2025f2 20250416 1142 molason

Using the same equipment and setup as yesterday morning, my stuff could not see any sign of the long tail of Comet C/2025 F2 (SWAN) observed yesterday morning although I am sure that it must be there, just a lot fainter. On the morning of 2025 April 16 C/2025 F2 had faded some from yesterday morning with a magnitude 9.6 as calculated from 6x20s images thru a green filter in an aperture diameter of 3.5'. I don't think the Moon made any difference since it was about the same illumination as yesterday morning and in the southwest sky. Both mornings the sky appeared perfectly clear.
