Most riders back in the pits now as Ogura moves up to second - good session so far for the rookie.
Bit of an off for Martin at 9/10/11, just a run through the gravel.
Marquez, meanwhile,has got himself back to the top on a 1m18.663s. Morbidelli now seconds ahead of Di Giannantonio, then Vinales fourth ahead of Bezzecchi.
Crash for Luca Marini at turn one. He's walking away.
Di Giannantonio now to the top. He leads Marc Marquez and Martin. Alex Marquez still in fourth, then it's Bagnaia and Morbidelli in the top-six.
Crash for Alex Marquez, just lost the front into turn four. Very frustrated with himself for that because he's losing key dry track time now.
Times scrolling hastily early on here, as you'd expect given the state of the track, which is still patchy but drier than it was at any point yesterday.
Marquez down now to a 1m18.911s and leads Alex Marquez by just over a tenth.
Marc Marquez with the early benchmark, a 1m20.372s to put him just under a tenth ahead of Bezzecchi, then it was Acosta but Quartararo has just popped up to third himself.
Conditions are as dry as they've been this weekend in Goiania this morning. Should be an important FP2 session, therefore, as riders try to dial themselves in to this new layout as well as understand tyre wear before the Sprint later on.
27C air temperature, 38C track temperature at the start of this 30-minute session.
Welcome to live coverage of today's MotoGP action from Goiania.
FP2 will be starting in just a couple of minutes. Qualifying is due to get underway at 10:50 local time, so in just under 50 minutes.
