>> The sky Saturday was a deep blue during the day. The wind changed a bit late last week, so the smoke that had been present regionally had blown somewhere else, so we didn't have much crud (that's the technical term) in the lower troposphere. In the last 24 hours the winds have been more southerly, so it's very cruddy this evening. >> The moon was exceptionally bright. The moonlight was >> brighter than I have ever seen it up there.... The old-same Moon of course, but contrast makes a lot of difference to the eye. The amazing (and deeply satisfying) thing in the last several nights has been _after_Moonset_ right up into morning twilight, about 3.30a. I've just been gaga staring at the sky then. I mean, the rational facts are easy enough to describe, but there's some psychological thing about having the Milky Way dead overhead (set your desktop planetarium for 20h sidereal time), the early-winter constellations just about to come up (the Pleiades just up during twilight), the dead silence at Anderson Mesa, the first bird twittering in the distance... can't even pretend to explain it. \Brian -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
