All quiet out there at the moment, with all 22 drivers waiting in the garage.
Reports of tumbleweed rolling down the star/finish straight are unconfirmed.
Ricciardo heads out again, doing a practice start at the end of the pit lane and heading out.
@PeterM: Hi Peter. We are currently working to rectify this issue.
Merhi heads back out in the Caterham, meaning he and Bottas are currently on the circuit.
@Prasad: With all the Alonso rumours this season, I don't think it's THAT unlikely ;)
And Verstappen is back out on track as cars start filtering out.
@Chuck: Racing on Monday is almost certainly out of the question due to the travel involved with getting to Sochi. A race on Saturday or even earlier on Sunday would have to be the compromise.
Bottas sets the first meaninful benchmark of the session, a 1:37.436.
We have a Caterham off just after the Spoon curve, compromising a lap Verstappen was doing. Looks like it was Merhi, who is currently second with the only other timed lap.
Looks like he just got wide coming through that hairpin and then lost it coming back on the track and Bottas had to slam the brakes on to avoid the Mercedes junior.
Verstappen's first lap in an F1 car is seven seconds off the lead but he did have to slow significantly for that incident.
Alonso slots in behind Bottas before Hamilton jumps up into P1, setting a 1:26.745.
@Damo: Ah, I wasn't talking about the crowd, more the fact nobody was on track at that moment!
Rosberg shaves three tenths off Hamilton's benchmark to go P1. The new benchmark a 1:36.437.
And Hamilton loses a chunk of time in the middle sector and can only move to within a tenth of Rosberg with his latest run.
@PeterM: Nice change for this season, isn't it.....
Raikkonen's first lap puts him P6, slotting in behind Button but still a full second off Alonso - but the Spaniard has done a lap more.
@Chuck: As I said, the FIA will monitor the weather today.
Rosberg lowers his benchmark even further, going purple in the final two sectors. The top time now a 1:36.550.
Vettel's first lap is good enough for only P10, four tenths down on Ricciardo.
Worth noting teams may start limiting mileage this weekend to save crucial engine components for the end of the season with the prospect of penalties looming.
Gutierrez has a little off but manages to recover the car.
Gutierrez has another lock-up as Button drops his McLaren onto the grass but continues.
Pardon me, Hamilton drops his Mercedes onto the grass but continues. Looks like he had a bit of understeer.
Kvyat currently P5, with Verstappen down in P12. Possible Verstappen had some issues after that earlier radio message.
Looks like Vettel had a big, big lock-up as he entered the pits and realised how fast he was going approaching the white line.
