Peter Gallagher on RHESSI-CDS Joint Observations

  • CDS March 26 event: 5 min cadence with excellent morphology in five bands plus TRACE
  • Pixon maps post impulsive phase; spectrum of loop top with nice Fe feature - discussion of Pixon behavior (Metcalf)
    - discussion of what is real and what is not real - "if you are interested in extended sources, you should not use high resolution collimators"
  • Cooling sequence via time delays, conductive or radiative?
  • Properties of event
    - Is there multi-thread structure? Laplacian filtering of post-flare loop image [Note that laplacian.pro has disappeared from SolarSoft!] - Nice movie and flow plots (120 km/s) suggest filament-like flows associated with the impulsive phase of the flare, emanating from near one footpoint but perhaps consistent with a coronal origin
    -Strong emerging-flux signatures
    - Interesting dimming properties? But no obvious CME-type expansions in the TRACE images. Spine-type geometry?
    - "Certainly the best CDS..." flare event?
