Details:
This is comet C/2025 K1 (ATLAS) which wasn't suppose to survive Oct 8 perihelion due to it's low intrinsic brightness. It did survive and even more peculiar is its chemical composition lacking in carbon compounds(CN, CO, CO2 and C2 compounds lend to blue green cometary coloration). This 8 -9th magnitude comet has a higher ratio of OH and H2O compounds leading to a red/brown/golden color rarely seen in comets. A morning comet, still fairly impressive.
