Awaiting word over the LD net on Upper Level Winds and Ground Winds.  Per the last published forecast, today's prime concern was ground winds.

Publicly available ground wind data shows very lite winds.  Upper Levels Winds look, themselves, within tolerance... but some directional shift as you ascend.  Wind sheer might be an issue.  Awaiting official word.

Propellant loading poll complete.  All technical and weather constraints are GREEN.

Range is tracking one range violator, but they are proceeding with prop load.

T-1hr.  No issues.  Fueling proceeding well.  Only item being tracked is a vessel in the Range restricted air/sea space.  That is not expected, at this time, to interfere with launch.

Range just updated the team on a tracking station that is not supporting this launch.  This was known in advance and is not an issue as the vehicle is "redundantly tracked during this period."

T-45mins and counting.  10 mins away from the start of LOX load.  All is proceeding well.  No issues that would prevent launch at 06:17 PST (14:17 UTC)

Stage 1 RP-1 fueling stopped at topping target (normal).

All teams asked now to report anything that would constrain the start of LOX load.

All is quite on the LD loop.  No issues with LOX load or the auto-sequence.
