It seems not only is bright Moonlight sufficient to light the scene in the (north-looking) KPNO webcam, but also lightning will work, too. There happens to be an active cell southeast of the summit (10p Saturday night) that is providing illumination in about every other 1-minute image refresh. Will the south-looking camera actually catch a lightning bolt? http://www.noao.edu/kpno/kpcam/index.shtml \Brian -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
