We've seen every car apart from the Lotus (and Force India who aren't here, obviously) this morning, but the track has now fallen silent.

Approximately 0.2 mm of rain fell in the 20 minutes leading up to the start of testing this morning, so rain tyres have been the order of the day so far.

"Leaving aside McLaren's problems, Sebastian Vettel and Ferrari have grabbed the headlines so far in testing, with the fastest time on both the first two days. Vettel, who hands over to new father Kimi Raikkonen today, was given a round of applause by the Ferrari pit crew after returning to the pits at the end of the day, and joked that they were just pleased he hadn't damaged the car in the damp conditions.

"Vettel says he has been encouraged by progress so far. 'It is still very early to tell because it depends on how you compare to other people,' the four-time world champion said. 'Mercedes are doing extreme long runs, and in that regard it is difficult. I am quite happy with the feeling inside the car and I think we have a good platform to work from.'"

Nico Rosberg is out early setting the pace, the Mercedes driver leading the way with a 1:33.058, 1.7 seconds clear of Daniel Ricciardo's Red Bull.

It's been a pretty busy opening half an hour already, with Carlos Sainz Jr, Felipe Nasr, Fernando Alonso and Felipe Massa also posting times.

McLaren's Fernando Alonso completes two successive laps to put a time on the board - a 1:42.304 which is seven seconds off the pace. Still, it's a lap.

The conditions are far from ideal in Jerez, with the track damp and greasy. But that's nothing compared to what it's like over at the legendary Brands Hatch in snow-hit Kent.

Nico Rosberg is the first man out on track, with Kimi Raikkonen, Daniel Ricciardo and Fernando Alonso joining him. Yes, you read that right, Alonso in the McLaren is out on track. How long that lasts is anyone's guess.

Nico Rosberg is back behind the wheel of the Mercedes today, with Daniel Ricciardo making a return for Red Bull.

Felipe Massa gets his first taste of the new Williams, while Fernando Alonso is back in at McLaren.

Kimi Raikkonen takes over from Sebastian Vettel at Ferrari, Carlos Sainz Jr is testing the Toro Rosso, Romain Grosjean gets a go in the Lotus and Felipe Nasr is in action for Sauber.

Only Force India are not at this test, after deciding to concentrate on the final two Barcelona tests.

"It's all eyes on McLaren on Tuesday morning. After two days in which Fernando Alonso and Jenson Button have managed just 12 laps between them because of a recurring control-systems issue on the Honda engine, it is time the team got some serious work done. Button and McLaren both said on Monday evening that they felt they had found the problem, and they are about to find out whether they are right.

"Despite the trying start to the programme - remember this comes after they completed just five laps in two days with a 2014 test car fitted with the Honda in Abu Dhabi last November - so far, they have stayed resolutely positive.

"'We've had a few little niggly problems, control issues but we feel the last run was good and we've solved them so hopefully the last two days will be much better,' Button said. 'The packaging and how tight the bodywork is and temperatures; all that stuff is working really well.

"'But if you've only done six laps that's what people see. I'm sure we'll have more problems over the next couple of days - these engines are so complicated - I just hope we can do a bit of running and get a bit of data back to the factory and see where we are and where we need to improve.' Alonso is back in the car on Tuesday."

There's no point reading into headline times because we don't know the spec in which each team is running their car, nor do we know fuel loads.

But Ferrari and Sebastian Vettel will still be pleased with their efforts so far as the German finished top of the pile on both days and racked up a solid amount of laps.

It's been pretty positive for Mercedes, too, aside from a water leak which curtailed Lewis Hamilton's running yesterday. Still, the team have completed nearly 250 laps - significantly more than anyone else - in two days.

It hasn't gone so well for McLaren, though.

It is considerably warmer this morning than on the first two days of the test, with the air temperature hovering around 10.4C and the track temperature 9.4C.

Today's session has just got under way and will run until 16:00 GMT. That's eight hours for the teams to continue putting their 2015 challengers through their paces and iron out any issues as the new season approaches.
