“Laissez-Rouler Le Bon LLBL!”



Eighty scientists gathered at a Chapman Conference in New Orleans last spring to discuss the low-latitude boundary layer (LLBL) and its dynamic interaction with the solar wind and magnetosphere. The topic was more narrowly defined than for most previous Chapman Conferences, as this one specifically treated the LLBL. However, the turnout was respectable, albeit in part because many attendees ventured into neighboring issues— notably merging—that have dominated previous meetings, such as the 1994 Chapman Conference on the physics of the magnetopause. Discussions were unusually lengthy and lively; fortunately, they were conducted with little rancor. A highlight of the meeting was Tim Eastman's historical review of early LLBL research, which established when certain terms first entered the literature. “LLBL” was first used by Gerhard Haerendel and colleagues in 1978, although observations of this region had been made earlier.
