1402: The McLaren driver finds the pace just when he needed it most and takes his fifth pole position of the season as he clocks 1:46.887 to steal pole from Massa. Hamilton's team-mate Kovalainen squeezes Raikkonen out of third spot into fourth. Heidfeld takes a very decent fifth for BMW Sauber ahead of Alonso's Renault. Webber will start in seventh for Red Bull with Kubica eighth in the second BMW.
"Ferrari are slightly on the back foot but the two title contenders are on the front row - so expect a battle royal on Sunday."
BBC Radio Five Live analyst Maurice Hamilton
1401: Hamilton takes pole for the Belgian Grand Prix.
1400: Massa sets provisional pole in 1:47.638 but how long will it last? Hmmm it's not looking good for the Brazilian.
1358: It's all or nothing for Massa now on his last flying lap. The Brazilian is looking quick but behind him Hamilton is going even quicker.
1356: Things do not go according to plan for Ferrari as Raikkonen is third fastest after the first run and Massa is down in fifth. McLaren are taking the fight to Ferrari with both Hamilton and Kovalainen driving aggressively. They've locked out the front row as things stand.
"McLaren have got the measure of the Ferraris."
BBC Radio Five Live analyst Maurice Hamilton
1354: Massa clocks 1:48.666 - looks like he made a mistake in the final section. The Brazilian is soon overhauled by Raikkonen and then Hamilton, who climbs to the top with 1:47.973.
1352: "It's a matter of how well the cars go in the middle sector in Spa and whether the Ferraris need to put more downforce there - that may cost them time. But there's very little to choose between the McLarens and Ferraris so it should be fascinating."
Radio Five Live analyst Maurice Hamilton
1350: Right we're off then and Massa is getting straight down to business, first out of the pits.
1349: By the way, Hamilton can rest easy on the rain front - though he is pretty handy in the wet - because no rain is forecast for the rest of qualifying. It hardly merits a sun graphic I know, especially as the crowd in Spa are snuggled up in their waterproofs but I do love a bit of sunshine.
1347: "I reckon it's engines and traction that are dictating the pace here - that points to the Ferraris I think being top."

1344: We have our final line-up of drivers who will battle it out for pole; but those that miss out are Rosberg (Williams), Coulthard (Red Bull), Glock (Toyota), Piquet (Renault) and Trulli (Toyota). Now that's unusual for the Toyotas who have been enjoying a good run in qualifying but they have been struggling in the cooler track conditions.
1340: Those in the danger zone at the minute are Rosberg, Coulthard, Trulli, Webber and Glock. It looks like both McLarens and Ferraris are staying in the garages while the rest of the pack go out again.
1338: Hamilton says on his team radio that the bottom end of the track is looking a little dark. Is rain on its way?
1337: Kubica completes his first flying lap but it's pretty untidy. He locks up at the Bus Stop and crosses the line in sixth. His BMW Sauber team-mate Heidfeld is the only other man out on the track as the rest of the drivers prepare for one final flying lap.
1333: Kovalainen overhauls the Ferrari man with 1:46.037 and team-mate Hamilton cannot match him after a little wobble on the final turn.
1332: Raikkonen sets the fastest lap of the weekend in 1:46.960. The track is really starting to heat up now - and there's no sign of rain.
1329: Guess who's first to the qualifying party this time? It's only Kimi Raikkonen - surely a man who loves a party.
1328: "I think a Ferrari 1-2 is still on the cards, but I hope there is rain just to keep things lively."

