3. The Warsaw Meeting Hosted by PAS Space Research Center
Participants: Mike A’Hearn, Ivano Bertini, Björn Davidsson, Fiorangela La Forgia, Uwe Keller, Jörg Knollenberg, Michael Küppers (phone), Hans Rickman, Holger Sierks, Colin Snodgrass, Jean-Baptiste Vincent
Agenda: Overviews (CS - ground-based campaigns; HS - science operations repository; MK - flight dynamics), Science (MA - EPOXI; JBV - spin/activity; UK - lab experiments), Coma Observation Science Objectives (introduced by BD; discussed phase by phase; conclusions summarized in updated repository by HS)
Notes: taken by JBV and HR; Minutes prepared by BD, Nov. 2011

4. Action Items
Related to: early activity (overlap with nucleus studies); expected gas/dust production rates and exposure times; dust imaging/jet reconstruction; planning (number of exposures, timeline); filter selection
Results so far: spreadsheet with Q(gas), column density and surface brightness as function of projected distance from nucleus (MA) + modeled Af (CS); OSIRIS effective surface areas in WAC filters (JK); number of exposures vs data volume or shutter lifetime (BD); timeline (BD)
