Wednesday

Active region 12673 produced a number of solar flares in September 2017, including the largest of solar cycle 24, an X9.3 flare on September 6th. The presence of sunquakes produced by this flare has already been reported on by (Sharykin & Kosovichev, 2018), however using Ca II 8542Å data form the Swedish 1-m Solar Telescope (SST), a co-spatial and co-temporal chromospheric component of one of these sunquakes has been detected. In this presentation I will describe the analysis of such a response, using the co-alignment of SST and HMI LOS data, as well as using the spectroscopic capabilities of the SST to investigate the line profiles of the wavefronts created by the sunquake. Finally, I will discuss the use of the NICOLE inversion code in helping us understand the creation of such a chromospheric response.
