propulsion system. The satellite itself will be in darkness and therefore invisible. However, the burn could be visible with telescopes and maybe even binoculars.

Note that the above could change between now and Saturday. If it does, I'll post updates as needed. Let's hope for good weather Saturday morning. Cheers! Patrick :-)
