I would like to share a comparison of images of comet C/2024 S1 (ATLAS) from October 20 and 22.
The comet's appearance changed dramatically between October 20 and 22, 2024. The images were captured using the FRAM robotic telescope (MPC I47) at the Pierre Auger Observatory in Argentina, 30cm ODK, f/6.8, and a Moravian Instruments CCD G4-16000 camera. Photometric measurements (in V and R filters) from these images are shown below.
C/2024 S1 (ATLAS):
2024 Oct. 20.36 UT: m1= 8.2 CCD-V, Dia.=2.2', 30.0-cm ODK reflector , Tail: 8.6 min. in p.a. 255 deg.
[Comet Alt.:10.4, Martin Mašek, FRAM telescope, near Malargüe, Argentina]

C/2024 S1 (ATLAS):
2024 Oct. 20.36 UT: m1= 9.0 CCD-R, Dia.=1.9', 30.0-cm ODK reflector , Tail: 11.7 min. in p.a. 254 deg.

C/2024 S1 (ATLAS):
2024 Oct. 22.36 UT: m1=10.1 CCD-V, Dia.=0.9', 30.0-cm ODK reflector , Tail: 3.2 min. in p.a. 253 deg.
[Comet Alt.:7.4, Martin Mašek, FRAM telescope, near Malargüe, Argentina]

C/2024 S1 (ATLAS):
2024 Oct. 22.36 UT: m1=10.7 CCD-R, Dia.=0.9', 30.0-cm ODK reflector .
[Comet Alt.:6.9, Martin Mašek, FRAM telescope, near Malargüe, Argentina]

Clear skies,
