Note: Comet imaged using filter from 500nm to 1100nm wavelength (so C2 is expected). Here applied “Sobel contour filter” to analyses comet nucleus (and probably it went into four fragments, may be wrong too..:)). We do not find LS operation correct due to nucleus disintegration and more optical centers. Cheers!
