History of EclipseMob

The effect of the Solar Eclipse was first collected by William Henry Eccles on April 17, 1912 using a transmitter of approximately 54.545kHz frequency and a wavelength of 5,500 meters. It was collected later for the same eclipse in France and Denmark using the transmitter at the Eiffel Tower, Paris. The transmitter had a frequency of 115kHz. EclipseMob aims to solve the problem highlighted in these first studies.


The EclipseMob Project and why we care?

The crowdsourcing effort, EclipseMob, is collecting two radio wave signals from the Solar Eclipse that will be occurring on August 21st, 2017. One of these signals will be transmitted from the WWVB radio station in Colorado and one from the Navy transmitter in central California to study the effect of sunlight on the ionosphere. Why crowdsourcing? Crowdsourcing allows us to collect radio wave signals at locations all over the United States so we can study how the signals are affected as they travel along different paths. Disturbances in the ionosphere can cause further issues with communication around the globe. This can cause possible disruption to GPS signals and emergency communications that utilize the ionosphere when cell towers are down during instances such as hurricanes or other natural disasters.
