Here are the times at the end of the Pole day qualifying session, which also determines pit stall order for the race. The order of positions 10 through 24 are set; those who did not make it in on Saturday start afresh on Sunday for positions 25-33.
The drivers on the first three rows now have their times deleted and have 90 minutes to set new ones to determine the order of the front three rows, rather like the way Q3 works in F1 qualifying.

Update at 9.10pm BST (4.10pm Indiana time):
When the track reopened following Ed Carpenter's big crash in turn 2, it was Sebastian Saavedra's turn to try a qualifying run after blowing up his Chevy engine earlier in the day. The run was looking good until a small bobble on the third of the four timed laps ducked his aggregate down to 221.217mph and outside the top 24.
Mike Conway was next out on track, attempting to undo the problem of failing post-qualifying technical inspection for being underweight during his first run. He managed a four-lap average of 222.434mph, well down on his initial qualifying run of 223.160mph but still 0.019s faster than Bourdais who was bumped out of the top 24 as a result.
Conway's place in the qualifiers lasted just a few minutes, before the next man out - Dale Coyne Racing's James Jakes - went comprehensively faster with a lap speed of 223.482mph to slot into 17th position and bump Conway out of the top 24 and now leave Wade Cunningham on the bubble.
Sebastian Saavedra took up the challenge, and proved up to the task with an average lap speed of 222.811mph even as the gunshot rang out to call time on the qualifying session. Conway didn't get his own chance to respond: even though he had lined up ahead of Saavedra, the team had tried to carry out a craft tyre change in the tech inspection line which wasn't allowed. The car was pulled out and lost its spot and had no time to re-queue.
Those who didn't qualify in the top 24 today - Wade Cunningham, Mike Conway, Sebastien Bourdais, Bryan Clauson, Ed Carpenter, Katherine Legge, Oriol Servia and Jean Alesi, who made no attempt at all to run on Saturday - will still be able to make the grid on Sunday assuming they have raceable cars.
None of these late runners affected the top nine going through to the 90-minute pole shootout from 4.30pm, consisting of: James Hinchcliffe, Will Power, Ryan Hunter-Reay, Helio Castroneves, Ryan Briscoe, Tony Kanaan, Marco Andretti, Josef Newgarden and EJ Viso. Rubens Barrichello was left the first man on the outside looking in.
Update at 8.35pm BST (3.35pm Indiana time):
Practice was brought to an end and qualifying resumed with around 50 minutes to go with Sebastien Bourdais lined up to make his second attempt at qualifying after waiving off his first run. He completed his run with an aggregate lap speed of 222.415mph to get into the top 24.
His run was followed by a new attempt by the #99 of Wade Cunningham who had withdrawn his earlier time in order to make a new run. His new run gained an average lap time of 223.134mph to go into 19th place, a considerable improvement on his earlier withdrawn lap of 221.514mph.
