I started watching the TEPCO and TBS cams at 12:00 am December 19 today, as time-stamped by the TEPCO cam.
I watched 8 hours with a two hour interruption. It was a very strange and alarming day. The heat signature visible on the TEPCO cam was clearer and larger than usual. The lights on the TBS cam were pulsing energy.
