Preliminary results are presented of several “fan-shaped” jets within a flaring Active Region observed by IRIS and SDO/AIA. These jets occur at the edge of a sunspot and exhibit interesting dynamics such as demonstrating wave-like patterns during their phases of propagation on recession.Space-time plots have been produced across several channels, providing values for apparent speeds and accelerations. A spectral analysis of these jets was also conducted. Several mechanisms for explaining the observed dynamics of these jets are also proposed. These results are compared to those of Robustini et al. [1] and Reid et al. [2]. This study seeks to determine if a connection exists between these jets and foot-point brightenings and/or flaring events. Determining a correlation (if any) between these small-scale Chromospheric events and characteristics changes of the low Corona will clarify the connection between these solar layers.
