Motion of a Coronal Mass Ejection by Christian J. Mercado

Project:     NASA Heliophysics Teacher-Developed Lessons

In this lesson, students will learn about coronal mass ejection (CME) processes that take place in the Sun. An important part of space weather research is to measure the velocity of CME and their acceleration as they leave the Sun. This is done by tracing features in the CME and measuring their positions at different times. Students will see this process using simulators and calculate the velocity and acceleration of a coronal mass ejection (or CME) based on its position in a series of images from the LASCO instrument on SOHO.
