Title

On the morning of 2025 April 22UT C/2025 F2 had brightened a little to magnitude G=9.3/G=9.6 as calculated from a couple different sets of data in an aperture diameter of 3'. What is interesting is that there appears to be clumps or fragments in the images from these calculations, which may account for the comet brightening. These images were collected at an altitude of 5 degrees under nice clear morning skies just as twilight was approaching.
