There are exceptions, however. I wasn't expecting it to be clear this morning, but when I awoke, Jupiter one of the few "stars" that I can see even without eyeglasses was shining through the bathroom window. So I decided to take a quick look at nearby Nova Scorpii 2007, which I had observed from the same spot just five mornings earlier. Epsilon Scorpii, the jumping-off star, was too low in the light-pollution soup to be visible naked-eye, but it was easy to locate with my 10x30 binoculars, even through a window and storm window as was Nova Scorpii 2007. Having spent some time memorizing the field on my previous observation, it was immediately obvious that the nova had dimmed about a full magnitude.
So I put away the binoculars, having spent all of two or three minutes on this little project. But it's good that I did it right off the bat, because by the time I'd finished breakfast, the sky had clouded over.
