NASA Eclipse Explorer: An interactive guide to the 2017, 2023, and 2024 Solar Eclipses

The NASA Eclipse Explorer is an interactive web application that allows users to visualize different aspects of the three recent solar eclipses in North America: August 21, 2017; October 14th, 2023; and April 8th, 2024.


A control menu appears on the left with buttons to toggle individual elements on the map, simulate the position of the eclipse shadow over the course of the eclipse as a function of time, and jump to pre-selected bookmarked cities.


Clicking a city label will open a pop-up that shows the current weather, a countdown to (or from) the eclipse, information about the percent coverage or duration of totality, and buttons to automatically skip to different phases of the eclipse as viewed from that location. Additionally, a simulation of the view of the Sun and Moon from that location with up-to-date NASA Solar Dynamics Observatory (SDO) imagery is shown on the left of the pop-up box. 


In locations where there is totality, and during the phase of totality, the simulated image will show the corona of the sun for that eclipse. For the 2024 Eclipse, Predictive Sciences Inc. has developed a continuously updating "Live Prediction" model of the solar corona based on data from SDO, which is providing roughly hourly updates to the corona image until April 8th.
