Illustration of a successful linkage between a CME observed in white-light on STEREO-A on 3 June 2008 (panel e) with subsequent in situ signature at STEREO-B on 7 June 2008: the top panels show (a) plasma beta, (b) total plasma pressure, (c) number density from 2 to 7 June 2008 measured at STEREO-B. Middle: STEREO-A elongation-time J-map combining HI-1 and HI-2 running difference images. The vertical dotted lines mark the extent of the ICME signature in the STEREO-B data. The ICME boundaries closely match the region bounded by the leading and trailing elongation-time tracks in the STEREO-A data (black arrows). Bottom panel: one of the HI-1A running-difference images employed to build the J-map. From Rouillard (2011). Reprinted by permission of JASTP.
