Since the winds are generally from the southwest, the south-facing webcam gets a lot of moisture, ice, etc compared to the more sheltered north-looking one (on the east side of the 2.1-m dome). So the window or casing it is in needs cleaning a lot more often, and I doubt doing that is very high on anyone's priorities there. \Brian -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
