Just fifteen minutes until the second practice session gets under way in Valencia. What a treat on a Friday afternoon

Narain Karthikeyan getting in the way of Fernando Alonso as the Hispania man headed into the pit lane, much to the frustration of the Spaniard

Turn 12 also where people are struggling Narain Karthikeyan rolls off there, a quick turnaround and he's off again though

Jenson Button declares he's really struggling with rear grip at high speed, which would explain why he's languishing in 11th spot

Seems like turn ten is causing a few problems for a number of the drivers, Massa suffering some serious rear locking going into that corner. The wind direction there not helping matters.

Both Ferrari men are giving it a go on hard tyres and it's not making much difference for them, Massa just going round in a very similar time to before and remains fourth

Kamui Kobayashi continually locking up in the Sauber and producing huge amounts of smoke, the dust isn't helping the situation

Vitantonio Liuzzi in his Hispania wides far too wide on the tenth and narrowly avoids the wall

Maldonado showing that the soft tyres are going well as he improves his time and position to fourth

Heidfeld running on the medium compound is working well as he bumps Massa out of the top five

Reports suggest Paul di Resta is getting increasingly frustrated waiting for the damage to his car by someone else to be fixed

Sergio Perez is fully recovered from his dizziness now as he comes out in his Sauber and goes straight up to tenth place

Michael Schumacher preparing to head out and hopefully improve on his 11th place this morning

Pastor Maldonado tries out the soft tyres and moves straight into fifth place, good move from Williams it seems

Still waiting to see the Force India car, at the hands of Hulkenburg or Paul di Resta, still plenty of time yet though

Alonso briefly ruins the symmetry of the top four, but the Australian Webber reclaims his second spot and is now just 0.002 seconds behind Vettel

Jaime Alguersuari says that he won't be racing this afternoon in his Torro Rosso due to some unspecified technical problems

So it's both Red Bull's follwed by both Ferrari's at the top Hamilton is next and McLaren will hope he can be joined by Jenson Button who is back in 8th

Webber joins his team mate at the top of the leaderboard, but remains half a second behind him

Looks like the world champion was just teasing everyone this morning as he takes his time right down to 1:39.79

The Renault drivers had a very positivestart to the day but are getting pushed out a little this afternoon with Petrov and Heidfeld down in 6th and 7th respectively

There goes Vettel to the top of this session and the quickest of the day, any of those suspicions about him having an issue this morning have been dispersed
