Friday I drove down to the Center for Atmospheric Research at UMass-Lowell to give a seminar on auroral ion acceleration.
The Center for Atmospheric Research takes up most of the third floor of one of the old mill buildings in downtown Lowell. There are many interesting things you can do with a space like that. It's also a sign that Lowell is relatively well off as old New England mill towns go--the successful ones have been able to recycle the mill buildings into office/commercial/industrial space. (Compare Lawrence, a short distance up I-495: they haven't done so well recycling their mill buildings, and they are chiefly known as the primary heroin source for northern New England.)
The seminar went well, with lots of questions and some good discussion of the topic.
