As of midday it's now shakedown leader Fabio Quartararo back on top, from Alex Marquez, Fermin Aldeguer and Jack Miller.
While we were outside the medical centre, Fabio di Giannantonio fell next to us at Turn 5, the VR46 rider walked away unharmed.
Okay, we're back in the media room.
Jorge Martin's bike has been returned but the rider is in the medical centre after what was a huge highside and is currently undergoing checks.
Meanwhile the track action continues.
Turn 2 is the second, left-hand, part of the tight opener corners.
Jorge Martin has crashed again, this time at Turn 2. Red flags.
After his earlier spill, world champion Jorge Martin is back on track and looking to improve on 21st.
Franco Morbidelli has done the most laps so far at 22, followed by Jack Miller and Pedro Acosta on 18.
In other words, basically a full grand prix distance (but split into short runs this morning).
Franco Morbidelli jumps up to 6th, between Marc Marquez and Fabio Quartararo.
Gresini rookie Fermin Aldeguer is still the top GP24, and Ducati rider, in third behind the Pramacs.
Further down the order, Francesco Bagnaia is 11th at the moment and Aprilia world champion Jorge Martin 21st after his Turn 1 fall.
The current top ten:
Jack Miller (Pramac Yamaha)
Miguel Oliveira (Pramac Yamaha)
Fermin Aldeguer (Gresini Ducati)
Alex Rins (Monster Yamaha)
Marc Marquez (Ducati Lenovo)
Fabio Quartararo (Monster Yamaha)
Pedro Acosta (Red Bull KTM)
Luca Marini (Honda Castrol)
Augusto Fernandez (Yamaha test team)
Alex Marquez (Gresini Ducati).

Not a great surprise given they've already had two days at the Shakedown, but all four Yamaha race riders are in the top six at present.
11:20am and it's a Pramac Yamaha one-two with Jack Miller returning to the top, on a 1m 58.623s, putting him 0.294s ahead of team-mate Miguel Oliveira.
Johann Zarco, like Marini and Mir, did not ride at the Shakedown and is completing his first MotoGP laps of the year this morning.
The LCR rider has been out on two different Hondas, and is currently 12th.
New factory KTM rider Pedro Acosta rises to sixth place (+0.735s), the top RC16.
There's a sense of urgency here due to the weather.
It's overcast, windy, 'cool' (for Sepang) and there's a threat of rain at any moment.
Timing screens reveal that reigning world champion Jorge Martin has crashed at Turn 1. Rider OK.
No improvement by Marc Marquez during his second run, he remains in 4th (+0.327s).
Luca Marini pits, he's still in 6th. Marini is running the new livery but with the prototype black rear seat unit, without any winglets, used by Aleix Espargaro in the Shakedown.
Marc Marquez heads out for his second run.
The Factory Aprilia team has provided some good info on their plans this morning:
• Jorge Martín and Marco Bezzecchi will have three bikes available, for a total of six bikes in the box.
• The riders will start the morning with the first version of the RS-GP25 that was tested in Barcelona, before trying the RS-GP25 version that was later developed by the Noale Racing Department.
• The goal of the day is to facilitate the riders' adaptation to the bike, and then to focus on set-up, both mechanical and electronical. The day will continue with the testing of new components introduced in all areas.
• The test programme for the coming days is already set and will be updated on the basis of today's developments.
In terms of test riders, the only names on the entry list for the Official test are Yamaha's Andrea Dovizioso and Augusto Fernandez.
The other test riders seen at the Shakedown are thus not expected to return.
Again, a sign of the effort Yamaha is putting in.
Just over half an hour gone and Miguel Oliveira, who had a relatively quiet Shakedown in terms of timesheet position, puts his Pramac bike on top.
Rookie Aldeguer is second, Alex Rins third and Marc Marquez - now completing his first laps of the year - is in fourth.
