VLF sub-Ionospheric Data for the December 26, 2019 Solar Eclipse Observed Using Multi-stations VLF Radio Network in India

The VLF data attached here contain the low-latitude D-region (60-90 km) ionospheric disturbances due to the December 2019 annular solar eclipse observed using the multi-stations Very Low
Frequency (VLF) radio network in West Bengal, India. VLF signals from communication transmitters were received from ten places using low-cost VLF radio receivers. The receivers were capable of recording the amplitudes of VLF signals mainly from the transmitters VTX, India at 18.2 kHz and NWC, Australia at 19.8 kHz. This file also contains standard reference signal obtained by averaging quiet day data
around the solar eclipse day of December 26, 2019. The data was prepared by the Near-Earth Space and Atmospheric Observatory (NESAO), Kolkata, India. The first column is the time in UT (Hour) and the second column is the VLF amplitude data.
