T+2 minutes. We have BECO and booster separation. Too bad the Korolev Cross can't be seen in the night sky.

Second stage continues to burn well.

T+3 minutes. Coming up on fairing separation in about 30 seconds.

Altitude 80 kilometers, speed 2.05 kilometers a second, downrange 145 kilometers.

T+3 minute, 33 seconds. Fairing separation confirmed.

We'll expect second stage Main Engine Cut Off (MECO) to occur at 4 minutes, 47 seconds. Using a hot-fire method, the third stage will ignite at the same time MECO occurs, severing the interstage lattice structures and separating the second stage. A few seconds after staging, the three interstage pieces will fall away from the third stage engine.

T+4 minutes, 30 seconds. Second stage propulsion is healthy; standing by for MECO and staging.

T+4 minutes, 50 seconds. Second stage MECO, third stage ignition, second stage separation, interstage jettison. All four events looked good.

The single RD-0124 engine will fire until 9 minutes, 22 seconds. After SECO occurs at that time, there will be a 1-second coast phase before Fregat separates.

Getting good data from the Galliot tracking station. Nothing's ratty thus far.

We have SECO. Third stage has shut down and separated.

And the tumble valve has opened on the third stage's fuel tank.

Exactly 60 seconds will pass between Fregat separation and Fregat MES-1. After the latter occurs, the single firing of the Fregat's S5.92 engine will last 17 minutes and 37 seconds.
