Someone got the serial numbers of rocket parts for this flight?  ;)

End of ILS broadcast.

Congratulations to ILS and Gazprom for a successful orbital insertion!

No worries Chris. Glad to be of help.

Yamal-401 | Second Burn
December 14, 2014 8:50 pm (GMT)
ILS Communications Team

As the Breeze M upper stage of our Proton M rocket continues its climb into space with the Yamal-401 satellite onboard, we have received confirmation that the 2nd burn of the upper stage occurred and shut down as scheduled.

The next events are scheduled for about 2 hours from now. The Breeze M upper stage will ignite for a 3rd time and burn for approximately 18 minutes; after that the additional propellant tank will be jettisoned. All this will happen in a span of almost 20 minutes while the vehicle is again out of range of a ground station. We should reacquire the vehicle shortly after the APT is jettisoned.

Wow, I think this the first time I've seen 2nd stage sep./3rd stage ignition from Baikonur! (easy to see down-range, but not from the launch site)

Briz-M's 3rd burn should be completed by now and external fuel tank jettison should happen very soon. We will know very shortly when it comes back into ground station coverage.  ;)

Briz-M's 3rd burn and APT jettison completed without issues. 4th and last burn starts at 09:03 UTC.

Ground control confirmed that the third engine firing and the separation of the external tank had actually took place.

04:15 UTC
The telemetry accumulated onboard Briz-M during the flight out of range of ground stations and later downlinked to mission control indicates that the third engine cutoff and the jettisoning of the external tank took place 11 seconds ahead of schedule. (It is not an indication of a serious problem).

All first three Briz-M firings were a little shorter than planned:
1st burn: -5s
2nd burn: -14s
3rd burn: -11s
APT was jettisonned 11s early
(should not represent an issue at this stage)

What seems to be the Briz-M auxiliary tank (APT) has been catalogued by USSTRATCOM:
2014-082A/40345 in
397 x 35622 x 47.63° Arg of perigee: 359.88°
Planned orbit for APT was:
383 x 35651 km x 47.6° Arg of perigee: 0°
