Notes from Wednesday presentations

Fletcher

-White: why should people fuss about filter ratios? OK
-Cargill, Hudson, White: Bradshaw work... there are real problems. He is
 going on to NT distributions. Shoub's work
-Krucker et al., commentary on this flare (from the Jul. 23 AR) and how to
 interpret its properties
-Hudson: why fuzzy? Broader contribution functions
-White: no cooling catastrophe
-Hudson: higher beta? Hmmm
-Cargill: cospatiality is ambiguous
-Hudson: what did Aschwanden and Alexander learn that Neupert didn't know 
 in 1967? haha
-Cargill: will CDS point at flares? EIS will solve the flare problem within
 90 days
-Cargill, Hudson, White: why is the evaporative flow so slow?  1D radiative 
 hydro relevance?
-Hudson: watch out for CS temperature claims in UVCS data
-White: non-thermal Nobeyama source under the FeXXIV source in April 21
-Hudson: note the dimming
-Krucker: early coronal souorces are common in the RHESSI data
-Vlahos: do the HXR and UV agree in the footpoints? Yes
-Vlahos: complexity revealed by the focusing of energy into small regions
-Sui: why is the blob appearance so non-uniform? No reason for reconnection 
 to happen uniformly
-Cargill: early Innes observations of CME flows in SUMER lines
-Sui: Khan paper published? Soon, soon
-Vlahos, Sui, et al: discussion of physical nature of WL prominence source

Veronig I: coronal thick target

-Vlahos, Fletcher, White, Krucker, Hudson: discussion of pre-impulsive coronal
 source
-Fletcher: is the early source larger? Maybe
-Hudson: are other wavelengths consistent with the density needed? There is a
 faint FeXXIV source there
-Sui, White: will discuss radio source
-Masuda: Imaging spectroscopy in early phase? Krucker will try again
-White: Will discuss radio emission
-Vlahos: Need to convert the whole magnetic energy of the loop
-Vlahos: Mix the accelerator and the target and change the paradigm and 
 perhaps get more reasonable energetics
-Hudson, Cargill: What about the real density and the filling factor
-Krucker: should see a simple thick target in the integrated spectra. But
 in early July 23 already see a break, so it is more complicated

Veronig II: collapsing trap

-Vlahos: need a more complete analysis than Bogachev-Somov (2005) show. Is
 there a more complete simulation?
-Fletcher, Vlahos, Cargill: discussion of the models, nothing is complete
 enough yet
-Sui: Can these coronal thick-target models replace the shock picture?
-Fletcher: must look at Feldman et al. (2004)

White

-Many: Discussion of nature of April 18 event. What part of the CME are we
 seeing. Sorry for the lack of notes, it took my full attention!
-Hudson, Fletcher: Assumptions of electron rate/density conversion
-Cargill, Hudson, Vlahos, Fletcher: Questioning Markus's schematic
-Vlahos: Single-particle approximation here. Not relevant?
-Cargill, Fletcher: Where is the convergence?
-Hudson: Second BIMA peak as collapsing trap? Maybe OK
-Sui, Krucker, Fletcher: Discussion
-Vlahos: Backwards in time sequence of footpoint brightenings
-Fletcher: What is the connectivity? There is no connectivity?
-Hudson: Is the microwave spectrum in the early phase of Nov. 3 2003 odd? No...
-Krucker, Hudson: The Apr 15 event requires a high-energy electron component
 not seen by RHESSI
-Vlahos: Nothing about the radio morphology suggests the standard cartoon, 
 just loops.
-Hudson: Sermon about pre-heating myth
-Vlahos; Initial footpoint brightening is really interesting
-Veronig: Downward motion in RHESSI? No.
-Vlahos: Mostly these radio events had CMEs? Yes
