ocr: LASCO To answer these questions (on the previous page), the LASCO investigation will study the transport of mass, momentum, and energy through the corona and into the solar wind, by measuring: Global distributions of key plasma parameters: temperature, density, bulk and nonthermal (turbulent) velocities, and direction of the magnetic field Time sequences of coronal dynamical events, especially processes that occur in coronal mass ejections, and the conditions that trigger them The spatial distribution and properties of circumsolar dust particles, including those newly released from sungrazing ...
