The TBS cam is obscured this morning by the weather. I believe it is raining in Fukushima. It is certainly very humid and the weather report called for rain.
The Tepco cam is showing lots of steam, which is typical when it rains. 'Spark' like phenomenon seem to be flying out of unit 3.
The white light that flashes on and off is back on again. I think it is on new construction on building 4 but it could be building 3.
The white light can be seen below on top of the small white box with vertical stripes to the immediate right of the large red-and-white crane
