(b) Intensity, (c) Doppler velocity, and (d) line width in the Fe XIV (264.7 Å) line observed by Hinode/EIS. The start time of the scanning is 07:17:59 UT on 2017 September 6, and it takes approximately 3 minutes to scan from the west to east (right to left) in the field of view. The color scales for intensity, Doppler velocity, and line width are depicted on the right. Panel (a) is a reference B_z magnetogram observed by SDO/HMI SHARP at 06:00 UT on 2017 September 6, which is closest in time to the Hinode/EIS observation of panels (b)–(d). The intensity, Doppler velocity, and line width maps and B_z magnetogram are co-aligned with each other, and the green colored magnetic polarity inversion lines in panel (a) are overplotted on panels (b)–(d) denoted in red, black, and white lines, respectively. Temporal evolution of the small cusp-shaped brightening in panel (b) is depicted in panels (e)–(i), which are coronal images captured by SDO/AIA 171 Å in the field of view of the red rectangle in panel (a). The cusp-shaped brightening in panel (b) starts as a tiny brightening that is indicated by the white arrow in panel (e).