1327: Green lights are go for the second session. Who'll go out first?
1324: Sebastian Bourdais lays down a hot one to surprise us all quite frankly as he jumps to the top of the standings in 1:46.777. He responds with a loud "Woooo-hoooo" over the team radio. No cheers at the opposite end of the timesheets as Fischella (Force India), Nakajima (Williams), Sutil (Force India), Button and Barrichello (Honda) all go out.
1320: The drivers from six down to 20th are all out in the track desperately trying to get out of trouble. Webber puts the pedal to the metal to haul himself up from 17th into eighth while Red Bull team-mate David Coulthard climbs into sixth. That'll change in a minute though.
1319: Massa is out on the hard tyres for another run round Spa while those at the bottom of the pack are trying to find some extra pace on the softer options. Massa sets a fast first sector but cannot improve on second after losing time in his middle stint.
1316: Kovalainen goes to the top of the tree as he sets the fastest lap of 1:46.812. Do you reckon the cool temperatures are working in McLaren's favour?
1314: Six seconds to go and time to have a quick peek at those in the drop-zone. Propping up the standings is Nakajima for Williams; apparently he's losing a second in the middle sector so that's the root of his problems. Button and Barrichello (Honda), Fisichella (Force India) and Red Bull's Mark Webber are also in trouble. That's very unusual for Webber.
1311: Hamilton is back in the garage. Presumably it's job done for the boy from Stevenage. Meanwhile on the track, Raikkonen closes to within a tenth of a second of Hamilton as he brings his Ferrari into second ahead of team-mate Massa.
1308: Ahh they must have been good vibrations because Hamilton only goes and sets the fastest time of the weekend to jump to the top of the standings. He clocks 1:46.887 and Massa cannot match it as he crosses the line more than a second adrift for Ferrari.
1306: Lewis Hamilton wheels his McLaren onto the looping Spa circuit but it's not the best of starts for the championship leader as he reports on the radio a problem with his wheel balance. Apparently he's having vibrations - let's hope they're good ones.
1304: Piquet sets the first meaningful time in Spa, clocking 1:48.727 for Renault. The Force Indias and the Hondas are also out on the track.
1300: Off we go then. I do like Nelson Piquet, because you can always rely on him to get out early and he's at it again in Spa. I bet he's the sort who turns up to a party on time with a nice bottle of plonk and some pretzels.
1258: Ah-ha Darrell to quickly answer your question (1248) the last time qualifying was wet in Spa was back in 2004. Qualifying for the Japanese Grand Prix was pretty damp and foggy too at Fuji last year.
1255: Fluctuating weather in Spa. The temperature is a mediocre 17C and it is pretty windy too, but it's dry overhead though a patch of showers are close by.
1248: "Fantastic qualifying session ahead, bring on the rain I say, by the way when was the last time a qualifying session was wet?"

1244: It's no secret that Ferrari really want to push their title challenge in Belgium and what happens this weekend could have an impact on which driver they favour going into the final five races of the season.
Massa is six points adrift of McLaren's Lewis Hamilton and, after setting the fastest lap of the weekend so far on Friday, he's looking strong again in Spa. Raikkonen, who is 13 points off the lead, is gunning for a fourth consecutive victory at the Belgian Grand Prix but his Friday saw him lose his rear wing and there were more wobbles in final practice.
Raikkonen's engine blew last time out in Valencia but the team are confident they have resolved their problems after a spell of testing in Monza. But at a track that demands full throttle for pretty much most of the lap, its all fingers crossed in the Ferrari pits.
1236: "It's one of those where you don't know what could happen but my predictions are: 1. Massa 2. Hamilton 3. Kubica."

1235: Final practice was dampened by a smattering of rain early on and the drivers were out trialling the grip on the wet, intermediate and then the soft tyres as the racing line began to dry up.
Nick Heidfeld clocked the fastest lap of one minute 47.876 seconds for BMW Sauber. The German team haven't finalised their 2009 line-up yet and his hot lap will be a fillip for Heidfeld, who needs to raise his game after a dip in form.
1225: Hello there. It's Saturday and what could be more relaxing on the weekend than a trip to a spa, sorry, Spa.
The Belgian Grand Prix is staged at the longest circuit in Formula One at 4.35 miles with plenty of fast corners, slow corners, ups and downs and sweeping runs through the Ardennes Forest.
And if you thought the British were obsessed with discussing the weather how about the good folk of Spa?
The weather is so unpredictable that there's an old adage in F1 that it can be raining at one end of the track and sunny at the other.
But what will all this mean for qualifying - who will master the changeable conditions and take pole?
