Previous solar eclipse studies have observed different propagation effects at VLF/LF frequencies (3-300 kHz) compared with those observed at HF (3-30 MHz) frequencies. These differences are primarily due to the much longer wavelengths at lower frequencies in concert with ionospheric D layer interactions. To better understand the unusual eclipse-induced effects at VLF/LF frequencies, we present EclipseMob, a crowdsourced collection effort that will use smart phones as simple VLF/LF software defined radio (SDR) receivers to record changes in propagation from known transmitters during the 2017 Total Solar Eclipse.
