The chequered flag is out, and it's Nicolo Bulega who has taken pole position, and is the only rider in the 1:47s. Alex Lowes had crashed at turn five but seems to be okay, he's qualified sixth, but it's and all-Ducati front row with Iannone and Bautista alongside Bulega.
Razgatlioglu up to fifth with this latest lap, almost half-a-second off Bulega.
And there's a lap record. No SCQ tyres this weekend but Nicolo Bulega didn't need one to do a 1:47.840, and he takes pole position as Danilo Petrucci moves up to fourth place in his wake.
Riders heading back out now for their second runs, and it's still Iannone's 1:48.208 to beat.
Nicolo Bulega gets onto the front row with his first lap in third place. Toprak Razgatlioglu's first lap put him seventh, but he's only 0.202s off the pace.
Andrea Iannone sets the early benchmark at a 1:48.208, and Alvaro Bautista slots in behind him in second place, 0.050s adrift.
Superpole is now underway in Aragon, and the riders are filtering out onto the race track.
We're just under two minutes away from WorldSBK Superpole in Aragon. Conditions look fairly perfect on what is a freshly resurfaced MotorLand Aragon layout.
