Four great space weather events observed by SOHO and WIND

The dataset is a supplemental material for the paper: Extreme Space Weather Events of the Past 30 Years: Analysis and Implications for Vigil’s L5 Observations. It consists of data from 4 most extreme space weather events that produced great geomagnetic storms on date: 2001-03-31 2003-10-30 2003-11-20 2004-11-08 The dataset spans a period of 10 days before and 10 days after the date when the most extreme Dst index value was reached. Images and in-situ measurements are from the following space-based instruments in the highest available cadency. SOHO / EIT - images in 195 filter (https://umbra.nascom.nasa.gov/eit/) SOHO / MDI - magnetograph images (http://soi.stanford.edu/) SOHO / LASCO C2 and C3 - coronagraphs images (https://lasco-www.nrl.navy.mil/) SOHO / CELIAS - proton speed and density measurements (http://www2.physik.uni-kiel.de/SOHO-CELIAS/) WIND / MFI - magnetic field measurements (https://wind.nasa.gov/mfi/) The data were obtained by the pipeline presented at https://github.com/space-lab-sk/vigil-like-data. They provide a limited vizualization of how the ESA Vigil mission, which is currently under development, would have seen the most extreme events that were ever captured.
