we were lucky enough to capture an intriguing phenomena: in our images is clearly visible a nice disconnection event (DE) in the plasma tail of the comet (evidenced by a red circle in this rendition). The DE indicates that the comet has recently passed through a disturbance in the magnetic field carried by the solar wind, that destroyed the original plasma tail, creating a new one. The separation of the two ion tails indentified by the DE, is visible in our image as a kind of elongated and diffuse "knot" along the plasma tail
