I have a question for the geological/meteorological savvy on this list. I just read a couple of short articles on MSN were Peru's Mount Ubinas and Ecuador's Tungurahua volcanos have had recent eruptions. Mount Ubinas has been active since September of 2013 and Tungurahua has been active since 1999 with the last major eruption happening on February 1 of this year. My question is; can the ash clouds from either, or both, migrate to the mid-northern latitudes as they circle the Earth? Is there a web site that posts the predicted/actual paths of these ash clouds? And last of all; what, if any, effect could one expect as far as the Danjon scale of lunar eclipse brightness (say L=3 as opposed to a L=1 level of brightness)? Would it be safe to say, "the darker your location, the better," for this eclipse? Just curious. Tom Sevcik
