Editor’s Note: The HamSCI-related eclipse efforts comprise of a number of sub-projects. This article describes the EclipseMob project, which is an experiment led by a team at George Mason University and the University of Massachusetts at Boston. EclipseMob will study eclipse-driven ionospheric effects using the Very Low Frequency (VLF) and Low Frequency (LF) bands. Results of this experiment could aid in understanding propagation at the proposed 2,200 meter ham band.

Since 1912 there have been many efforts to collect and analyze data during a solar eclipse to help understand the ionosphere. These efforts have been conducted in frequencies ranging from VLF to VHF.  In most cases, individuals or small teams have collected data from disparate transmitters.
