How it works:
This chart takes data from different satellites and propagates them into a chart. Aurora Admin then calculates the nearest position of the space craft and calculates the time to Earth for the current space weather conditions. We add this time to Earth to the current time to calculate the exact time of arrival.
This chart has an accuracy of an estimated +/- 15 minutes.
