Details:
After its first approach to Earth, I imaged comet C/2025 K1 (ATLAS) on August 21, 2025, when it was near the star 9 Herculis. In this image it shines at about magnitude 12.5, showing a greenish coma just over 2 arcminutes wide with moderate central condensation. The tail extends roughly 20 arcminutes.
On its way to perihelion, which it will reach on October 8 at only 0.33 AU from the Sun —inside Mercury’s orbit—, the comet faces a high risk of disintegration. If it survives, it could become observable again on its return toward Earth, in the morning sky of the Northern Hemisphere, reaching a brightness near magnitude 8 and perhaps visible with binoculars.
Takahashi FSQ106 f/5, Moravian C3-61000. LRGB=18min., FOV=117x66'(crop), N:Up E:Left.
