This Tidy Tuesday exercise explores data from NASA’s Scientific Visualization Studio about the annular solar eclipse paths recorded on October 14, 2023 and April 8, 2024.

eclipse_annular_2023.csv and eclipse_total_2024.csv can be found in the data subfolder of the tidytuesday-exercise folder. The datasets containing path information of partial_ eclipses are too large to be saved to github - c’est la vie.

Explore Eclipse Path Datasets

The two datasets contain information about the path of the moon across the sun at different locations within the United States during either the annular solar eclipse of 2023 (eclipse_annular_2023.csv) or the total solar eclipse of 2024 (eclipse_total_2024.csv.) An annular eclipse occurs when the moon is closer to its maximum distance from the Earth in its orbit and, as a result, a ring of sunlight is still visible around the moon’s shadow when they are perfectly centered in the sky. This is not the case for a total eclipse, where the moon is close enough to the earth that the sun is completely obscured. The difference is pretty stark, and can be seen in the image below:
