That's all for now folks, but we'll be back on Saturday morning for at least five races on the north coast.
All eyes will be on Alastair Seeley - can the 'Wee Wizard' equal or even better Robert Dunlop's tally of success?

Tonight's win takes the Carrickfergus man level on 13 with Joey Dunlop and Michael Rutter.
It's over
Bad news - there will be no further racing tonight, so just two of the three events were completed.
However, organisers plan to run the Superstock race again on Saturday.

Byrne 'blown away' by NW 200
British Superbike Championship star Shane 'Shakey' Byrne is enjoying a first visit to the North West 200 and says he is "blown away" by the speeds achieved by the competitors.
"Total respect to the boys but I will stick to short circuits. I once did a parade lap at the Isle of Man TT in 2003 and I frightened myself to death," added the 38-year-old.
Post update
A Road Closing Order requires racing to finish by 21:00, so if we get a restart it will likely be over a reduced distance.
Post update
If the race is restarted it will be without Bruce Anstey - the New Zealander has decided to pull out because of a low sun, which is causing difficulties for riders.
Post update
The red flag was for an incident involving a rider in the second wave - organisers hope to get the race restarted.

Welcome back to our coverage of the North West 200. It promises to be a cracking evening of action with the opening three races of this year's meeting.
The weather is set fair on the north coast and we get under way at 18:00 BST with the Supersport race, followed by the Supertwins and Superstock classes.

That brings the action to an end for a few hours, but our live video and audio streams will be back at 17:45 BST for tonight's three races.
They are the Supersport, Supertwins and Supersport classes.

The final practice session is for the Superbikes and, because of earlier hold-ups in the schedule, has been reduced to a 35-minute run.
That will be it until the serious racing gets under way tonight at 17:45 BST.

William Dunlop is gingerly getting on to his Tyco BMW for the Superbike session.
The 29-year-old, who won in this category at last year's North West, was injured in an accident in Supersport qualifying earlier today.
He said he might not be able to race tonight - but here he is already back on the track.
They're a tough bunch, these road racers.
"I want to try to put in a time for Saturday," he tells Larry Carter on the grid.
"Tonight might still be a bit of an ask. I don't feel too bad sitting here but we will see what happens.
"I haven't broken anything and that is the main thing.
"I want to get a feel for the bike because we have not really had a dry run on it."
Post update
Phillip McCallen

Alastair Seeley has stamped his authority on the Supersport class, but he is not going to get it easy in tonight's race.
"Bruce Anstey in second and Michael Dunlop on a brand new bike will be in second place on the grid.
"Glenn Irwin is going to be one of the best newcomers. He is getting the track right and will be in the hunt tonight."
Quick question
As practice gets near to a conclusion, how about casting a vote in our North West 200 poll.
The question is, which rider will win tonight's Supersport race?
Use the voting buttons, and if you want the terms and conditions, handily
Red flag
The Supersport session is temporarily halted after William Dunlop comes off his Tyco BMW bike at York Corner. The local rider limps away to get treatment. Question is, will he be fit for tonight's racing action?
"I'm not too bad and am lucky I did not do more damage," he tells Stephen Watson.
"I might have to rest for Saturday if I'm not up to racing tonight."
Post update
Phillip McCallen
11-times TT winner
"Guy Martin is under pressure - he's doing movies, is tipped to be on Top Gear and seems to be on every TV channel.
"I think he is frustrated because things have not been going his way.

Asked if he can end Northern Ireland riders' domination of the Supertwins class, he said: "I hope so, I'll be trying that's for sure.
"There is no reason why we can't. Obviously Ryan (Farquhar) and Jeremy (McWilliams) will be there or thereabouts so it's about slipstreaming and planning your race. I have to use my head."

Post update
Veteran racer, if he doesn't mind me calling him that, Ryan Farquhar is catching the eye in the Supertwins. He quit racing a few years ago but made an impressive comeback last year. Flying Ryan tops today's qualifying times with an average lap speed of 106.536mph.
"I am leaner and fitter and I certainly have the experience. I think I am back to where I left off in 2012," said the 39-year-old KMR Kawasaki team boss.
"It is a bit breezy out there, but everything is going good. I have done a lot of development work on the bike and it is running spot on."
So Dungannon man Farquhar is on pole for the Twins and looking for his fifth career win at the North West 200.

The BBC Sport website will also have the live coverage from Radio Ulster medium wave, presented from a luxurious hut by Joel Taggart and Michael McNamee.
One to watch
Joel Taggart
BBC Sport NI
"Alastair Seeley is just three wins short of the all-time record of 15 career North-West wins held by the late Robert Dunlop.
"He has won five Superstock wins in his last eight races around here and at least one Supersport win in each of the last five years.
"But last year the Superbikes were dominated by the Dunlop brothers, William and Michael, who had one win each.
"Seeley will be looking make his mark there too."

