Mercedes:, external Heads up! Nico Rosberg knocks it outta the park with a century of laps! And he's not done yet - 1hr 20mins left...
It is pretty quiet out on the circuit with Daniil Kvyat, Felipe Nasr and Nico Rosberg cranking up the lap count. Rosberg is closing in on 100 for the day.
Lotus:, external Success for Romain Grosjean in the 'go fastest' simulation.
No messing about from Romain Grosjean. He puts his foot on the pedal and slings the Lotus round the circuit in 1:24.681 to go fastest of all today.
Just like before, it is Daniil Kvyat and Romain Grosjean champing at the bit to get back out and they do so immediately, with Nico Rosberg and Felipe Nasr joining them.
Green flag and we are go again with 90 minutes left.
Valtteri Bottas' Williams came to a halt at Turn Four, three minutes after the circuit had gone green.
And another red flag, this time for Valtteri Bottas it would seem.
Daniil Kvyat, Romain Grosjean and Valtteri Bottas are the first to return to the circuit with just over 90 minutes left of the final day of the second test.
Carlos Sainz's Toro Rosso has been dealt with and the circuit is green again.
McLaren confirm there will be no outing for Jenson Button this afternoon, but the main thing is that Fernando Alonso is uninjured after the earlier accident.
McLaren:, external "That's the end of our programme here at the first Barcelona test. Thank you for all your messages of support for Fernando."

"Scans taken at the hospital show that Fernando Alonso has no injuries, a McLaren spokesperson says. It not yet decided if he will remain in the hospital overnight."
F1 journalist Dan Knutson in Barcelona: "For most of the day the wind was blowing between 10 and 15 km/h, but now it has died down and is blowing between 0 and 5 km/h.
"The cars will be more stable on the track now, and things are more pleasant for the spectators in the afternoon sun."
No more running from Force India today then.
While we wait for more information on this stop, Force India say Nico Hulkenburg's car stopped earlier because of a power unit issue which they will "investigate back at the factory."
Another red flag, with Carlos Sainz stopping at Turn Three in the Toro Rosso.
Felipe Nasr, also on the soft compound, improves on his 26th lap of the day as a 1:25.487 moves him up to second, 0.546 off Daniil Kvyat's benchmark effort.
Rapid from the Red Bull as Daniil Kvyat, on softs, flies around the circuit in 1:24.941 to go top of the timesheet. That's six tenths off the fastest time of the whole test, set by Pastor Maldonado on Saturday.
F1 journalist Dan Knutson in Barcelona: "Valtteri Bottas' long run has been interrupted by planned visits to the Williams garage and the red flag for Nico Hulkenberg. He started on the soft compound Pirellis and switched to the medium slicks for just one lap before the scheduled stop in the garage. He then headed out on the hard compound slicks and had done 30 laps of the run before the red flag. He's out there again now and still on the hard tyres."
