Details:
On the evening of 2025 April 29 Comet C/2025 F2 (SWAN) had a 9' (0.15 degree) long tail at a position angle of 349 degrees from where the comet coma use to be before the comet disintegrated. On the evening of 2025 May 2 the tail was not evident beyond the disintegrated debris field in the 4.8' (0.08 degree) wide aperture diameter circle, at least not in the 50mm f/5 Refractor and IMX462 camera. Using the 4.8' wide aperture diameter circle to encompass the major part of the disintegrated comets debris field the comet remnants magnitude was 8.5 on April 29 and 8.6 on May 2. There were no stars brighter than magnitude 15 in either 4.8' wide aperture diameter circle and the faintest stars in all images was about magnitude 14. The images were taken at an altitude of 4 to 5 degrees just as twilight was fading and before the comet remnants sank into the atmospheric haze.
