So the first half hour is up and that means the teams will hand back their spare set of prime tyres givben to them by PIrelli.
And with the end of that half hour, everyone returns to the garage.
Chilton and Magnussen the only men without a timed lap yet.
It appears that timing issue is resolved on our live comms. Please do let me know if you are still unable to see the list of drivers and lap times.
That Toro Rosso nose the most significant change today. Verstappen running the usual 2014 nose on the other Toro Rosso.
There's an image of Verstappen by way of comparison.
Great shot off two men eating noodles in the grandstand. That's the most exciting thing currently happening at Suzuka. Second to this live commentary, obviously.
Fernando Alonso is eating grapes in the Ferrari garage.
The Mercedes drivers look like they are gearing up for another job.
Vettel is the first man to break the silence out there.
Caterham's Merhi is on track too.
Marussia confirms Chilton is preparing for a run, so he should set a time shortly.
Vettel, with that pewter helmet design, improves to P8 on his latest run.
That latest time for the world champion is 1:38.020.
Raikkonen is also out on track for Ferrari.
Toro Rosso has managed to make its new nose look even stranger.
The most striking thing for me in this session so far is Bottas' time. Traditionally this year Williams has done very little on Fridays and then come to life later in the weekend. Rob Smedley said he was optimistic about this weekend's race, remember. Keep your eyes on those Martini'd cars this weekend, I'd say.
Rosberg and Hamilton are now out on track, along with Magnussen and Maldonado.
Still no sign of another run for young Verstappen.
@Robert: Not yet, it is set to happen some point this weekend however. Will no doubt have a news story on ESPNF1 when they do.
Ricciardo the latest driver to run wide onto the artificial grass in the second part of Denger. Surprised that's not all been tarmac'd, to be honest...
Ricciardo improves to P6, as Rosberg lowers his P1 time to a 1:35.461.
Hamilton moves back to 0.151s of Rosberg.
Looks like Hamilton ran wide at Degner again, however.
@Chuck: I don't believe there is - happy for an American commentator to correct me on that.
@mfbull: I think the idea of sandbagging is over-egged slightly by fans. There's not a huge amount that can be gained from holding back in these crucial sessions, in my view. Especially not from your team-mate, as you're both striving to optimise the set-up of the same car.
Alonso jumps into third, half a second down on Rosberg.
