Here we have seen oscillation in a solar on disk plume structure near coronal hole with high spatial and spectral resolution of IRIS. There are several reports of oscillatory signature in plume region from SDO/AIA data. We have analysed 1 hour 24 minutes sit and stare data taken with 5 second raster cadence and 5.1 second step cadence by IRIS. The data is taken on 2014-07-12 from 16:27:08-17:51:29 UT. We have done spectroscopy with far-UV line Si IV. IRIS has 40 mA spectral resolution in far UV line. With this high resolution we have seen in dopplerogram clear signature of oscillatory motion. |
