Abstract: From observations of 37 flare-arcade events, their magnetic settings, their sheared core fields, and the coronal mass ejections from these events, we find evidence that the sheared core fields in mature magnetic arcades are not formed by bodily emergence of a twisted flux rope along the neutral line. This implies that these sigmoidal sheared fields are instead formed by reconnection and flows above and in the photosphere. A high priority of Solar-B should be to discover the evolutionary processes that build the sigmoidal sheared fields along mature neutral lines.
