Space weather situation in March 2015 is shown using the daily averaged time series of Kp and F10.7 indices. While Kp index is unitless, F10.7 has the unit of solar flux units (SFU) with \(1 \ SFU = 10^{-22}W m^{-2} Hz^{-1}\). The values corresponding to the time window in Table 1 correspond to day of year (DOY) 71, 72 and 73 of year 2015. Data for Kp and F10.7 are downloaded from NASA omniweb explorer portal https://omniweb.gsfc.nasa.gov/form/dx1.html accessed on 26 June 2022
