In this gif animation of C/2021 A1 (Leonard) the comet is magnitude 7.2 and 57 million miles from Earth. The gif shows the comet coma overexposed in an attempt to show the fine detail of the tail near the tear drop shape of the coma. The tail extends well beyond the field of view of this gif. The gif animation is composed of 25 images each 60 seconds long, showing 27 minutes in the life of the comet. The field of view of the gif animation is about 0.3 by 0.3 degrees. Due to memory size limitations the gif has been resized a little smaller than the original image.
