Detecting sun-quakes using GONG data

Publication date:

Two papers on detection of sun-quakes using groundbased Global Oscillation Network Group (GONG) data are now published in Astrophysical Journal. The first, develops specific cleaning techniques for GONG velocity data and shows that it can be used for quake detection by comparing the results with those obtained from spacebased SOHO-MDI mission. In the second, a new sun-quake associated with 2006 December 14 X class flare is reported and analysed.
