Hello JT - Those are indeed reflections of camera lights bouncing off the protective housing our cameras are placed inside. Thanks, cheryl -------- JT Mayo Daniels wrote: What's going on with the green glow visible on the Great Sitkin Adak webcam overnight (March 1-2 2020)? It is also visible but dimmer in the GSIG webcam (upper left). I wouldn't think it would be the aurora, as that moves around a lot. I thought it might be a camera LED reflecting off of ice on the lens, but it shows up on two different cameras tens of miles apart and none of the other webcams in the network that I can see.
