The interaction arises at different stages from the solar surface, between segments of a filament, to the interplanetary medium, appearing as ejecta or multiple-magnetic clouds (MultiMCs).

The seven events were triggered by interplanetary signatures, which arise as a consequence of interaction among different solar ejections. Welcome to WDC for Geomagnetism, Kyoto Dst index service Three versions of AE/Dst indices Real-time (Quicklook) Dst index Provisional Dst index 2017 - 2020 Final Dst index 1957 - 2016 Dst and AE (Hourly Values) indices Plot and data download are available except for real-time AE index. 3 Results: IMF B y Effect in CIMI Fluxes and Energy Content Figures 1a and 1b show the omnidirectional fluxes of 56 keV protons for the last timestep (8.00 hr) of the two runs at the geomagnetic equatorial plane (minimum B field plane.

At least one full halo CME with a speed on the plane of sky above 900 km/s participates in every studied event. To quantify the intensity of the ring current we use the Dst index downloaded from NASA GSFC's OmniWeb server. These events are expected to be better related to geomagnetic induced current (GIC) events than those events where any geomagnetic index is far from its quiet time value. As additional features, we include calendar year, day of year, and hour of day signals. On these for- mats, several retrieval and visualisation tools have been built, such as OMNIWeb, CDAWeb, PAPCO, SDDAS. We present the results of an investigation from the Sun to the Earth of the sequence of events that caused major Dst decreases (Δ Dst≤ –100 nT during 1 h) that occurred during 1996–2005. This data is curated by NASA’s Space Physics Data Facility and is available through the OMNIWeb database1. correlation between Dst and VBs for magnetic cloud and complex ejecta were 0.77 and 0.71, respectively.
