Study of magnetic field configuration and its evolution, is an important aspect toward understanding the various solar activities happening in the solar atmosphere. In this context, we study a spiral like magnetic structure, observed with co-ordinated SST, IRIS and AIA observation, shows counter streaming flows on different 'spines'. Also, a classical 'X' like null point is present at the heart of this structure which beautifully manifests the complexity of this configuration . We analyse imaging data as well as the spectroscopic data to better understand and model such magnetic configuration and their evolution over time.
