Second practice is under way!
First practice pacesetter Kimi Raikkonen is out on the track, as is Romain Grosjean.
Amit Mandalia: With Kimi now signed up who is the next key driver for the 2018 driver market? Also, Leclerc at Sauber next year?
Fernando Alonso to Williams? That's one of the rumours kicking about at the moment. The driver market starts to hot up over the next few weeks, who do you want to go where?

Sebastian Vettel legs it down the paddock, slapping Christian Horner's back as he does so. The two have a quick catch up before Vettel continues on his way to the Ferrari garage.
Two minutes to go until second practice gets under way.

Renault say there are “still question marks” over whether Robert Kubica can make a full-time return to Formula 1 after life-changing injuries.
The 32-year-old Pole has had three tests with Renault in the last three months, six years after he suffered a partially severed right arm in a rally accident.
Renault F1 boss Cyril Abiteboul told BBC Sport: “Have we definitively answered the question whether he can race again? No."
Kubica’s manager said he believed he had “shown he can be a serious candidate”.

Second practice gets under way at 13:00 BST and you can listen to audio commentary online from just before then. Tune in.
Kimi Raikkonen certainly knows how to win in Belgium. A fifth of his career victories have come at Spa with the Finn winning in 2004, 2005, 2007 and 2009.
It was a relatively low-key showing by Max Verstappen in first practice as he finished fourth quickest.
Instead the session belonged to Kimi Raikkonen. The Finn celebrating his new Ferrari deal by topping the timesheet ahead of Lewis Hamilton.
The session, though, did not really tell us a lot about who is looking strongest for the weekend. That may well become a little clearer in second practice.
Yes Belgium will be looking distinctly orange this weekend as thousands upon thousands of Max Verstappen fans cross the border from the Netherlands to see their hero in action.
The Belgium-born Dutchman will certainly be hoping their support can propel him to only a second appearance on the podium of the season.
Imagine 80,000 people.
That's the Santiago Bernabeu sold out...
Or the entire population of Burnley...
A lot of people isn't it?
That's how many Dutch fans are heading to Belgium to cheer on Max Verstappen...
It's a Ferrari at the top of the timesheet but we never saw Lewis Hamilton's true pace. When we do, I get the feeling Mercedes are going to be in a league of their own.
Second practice should paint a clearer picture for us, join us for build up at 12:30 BST.
In the meantime, have a read of Andrew Benson's take on first practice.

Kimi Raikkonen finishes fastest in first practice for the Belgian Grand Prix.
Rachel T: Lewis looking mighty on the 'slower' tyre - but is this all academic if it rains on Sunday?
And Kimi Raikkonen goes fastest of all with a 1:45.502.
It's 0.053s quicker than Lewis Hamilton's time, but is set on the ultra-softs. With Hamilton doing his time on softs, the Mercedes is looking the team to beat so far...
"It seems that it works now," says Fernando Alonso, presumably referring to DRS.
Meanwhile, there's a flying Finn on the track. Kimi Raikkonen is on a quick one.
