[52.02] Magnetic Source of 16 Mar 2009 Filament Eruption: An Imagined VSO Study

M.J. Penn (NSO)

There have been many studies of the famously geo-effective CME of 16 Mar 2009 and the associated filament eruption. The general features of the current model, where global sub-surface flows transport magnetic fields which weaken the overlying magnetic arcade and allow a tiny intra-network dipole to trigger the eruption, are mentioned. Particular emphasis is placed on the performance of the Virtual Solar Observatory with respect to this event. The multi-wavelength and multiple spatial scale nature of the VSO-retrieved data is shown to be essential to several studies of the filament, flare and CME. A movie-based VSO user interface facilitated data retrieval. Raw data access was critical in several cases, and pointers to the relevant calibration data were very helpful. The ability to retrieve magnetic extrapolation models from the VSO system aided in several studies of the filament eruption trajectory, as did the available in-situ data. Finally, the meshing of the public data with the open-PI data from several observatories was helpful, though improvements are suggested.
