Comet C/2025 Swan R2
in the evening sunset sky
10/2/25

 

            
Just now emerging
            from the sunset twilight sky, this new comet has been heavily
            imaged from the southern hemisphere, and is now heading northward
            to make its showing in our skies. Just 5.5 magnitude, it is difficult
            to get a clear shot so immersed in the bright sunset sky, but
            here I was able to get 13 good frames with the comet about 5-10
            degrees up in the south west. Hoping it will be better in a week
            when It passes Earth and gains about half a magnitude.
