(1) RHESSI HXR CORONAL SOURCES SURVEY PAPER (Led by Lyndsay) Participants: Christe, Dennis, Fletcher, Hudson, Ji, Krucker, McTiernan, Pick, Temmer, Vaananen, Veronig Purpose: Overview the characteristics of the coronal source types seen by RHESSI. If this is to be eligible for publication in a refereed journal then there must of course be original analysis in it, but hopefully we can go a long way with the insights that people already have through working on other events. Most recent review on this is Cliver '86. Responsibilities: Oversight - Lyndsay First draft - Hugh 1. pre-impulsive phase hard spectrum (Sam and Ed and Haisheng) 2. pre-impulsive phase super-hot thermal (Sam and Ed and Haisheng) 3. above the (SXR) looptop impulsive phase source (Jim) 4. coronal thick targets (Astrid, Manuela, Laura) 5. long duration, hard spectrum (Hugh, Brian) 6. Type III stuff (Steven, Sam, Monique) I think that this paper should be a fairly observational paper, not too much theoretical discussion. Each numbered category corresponds to a different section in the paper. Section authors (in brackets) should aim to find 2 or 3 examples of each type, characterise their behaviour (especially in so far as what RHESSI tells us) and describe what is new, what is exciting, and what requires theoretical explanation. Hugh has software to identify limb-occulted events which may be useful when making a source selection. Extra co-workers can be added as needed. (2) RHESSI FLARE ENERGETICS PAPER (Led by Brian) Participants: Dennis, Gopalswamy, Share, Holman, Gallagher, Bone, Fletcher, Hudson, McTiernan, Purpose: Flare energetics, as far as can be determined from RHESSI, CME and GOES SXR (maybe also TRACE, EIT, OVRA, SORCE, but this might be another research project)from the October/November 2003 series of flares. This will involve significant new analysis and can therefore be sumbitted as a regular journal paper. Responsibilities: Brian Dennis - lead + whip cracker Nat Gopalswamy - CME Energetics Gerry Share - Ions (where available) Gordon Holman - HXRs Peter Gallagher - EIT/TRACE/OVRA Laura Bone - OVRA Lyndsay Fletcher - TRACE Hugh Hudson - TRACE WL Jim McTiernan - SXI Brian provides list of events for study (ie those with CME energetics from Nat) to other participants (in his PPT presentation). Others check for suitable data. RHESSI, SXI, EIT and GOES should be the core instruments, other instruments used on subsets of flares as appropriate. However, there is potentially a lot of data in total so need to guard against the paper getting too big and dragging on too long! (3) PRE-IMPULSIVE PHASE SOURCES - led by Ed Participants: Ed Schmahl, Monique Pick, Hugh Hudson, Astrid Veronig, Haisheng Ji, Lin Sui Purpose: Study build-up of energy in pre-impulsive phase (ie variation in number of electrons in pre-flare phase, or variation of energy spectrum). This will involve significant new analysis and will therefore be a regular journal paper. Responsibilities: First draft - Ed Lin Sui has pre-flare event list Jim McTiernan can also generate pre impulsive phase event list - and also select suitable candidates on basis of spectroscopy and images - pass list to Ed and Hugh for filter level II (for interesting events) - passed to Monique/Astrid/Haisheng to look for interesting data (4) RHESSI FOOTPOINT MOTIONS SURVEY PAPER Participants: Lyndsay, Sam, Lin, Paolo, Manuela, Haisheng (Tom Metcalf, Linhui Sui, Martin Fivian - all not present but we should involve them where necessary) Purpose : describe the characteristics of footpoint motion of sources seen by RHESSI (speeds, intensities, spectral behaviour), making distinctions between different 'types' of footpoint motion, and attempting to relate these to magnetic field configurations and draw overall conclusions about the progress of coronal reconnection. Again, this will utilise work that people have already done, but needs new analysis to make it into a regular journal paper. Responsibilities: Lyndsay - lead + first draft All - analyse and characterise footpoint movement with respect to neutral line, in following categories: parallel and in same direction, parallel and in opposite directions, perpendicular, random (others). Correlation with flux, spectral index Lyndsay and Manuela - look at constraints on foot-point motions from magnetic structures - reporting observations Lyndsay and Tom Metcalf - discuss constraints on coronal structures from footpoint behaviour (5) MULTI-WAVELENGTH FLARE DEM (led by Ken Phillips, Brian Dennis) Participants: Brian Dennis, Ken Phillips, Jim McTiernan, LiWei Lin, Amir Caspi, Mikko Vaananen Purpose: Produce a flare DEM as a function of time (preferably for a few flares). This is an original research project, so can be submitted as a regular journal paper Responsibilities: Ken - first draft Peter - identifying events/CDS/CHIANTI DEM Jim - pixons LiWei Lin - pint-of-ale (MCMC) Amir - iron line complex Mikko - XSM Peter - Identify events on basis of CDS/RHESSI data and circulate Mikko - Check for XSM events Peter, Amir, Mikko - calculate fluxes and instrument stuff and give to Jim and LiWei and Peter who will do DEM calculation, with different techniques Brian - decides how big sigma is
