Captured under favorable conditions with the Twin RASA 8 systems equipped with ZWO ASI2600MM Duo cameras.
Comet Lemmon has now entered the inner solar system, where solar radiation and the solar wind interact intensely with its ionized gases. This generates a magnificent ion tail rich in filaments and dynamic plasma waves, shaped by the solar magnetic field. The green coma mainly originates from diatomic carbon (C₂) emissions, while the bluish tail traces carbon monoxide ions (CO⁺).
As the comet approaches its perihelion on November 8 2025, the ion tail is expected to display strong brightness variations and turbulent structures, driven by solar activity and outgassing from the nucleus.
