I always have the stream running in the on one of my monitors just to keep an eye on the situation. And I noticed about 20 minutes ago a fairly large amount of smoke was coming from reactor 4, and slightly less from reactor 3.

While I was waiting to see if anything more major would happen from this they started dimming the lights on the plant and then completely shut them off making the plant unviewable by the camera since it's night there.

You can sorta see the smoke in this camera on the tepco site which updates with still images: [link to www.tepco.co.jp]

I'll look to see if any news stories come up about it over the next few hours.

(while I was typing this I noticed the lights flicker back on for a few seconds and the smoke was still coming from reactor 4)
