“…As shown in Figure 5, the time delay of the phase peak of LF transmitter signals after totality was 2–10 min. Previous studies also showed a similar time delay of 4–7 min [ Sen Gupta et al , 1980; Lynn , 1981; Mendes Da Costa et al , 1995]. We speculated that the following two factors might have caused the time delay: the electron production rate of the partial solar eclipse after totality and the electron loss rate by recombination.…”

“…[ Dixit and Rao , 1980; Chandra et al , 2007]. Also, the influence of eclipses on the low‐latitude D‐region (i.e., over the equatorial anomaly region) is much less studied during ionospheric sunrise transition period [ Mechtly et al , 1969; Patel et al , 1986; Mendes da Costa et al , 1995; Clilverd et al , 2001]. A solar eclipse is similar to the onset of a short‐time night; therefore, the accompanying effects in both cases are normally expected to be similar.…”

“…It was called as RFI when any disruption created from natural sources or man-made that affects it. There are past investigations reported by [6] and [7] found that two significance effects during a solar eclipse were signal frequency and path length. This RFI survey must be done for radio astronomical purposes in order to know the quality signal of the Sun.…”
