Looks like they are talking about the 'lightning within x km of launch site' constraint, judging from the graphic.

Actually not quite, it's the anvil clouds rule. They are talking about the risk of struck by lightning during the flight into the cold front a la Apollo 12.

right sorry - what I meant
Some graphics on the launch sequence but I don't think they filled in the times, unless I missed it.

Under T-5 mins if they go for the opening of the window. Keep the screenshots coming if you're able.

LAUNCH! On time!

Can see it going through MaxQ, very pretty vehicle.

Looks like some serious wind shere there, based on the plume.

Hope that went ok. Froze for a while and came back to the remains of the plume and not much else.

Yay! My ustream.tv has frozen up, so appreciate the updates.

Interesting that the official JAXA press releases are identifying this as 情報収集衛星レーダ３号
"jouhoushuushuu eisei re^da 3 gouki" (IGS Radar-3) - my recollection is that the previous launches didn't officially identify the satellites as Radar or Optical, that just came from rumours.

Quite, for a few seconds there it looked like it was wobbling back and forth horribly and then keeled over - but after a while it reappeared. Phew!

Really amazing to see diffirent parts of the trail going off in diffirent directions so quick. Am I correct in assuming that we saw the launch from west of the pad, so that we looked onto the back of the vehicle as it flew onwards?

More like north-west: the rocket is going almost directly south (going for SSO)

Looks good!

Replay showed a longer version and it got to staging fine. Then went out of view due to range during second stage.

ah, allright, thanks.
Also, booster sep (barely) visible on the replay, I was too late to screenshot..

He said flight is nominal so far.

Great!

The guy talking on the webcast just said "high speed camera" for his slow motion views, so there's something I understood
