Coronal emissions and Doppler shifts seen in Fe XII. Left panel: AIA 193 Å region of interest. The upflow feature is located in the quiet Sun and highlighted by a blue contour. It is located in a low-intensity region. Within that region, a small brightening can be seen at the south-eastern end at around [115″, −730″]. The nearby vicinity does not show any structures that are typically associated with outflows, such as obvious jets. A white box indicates the field-of-view that is used for the two other panels of this figure. Middle panel: intensity plot of the Fe XII emission line from Hinode/EIS showing a similar structure as the corresponding AIA 193 Å image, but with lower spatial resolution. The bright feature at [115″, −728″] in the lower part of the Hinode/EIS image is more blurred and less intense than its vicinity in comparison to its AIA counterpart, where it is as bright as the brightest regions in the 50″×50″ field-of-view. Beneath it a small, rather dark region, is present. Right panel: derived Doppler velocities from the Fe XII emission line showing upflows, which is highlighted by the contour. The displayed blue contour is the zero-velocity line that divides regions of upflows and downflows. The strongest upflows are seen in the south-east with speeds of around −7 km s−1. Most of the vicinity shows downflows or comparably weak upflows.
