Loss of video.  Webcast host says Falcon 9 and SES are now in orbit.  No additional word on if we have had SECO.  Saying to check their website for further updates.


EDIT:  SECO has occurred, but still have another critical engine restart coming up for the second burn.

The "AOS Bermuda" call talked over (and drowned out) the launch/flight controller; I thought I heard a SECO call under the AOS Bermuda call, but wasn't sure.

If you rewind back to the stage separation, you can clearly see the first stage performing some RCS burns. Probably the best images of first stage RCS so far.
For a variable Isp spacecraft running at constant power and constant acceleration, the mass ratio is linear in delta-v.   Δv = ve0(MR-1). Or equivalently: Δv = vef PMF. Also, this is energy-optimal for a fixed delta-v and mass ratio.
