[8.02] Localized Frequency Shifts from GONG+

R. Howe, R.W. Komm, F. Hill, John Bolding, Cliff Toner, Thierry Corbard (NSO)

Ring Diagram analysis uses 3-dimensional power spectra from small areas of the solar disk to measure the local frequency of high-degree modes and follow local flows below the surface. The pipeline for processing ring diagrams from the 1024\times 1024 pixel data generated by the GONG+ network has now been implemented and the first data has been analyzed. We will present our latest initial results on the local variations in the mode frequency and their correlation with the local magnetic index over a month or more of observations.

RK, CT, and RH in part, are supported by NASA contract S-92698-F. NSO is operated by AURA, Inc under a co-operative agreement with the National Science Foundation.
