Triangulation of CME Source Region Locations on the Sun and Dependence on Spacecraft Observation Angles

Temmer, M.; Hanslmeier, A.; Preiss, S.

STEREO-A, STEREO-B, and LASCO/SOHO observe coronal mass ejections (CMEs) from three different vantage points. On the basis of the radial plane-of-sky (POS) measurements of a CME in these three projection planes, the CME source region (SR) location was determined using the triangulation method of Temmeretal2009. As this triangulation method needs d…
