Teeminar (= German for Tea Seminar) is the group seminar of Silk Road Project at NAOC/KIAA, sometimes extended by visitors or talks from nearby institutes or disciplines.

Time and Place : weekly, Fridays 3:00-5:00 p.m. (sometimes other days), partly at NAOC, partly at KIAA/PKU. (How to find KIAA on PKU campus) (Location Map of NAOC)  . For more information please contact Rainer Spurzem.
