Contents
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: a happy story
- Examine controversial Earth-Affecting CME/ICME pairs during the STEREO era (from 2007)
- 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
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?
