Laboratory for Extraterrestrial Physics
Sun-Earth Connections Seminar
(aka Brown Bag Seminar)

About the Seminar

The Laboratory for Extraterrestrial Physics (LEP) at NASA's Goddard Space Flight Center conducts weekly science seminars. They are held on Fridays at noon in the Conference Room (Room 8) in Building 2 at Goddard. The topics cover the interests of the Laboratory, including astrochemistry, interplanetary physics, planetary systems, planetary magnetospheres, and electrodynamics. Since the seminar is conducted during the lunch hour, the audience often brings their lunch, hence the moniker "brown bag seminar."

    Year 2002





    Information for Speakers and Visitors

    Speakers interested in speaking at the Brown Bag Seminar are encouraged to contact the organizers, currently Nat Gopalswamy (301-286-5885, gopals@fugee.gsfc.nasa.gov) and David Sibeck (301 286-5998, dsibeck@pop600.gsfc.nasa.gov). The duration of the seminar is typically one hour, with questions asked during and after the seminar. The audience is usually diverse, including scientists with interests ranging throughout the heliosphere (see the Laboratory homepage for a list of interests).
