We are proposing for a new Hinode SOT SP observation in order to support our research, and a soon-to-be submitted NASA proposal (HSR deadline of Oct 30th) regarding the identication of MHD waves and their amplitudes, frequencies and propagation. The NASA HSR proposal has myself as PI, Paul Cally, Paul Rajaguru, Charles Baldner and Phil Scherrer as investigators. We plan to use Cally's numerical simulations of acoustic wave conversion into MHD waves to guide our observations and interpret the results. We will utilize local helioseismology of the observed sunspot in HMI data to determine acoustic mode absorption. We will use HMI 12-minute vector magnetic field maps for the average and general geometry of the field in the vicinity. We want to analyze the SOT SP data to examine what temporal variations exist in the inverted data and Stokes vector that could be informing us of the existence and nature of MHD waves. Optionally, we would like to include IRIS data of Mg II, C II and Si IV lines to correlate with the Doppler and magnetic fluctuations observed in SP. |
