Comet A6 Lemmon and R2 Swan Different Days, Different Telescopes, and Different Locations

I have made observations of C/2025 A6 (Lemmon) and C/2025 R2 (Swan) from Columbia, MO with my Seestar S30, Dwarf 3, Unistellar Equinox 2, Celestron Origin, and my Astrophotography Rig on different days. Also, I have a Seestar S50 located at Starfront Observatories in Rockwood, TX which I control remotely. The observations in Columbia, MO were made at my home which has a bortle 7 sky (due to the proximity of a large light source across the street) and I abbreviate this location by COMO. The Starfront Observatories has a bortle 1 sky and I abbreviate it as SFRO. It is interesting to note how the comets change based on day of observation, the telescope that is used and location of the telescope.


I began observing A6 Lemmon on 10/2/2025 when it was visible in the morning sky during the first half of October. It then became visible in the evening sky after sunset after mid October. Comet R2 Swan has been visible in the evening sky from late September 2025.
