  Ku has been in radar mode for two hours now.
  

  
  With switching to manual phase (last 100 feets) do we get some views from cameras?

  10 second MC4 burn in 1:20
  

  
  I think he said 2.2fps via RCS jets.
  

  
  Both correct. A 2.2 fps burn requires 10 seconds to trim using RCS.

  Yes, the crew will configure Ku for COMM at 100 ft. TV coverage depends on TDRSS.

• Crew can command the telescope, just cannot see telemetry on orbit

• within 400ft.

• Sounds like they are little behind on the HST commanding, so they are going to drop the commanding to roll the telescope (42 degrees) and Scott Altman will change the orbiter yaw to account for that...the commanding would have required approx. 16 minutes...
  
  STOCC waiting for TDRS link...
  
  Crew just called 300 ft (range)

• Crew stationkeeping where they are...range of 250 feet...STOCC now commanding HST through TDRSS...orbiter PI has lock...
  
  Waiting to complete commanding sequences...

• Interestin.. while watchin this approachin phase I saw yellow and white curves which show thrust from RCS, but is there some diffrence between these two coulours/meanings of?
  
  I attached little example :

  Edit: sorry misunderstood.
  
  The yellow are vernier thrusters, white are regular.

  Take the yellow range/rdot with a grain of salt. The onboard nav state is walking off from the radar. They're really about 250 ft right now. Crew is flying with raw radar and HHL.
