| Abstract: |
The high temporal relation data obtained from EIS/Hinode has been analyzed. In the ‘sit-and-stare’ mode observations,
we focused on continuous outflows at the edge of the active region NOAA 10942 on 2007 February 20. We found that
the Doppler blueshift (∼20–50 km s-1) components, in Fe XII 195 Å emission line, propagating with the continuous
plasma outflows from the edge of the active region, with the transverse velocity ranging 140–160 km s-1. This suggests
slow magnetoacoustic wave propagation along the open field line. We also found a jet around the active region, whose
transverse velocity ∼170 km s-1 and line-of-sight Doppler velocity ∼150 km s-1. |
