Normalised intensities received by all core stations at an observing frequency of 44.13 MHz, plotted on a geographical map of the stations. The intensities are colour-coded using a colour scale from yellow to purple with a range of 0.8–1.3 respectively. Times are at ~10 s intervals from 21:22:25 UT at top left to 21:24:15 UT at bottom right, and each plot uses data samples with an integration time of 0.92 s. Plot diameter is ~4.5 km.
