A STEREO Survey of the Mass of Coronal Mass Ejections Observed at Earth in 2008-2012
Abstract
The total mass is a fundamental physical parameter of a coronal mass ejection (CME) that can be estimated from calibrated white-light images. Advances in measuring the location of CME trajectories in three-dimensional space from STEREO data have reduced the error in the mass estimate. We use STEREO observations from 2008 to mid-2012 to estimate the mass of CMEs also observed at Earth with WIND. These measurements are performed on data from each STEREO spacecraft separately, providing simultaneous measurements from different viewing angles. We use those events studied in Wood et al. 2017 to compare CME mass with other measured parameters. Additionally, we compare the mass estimates with the density measured in situ at Earth.
