Just an installation lap for Lewis Hamilton as Daniel Ricciardo - fastest this morning - takes the Red Bull back out onto the circuit.

Lewis Hamilton is on track for the first time in 2018 testing after taking over from Valtteri Bottas, who finished the morning with the second quickest time - 1:20.349.

Fernando Alonso immediately improves on the time he managed this morning, going a whole second quicker with 1:23.112. He remains eighth, however.

And here comes Fernando Alonso with all four wheels on his car.

Once again he is back out on the super-softs.

Mercedes: Hamilton

Ferrari: Raikkonen

Red Bull: Ricciardo

Force India: Mazepin

Williams: Sirotkin

Renault: Sainz

Toro Rosso: Hartley

Haas: Grosjean

McLaren: Alonso

Sauber: Ericsson

Lex: Someone is going out on track??? It's a February miracle!

A little bit of rain ain't stopping Sergey Sirotkin. Off he goes in the Williams and with it the fear of an afternoon of tedium eases.

WE HAVE A CAR GOING OUT!

There was an interesting suggestion from former F1 chief executive Bernie Ecclestone recently as he said he believes the sport needs to embrace an all-electric-powered future.

“Can’t we do this?” he said in the Guardian., external “The manufacturers provide the cars themselves but we aren’t going to pay them because they get massive worldwide publicity. It would be a super Formula E, if you like.

"You can make cars be like an F1 car and the only thing you would miss would be the noise and I do not believe that people could not come up with something to make more or less the old F1 noise."

Thoughts?

Lex: Great track action going down, 10/10 recommend.

While we are waiting, we've got a vote going asking which team has the best-looking car.

Head here to cast your vote.

We've got 25 minutes on the clock and there's still no sign of any movement.

I'm in real danger of having to space fill soon. That will not be pretty.

While we wait for something - anything - to happen, check out the video below as Jolyon Palmer gives his view on the halo.

Palmer, who competed for Renault in F1 across 2016 and 2017, will this season join the BBC Formula 1 team to give in-depth views and analysis of the sport.

Joanna Harran: Hello Gary, long time no.. read. Although not fussed for orange I think the McLaren looks great. Now if they can only keep the tyres on.

Welcome along, Joanna! For the tyres to be kept on while the cars are in motion they actually have to go on the track. We're still waiting...

There is also a bit snow forecast in Barcelona on Wednesday.

Meanwhile, the Honda-powered Toro Rosso managed an impressive 72 laps this morning.

Last year, McLaren managed just 29 laps all day with the Honda engine on the first day of the first test.

Ten minutes into the afternoon session and still no-one fancies it.

Nico Hulkenberg is the man sat at the top of the lap count table at the moment on 73, with Fernando Alonso propping it up on 10.

Alan Cummings: If McLaren do another 40 laps will just about save face.

Jennifer Harris: Having watched Alonso's off on Twitter it's hard to see the cause. Did the spin cause the wheel nut to break or did the wheel nut break and cause the spin?

The clouds have gathered as the afternoon session gets under way.

No-one is heading out. Stubbornly refusing after losing 10 minutes of the lunch break?

No-one likes work ticking into your lunch break to be fair.
