Introduction

This document contains a number of visualizations pertaining to a major ionospheric storm event that occurred in November 1993. We present YOHKOH Soft X-ray data that shows possible solar influence in the event that was observed and subsequently modeled using the AMIE procedure. The procedure is used to generate a series of animations showing correlations between the observations and the computed parameters. This page also contains a list of related URLs.

The storm event timeline contains details on the IMF, satellite location, Magnetosphere, inner plasmasphere and the ionosphere during the storm period.

The Solar Influence - YOHKOH Soft X-ray Observations

Soft X-ray data from the YOHKOH SXT were used to generate an animation (722Kb Mpeg, 3.4Mb Quicktime) covering the period October 29 through November 1, 1993. A potential CME source can be noted near the end of the animation sequence if you closely follow the bright regions in the lower left portion of the animation window. The bright vertical feature at the end of the animation is due to sensor saturation.
