Rodriguez: /* Selected campaign events */

Campaign Event Group led by Nariaki Nitta (USA), Luciano Rodriguez (Belgium); At-large leaders: David Webb (USA)

==Objectives==

*Provide textbook-style standard CME-ICME chain events from the Sun to the Earth based on the state-of-the-art observations and successful theoretical analysis and numerical simulation: happy stories

*Examine controversial Earth-Affecting CME/ICME pairs during the STEREO era (from 2007): surprising stories

*To analyse the complications that arise when linking CMEs to ICMEs

*To obtain new insights that could be applied when forecasting ICME arrivals at the Earth

*Integrate theory, simulations and observations in order to get a complete view of the chain of events from the Sun to the Earth

==Scientific Questions, Technique Approach/Methodology==

===What are the common issues when linking ICMEs to CMEs?===

*Multiple events

*Stealth CMEs

*CME deflection

*etc.

===Calculating arrival times===

*Projected vs 3D speeds

*Propagation models (DBM, ENLIL, etc.)

*Error margins

===When/why will a full halo CME not arrive to the Earth?===

===When/why will a narrow CME (as seen from L1) arrive to the Earth?===

===What solar parameters can we use to provide an estimation of geoeffectivity?===

===More interesting topics:===
*Forbush decreases (Mateja, Dragan, Darije)
*Sympathetic flares (Nariaki)
*SEPs (Bernd?)
*Prominence material in ICMEs, signatures in compositional data (Luciano)
*Determination of S/C path through the ICME, central or flank crossings
*Use of remote data to infer Bz: magnetograms, extrapolations, flux rope orientation
*False alarms: CMEs that did not arrive to the Earth when they were expected to, and viceversa.

Rodriguez:

Campaign Event Group led by Nariaki Nitta (USA), Luciano Rodriguez (Belgium); At-large leaders: David Webb (USA)

==Objectives==

*Provide textbook-style standard CME-ICME chain events from the Sun to the Earth based on the state-of-the-art observations and successful theoretical analysis and numerical simulation: happy stories

*Examine controversial Earth-Affecting CME/ICME pairs during the STEREO era (from 2007): surprising stories

*To analyse the complications that arise when linking CMEs to ICMEs

*To obtain new insights that could be applied when forecasting ICME arrivals at the Earth

*Integrate theory, simulations and observations in order to get a complete view of the chain of events from the Sun to the Earth

==Scientific Questions, Technique Approach/Methodology==

===What are the common issues when linking ICMEs to CMEs?===

*Multiple events

*Stealth CMEs

*CME deflection

*etc.

===Calculating arrival times===

*Projected vs 3D speeds

*Propagation models (DBM, ENLIL, etc.)

*Error margins

===When/why will a full halo CME not arrive to the Earth?===

===When/why will a narrow CME (as seen from L1) arrive to the Earth?===

===What solar parameters can we use to provide an estimation of geoeffectivity?===

===More interesting topics:===
*Forbush decreases (Mateja, Dragan, Darije)
*Sympathetic flares (Nariaki)
*SEPs (Bernd?)
*Prominence material in ICMEs, signatures in compositional data (Luciano)
*Determination of S/C path through the ICME, central or flank crossings
*Use of remote data to infer Bz: magnetograms, extrapolations, flux rope orientation
*False alarms: CMEs that did not arrive to the Earth when they were expected to, and viceversa.
