Barcelona February Test Test day two

19:10 That's it for today. Tomorrow's commentary from Barcelona will kick off at 8am UK time

19:09 @mikegascoyne: Jarno went out on new tyres but stopped with another steering rack hydraulic problem. Lots of work tonight. Generally very good progress on setup direction today from Jarno. Long way to go but direction very clear

19:04 @clairevwilliams: We won!! Session ended just a couple of mins early as Alonso spun off, leaving the Hulk at the top of the charts

18:59 Session has been flagged off

18:59 It looks as though Alonso has caused the red flag

18:58 Just two minutes to go for someone to knock the Williams rookie off top spot

18:57 Schumacher in, just Alonso left on track

18:57 A bit of Ferrari humour. Clearly happy with their day...

@insideferrari: It is possible that some rabbits will be around as usual in the last minutes of the afternoon session

18:55 De la Rosa, Hamilton and Glock in

18:53 Into the last 10 minutes now. Hulkenberg still fastest, but is in pits. Alonso, de la Rosa, Schumacher, Hamilton and Glock still on track

18:52 Alonso in the 1m21s again

18:52 @mylotusracing: it's a wrap. we are done for 2day. will set the car up for tomorrow. weather f/cast for tmrw in now-sunny Barca, will be a chance of rain

18:51 @insideferrari: A very intense afternoon for Alonso. Race simulation completed successfully Now there is a lot of work for the engineers to analyse the data

18:49 Alonso, de la Rosa and Hamilton out at restart

18:48 It's definitely Trulli who has caused the red flag, but it's not clear why yet

18:43 It looks like it might be the Lotus again. Everyone else back in

18:42 Another red flag

18:42 Alonso into the 1m21s, 6 laps into run

18:39 ... and then goes in the pits. That's a couple of short runs since the session restarted. Qualifying simulation runs?

18:39 Hulkenberg does a 1m20.857s

18:38 Alonso and de la Rosa in 1m22s, but fuel levels unknown

18:37 @rf1paddockpass: Limited running this afternoon so we'll try the race distance later this week. Robert's still working on set-up.
