  1. Hinode Coordinated Observations: Plasma Composition Linking solar wind with source regions using plasma composition. EIS Composition Map XRT Photospheric composition ~ 1 in coronal hole (CH) -> fastwind Coronalcomposition ~1.5-3 in active region (AR) -> slowwind Baker, Brooks, et al. 2013, ApJ 778, 69 Contributed by the Hinode/EIS team through the University College London / Mullard Space Sciences Laboratory

  2. Hinode Coordinated Observations: Plasma Composition Composition of sigmoid channel in erupting active region – topology clues? Sigmoid - XRT Sigmoid - EIS EIS Composition Map Inverse S-channel of photospheric material within the active region where significant flux cancellation takes place. A sigmoid/flux rope forms and erupts as a CME (Baker et al 2012). Scenario for build up of a flux ropewhere the bottom of the flux rope is located low down and has a Bald Patch (BP) topology(Green et al 2011 and Green & Kliem 2009). ->Space weather implications - allows identification of early build up of a flux rope and potential CME.

  3. Hinode Coordinated Observations: Plasma Composition Composition evolution in a decaying active region. Baker, Brooks, et al. 2014, in prep. From 4th to 6th January 2012, plasma composition evolves from coronal to photospheric in AR 11389 especially around supergranular cell boundary as repeated flux emergence supplies photospheric plasma to coronal loops via magnetic reconnection.
