Excellent - looks like a good first apogee repointing maneuver! -2.5
degrees off the sun at apogee.

Guys,

   The apogee post burn contact was nominal for command/telemetry

The station power was increased from 277 watts to 370 watts to avoid
telemetry drop outs during the contact

@1628 ebno=19.67 - 20.94 db (2ksps)

agc signal strength= -121.584

@1649 ebno=19.73 - 20.72 db (2ksps)

agc signal strength= -119.902 with power increase

 

VC0=104/22
