Emerging Active RegionsDeep focusing travel time maps ofthe Active Region 10488 The focusdepth for these measurements covers40-70 Mm. The color scale in thetravel time maps covers theperturbation range 0 (blue) to -15(red) seconds.The maximum time shiftmagnitude is observed at around1:30 UT, October 26.The magnetic fields before and afterthe emergence time and thecontinuum image for a later time arepresented in the last three panels ofthe bottom row.Courtesy of Shukur Kholikov (Solar Physics accepted)
Ø Far-side seismic mapsSummary• Already used as a space weather tool• Improve stability of signal and detection capability.• Encouraging results when using as input to solar models for spaceweather in case studies.Ø Flare activity and subsurface flows• Statistical analyses show potential• Need to be investigated for individual eventsØ Predicting the emergence of active regions• Encouraging and interesting initial results• Work in progress…..
