Earth directed ICME Catalogue

The Wind mission, operating during the last two decades, monitors in-situ observations critical to identify large scale solar transient events at 1 AU.

Interplanetary coronal mass ejections (ICMEs) are defined by the net effects that a CMEs displays in the interplanetary medium, detected by in situ instrumentation, with specific imprints in the observations. This catalogue provides the compiled list of ICME events with an embedded magnetic obstacle (MO) observed by Wind over more than 20 years. A MO is defined as the interval within an ICME where the magnetic pressure dominates over the plasma pressure concurrent with a rotation in the magnetic field direction.

The information has been catalogued by year with the following ICME in situ parameters:

  • Start ICME time: defined by the IP forward shock (Y) or sheath signatures (--)
  • End ICME time: defined by the end of the MO
  • Magnetic obstacle (MO) start/end times
  • MO characteristics:
    • Flux-Rope (F-/Fr/F+): Magnetic field changes monotonically with organized signatures of magnetic structure
      • (F-) Small field rotation
      • (Fr) Magnetic field rotation between 90 and 180 degrees
      • (F+) Large field rotation
    • Ejecta (E): Magnetic field changes monotonically without clear pattern of changes
    • Complex (Cx): Indications of more than one magnetic field rotation
  • In situ data plots
    • Magnetic field (MFI)
    • Plasma parameters (SWE)
  • Heliospheric overview using the current solar, heliospheric, and magnetospheric observatories
