TWINS Geomagnetic Storm Catalog

ICME Storms

CIR Storms

Unclassified Storms

The TWINS Storm Catalog presents data, analysis and simulation results for geomagnetic storms with minimum SYMH < -100 nT and other storms of interest.  For each storm period listed above, TWINS 1 and/or 2 ENA images together with maps of equatorial ion flux and pitch angle anisotropy along with pitch angle distributions and energy spectra at the location of the peak flux deconvolved from the ENA images and simulated using the CIMI model are presented each hour of the day.  ENA images and both deconvolved and simulated results at more frequent times are available.  Pitch angle distributions and energy spectra are also available at other equatorial positions.  For more information contact
