Observations {#sec:obs}
============

The ARTB event under study occurred on 2014 March 4 at around 13:03 UT. The event was simultaneously recorded using multiple instruments such as the AIA and the Helioseismic and Magnetic Imager [HMI; @2012SoPh..275..207S; @2012SoPh..275..229S] both on-board the Solar Dynamics Observatory (SDO), EIS & XRT on-board Hinode, and IRIS. IRIS was operating in the sit-and-stare mode while EIS was rastering the region of interest. Figure \[fig:obs\] displays the AIA image taken in 171 [Å]{}. Over-plotted green and red boxes highlight the EIS raster and IRIS/SJI field of view (FOV) respectively. XRT field of view is indicated by an over-plotted dashed yellow box. The blue vertical line represents the IRIS slit position. The arrows mark the ARTBs, which are the subjects of this work.

In the current study, IRIS observations were carried out from 12:39:30 UT to 14:37:54 UT and covered the field of view of 119$\arcsec \times$ 119$\arcsec$ EIS raster was obtained between 13:02:20 UT and 13:20:23 UT and covered the field of view of 51$\arcsec \times$ 384$\arcsec$ using the 1$\arcsec$ slit. IRIS obtained spectra in the wavelength windows of lines 1335 & 1336 [Å]{}, 1355 [Å]{}, 1394 & 1403 [Å]{} whereas
