There's a practice standing start, but only two drivers taking part.
Gabriel Bortoleto and Isack Hadjar - the 2024 F2 winner and runner up.
There's five minutes to go. Time for some race practice, first up is a virtual safety car.
Next, a practice red flag.

Another unusual occurrence: glass on track.
Red Bull were about to send Max Verstappen out but had already delayed when a number of team members ran to the pit wall to look up and down the straight, because warning flags were being displayed.
A pane of glass was the culprit, that had fallen from the starter’s box above the track. A brief red flag saw it quickly cleared up, although it was maybe slightly too quick as Fernando Alonso headed out and then the red flag returned immediately, so he had to come back into the pits again.
Andrea Kimi Antonelli was behind Charles Leclerc, out on the track. He overtakes the Monegasque and gets on with his lap.
Lando Norris, Jack Doohan, Max Verstappen and Olvier Bearman are all in the garages.
The other drivers are out on track, getting in the laps with 10 minutes to go.
Max Verstappen (Red Bull) - 47
Alex Albon (Williams) - 54
Lando Norris (McLaren) - 57
Charles Leclerc (Ferrari) - 60
Andrea Kimi Antonelli (Mercedes) - 55
Fernando Alonso (Aston Martin) - 43
Jack Doohan (Alpine) - 61
Oliver Bearman (Haas) - 59
Isack Hadjar (Racing Bulls) - 67
Gabriel Bortoleto (Sauber) - 30
Max Verstappen has hopped out of his Red Bull and taken off his helmet.
He's having a chat with his team. Will he be out again before the morning session is over?
Jack Doohan and Charles Leclerc have also completed a race length.
Leclerc is on 58 laps and Doohan has completed 60.

Image source, BBC SportThe final day of testing tends to be when upgrades are introduced, and teams run something closer to their Melbourne race packages.
Doing so allows them to understand the impact an update will have on the car, which can then prove whether they have the right development plans in place for the year ahead or need to address anything. It also has the added bonus of hiding any innovative solutions from competitors until as late as possible.
As one example, there’s a new nose on the Red Bull today, which is connected to the second element on the front wing (see the small gap below the tip of the nose), rather than the very lowest element as was the case with the launch specification.
Lando Norris is back in the McLaren garage and hops out of his car.
He has completed 57 laps, a race length at the Bahrain Grand Prix.
Under 30 minutes to go.
Everyone is out on the race track apart from Isack Hadjar.
Max Verstappen makes his way past Oliver Bearman.
It's like a race start with most cars heading back onto the track.
Lando Norris has just set an overall fast time on sector one.
The debris has been cleaned up and session has now resumed.

Apparently it’s a pane of glass from the starters box, so that will need clearing up quickly.

Drivers are back in their garages, while the glass is being swept up. While we wait to get going again, let's have a look at the lap times.
It looks like a window has shattered in the box where the chequered flag is waved.
I think we've seen it all in this pre-season testing.
There's a red flag being waved, there's debris that has fallen from the start finish box.
Andrea Kimi Antonelli is racing down the track, he is in a spot of traffic but overtakes Alex Albon.
A little bit of practice for the rookie ahead of his first F1 season.
