Mastodon has a bug with aspect ratios of images interfering with adding alt text, so I couldn't add alt text.
Here it is:
Three stages of the annular solar eclipse over Roswell, New Mexico on October 14, 2023.
The first image shows a quarter-covered sun. Some solar spots are visible.
The second image shows a mostly covered sun.
The third image shows the annularity "ring of fire".
