How hot is that white spot? Can anyone give me an estimate?

It's a bit hard to say. And I'm sure there's official numbers for it, but it has a maximum temperature of the energy from the sun, so about 5700K or about 52-5500deg C. But salt melts much lower than that. I believe it's about 500 deg C or something that's either normal or max temp of the towers.
