Proposal: Use AIA data to study wave behavior in atmosphere
Requires: Images every 10 (20) seconds
Wave studies with AIA
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
“Monitoring the chromospheric energy flux”
“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