Good morning from the North West 200. Thankfully it is a good morning, much better than the wet and windy conditions which greeted the riders for the first practice session on Tuesday.
We have another practice session this morning which will finalise the grid positions for the races which start tonight.
Tyco BMW rider Alastair Seeley from Carrickfergus is assured of a front-row slot in the Supersport and Superbike classes thanks to his exploits on Tuesday. The 'Wee Wizard' also had the best time in first qualifying for the Superstock machines.

They're a tough bunch, these road racers.
"I want to try to put in a time for Saturday," he tells Larry Carter on the grid.
"Tonight might still be a bit of an ask. I don't feel too bad sitting here but we will see what happens.
"I haven't broken anything and that is the main thing.
"I want to get a feel for the bike because we have not really had a dry run on it."

Alastair Seeley has stamped his authority on the Supersport class, but he is not going to get it easy in tonight's race.
"Bruce Anstey in second and Michael Dunlop on a brand new bike will be in second place on the grid.
"Glenn Irwin is going to be one of the best newcomers. He is getting the track right and will be in the hunt tonight."
Quick question
As practice gets near to a conclusion, how about casting a vote in our North West 200 poll.
The question is, which rider will win tonight's Supersport race?

Red flag
The Supersport session is temporarily halted after William Dunlop comes off his Tyco BMW bike at York Corner. The local rider limps away to get treatment. Question is, will he be fit for tonight's racing action?
"I'm not too bad and am lucky I did not do more damage," he tells Stephen Watson.
"I might have to rest for Saturday if I'm not up to racing tonight."

"Guy Martin is under pressure - he's doing movies, is tipped to be on Top Gear and seems to be on every TV channel.
"I think he is frustrated because things have not been going his way.
"He is trying hard but he will have to settle, focus and get into the right frame of mind."

Guy lets fly
Everyone is having a great time at the North West 200 apart from, it seems, colourful competitor Guy Martin.
The outspoken Lincolnshire racer has a rant on the BBC about the chicanes on the Triangle circuit, declaring himself "bored to the back teeth" during practice for the Superstocks.

Hillier confident
Hampshire's James Hillier is confident he can become the first English winner of a Supertwins race at the North West. He was fastest in Tuesday's practice and will be on the front row after another good showing on Thursday morning.
Asked if he can end Northern Ireland riders' domination of the Supertwins class, he said: "I hope so, I'll be trying that's for sure.
"There is no reason why we can't. Obviously Ryan (Farquhar) and Jeremy (McWilliams) will be there or thereabouts so it's about slipstreaming and planning your race. I have to use my head."

4. Jeremy McWilliams 105.68
5. Jamie Hamilton 104.85

Post update
Veteran racer, if he doesn't mind me calling him that, Ryan Farquhar is catching the eye in the Supertwins. He quit racing a few years ago but made an impressive comeback last year. Flying Ryan tops today's qualifying times with an average lap speed of 106.536mph.
"I am leaner and fitter and I certainly have the experience. I think I am back to where I left off in 2012," said the 39-year-old KMR Kawasaki team boss.
"It is a bit breezy out there, but everything is going good. I have done a lot of development work on the bike and it is running spot on."
So Dungannon man Farquhar is on pole for the Twins and looking for his fifth career win at the North West 200.

It's sunny

"The weather is much better and there was a sense of excitement walking into the paddock this morning.
"The sun is out and, according to the weather man, it is going to stay out so we should be in for a great day's racing."
Post update
Coverage of the practice sessions starts at 09:40 BST with live video streaming presented from the grid by Stephen Watson who will be with another North West 200 legend Phillip McCallen!
In 1992, McCallen won five races out of six at the North West 200.
The BBC Sport website will also have the live coverage from Radio Ulster medium wave, presented from a luxurious hut by Joel Taggart and Michael McNamee.
One to watch
Joel Taggart
BBC Sport NI
"Alastair Seeley is just three wins short of the all-time record of 15 career North-West wins held by the late Robert Dunlop.
"He has won five Superstock wins in his last eight races around here and at least one Supersport win in each of the last five years.
"But last year the Superbikes were dominated by the Dunlop brothers, William and Michael, who had one win each.
"Seeley will be looking make his mark there too."

Starting soon
Good morning from the North West 200. Thankfully it is a good morning, much better than the wet and windy conditions which greeted the riders for the first practice session on Tuesday.
We have another practice session this morning which will finalise the grid positions for the races which start tonight.
Tyco BMW rider Alastair Seeley from Carrickfergus is assured of a front-row slot in the Supersport and Superbike classes thanks to his exploits on Tuesday. The 'Wee Wizard' also had the best time in first qualifying for the Superstock machines.
