Nice. I scrolled back in time; there were some periods overnight when the fountain was much higher. I went all the way back to around the time of local sunset to see when it really got going. As it gets dark, you can see it glowing inside the fissure, but then suddenly in the lower left the actual outward flow of lava starts to be visible, at about 18:25 local time.
Here’s the link again so you don’t have to hunt for it.
