Out to check the early sky. It is pure cobalt, appearing entirely free of clouds for the first time in days. Oddly, it is also entirely free of stars. There were a few out, earlier, but now even those few bright lights which normally gleam well toward dawn have vanished. It could be that dawn will reveal a haze. If so, it is one of remarkable consistency. The entire dome of heaven looks as though painted with a single stroke of a giant brush. I've never seen it look so strange, or so utterly serene.
