I. Travel times provide constraint on magnetic field topology

4 mHz

- B inclination angle

7 mHz

- ~1 surface107 hours of Na & KData from South Pole

II. Seismology

Dispersion curves should allow identification of wave type

III. Wave contribution to dynamics of upper atmosphere

EIT 19.5 nm - “Event” 4 mHz - “wave travel time”

QuickTime™ and aMPEG-4 Video decompressor

are needed to see this picture.

Detect magnetic reconnection?

“Monitoring the chromospheric energy flux”

107 hours of South Pole data

“Acoustic Portals”

Multi-colored overlay of 3(red), 4(green), & 5(blue) mHz PTTs

• 3minute running waves leaking from sunspot umbra. Progression to lower frequencies (5minute) visible in the penumbra. “coronal” wave leakage.• “acoustic portals” on SG boundaries. • “rainbows” in SG interiors advected magnetic dipoles?

Need: full disk, long duration obs. In B, V and I

Potential overlap with Coronal Seismology
