That would be bright

I haven't been following closely, I think it is still increasing in bightness isn't it? (It's not just my 12.2 is an error?).

It sometimes takes me a while to catch on to these events, but I have now scripted it in my nightly script, so it will be interesting to graph the brightness over it's life span at the end.

Roger.
