Details:
My 5 year old helped with these taken with an 80mm lens on a Nikon D7100. As soon as we stacked them he said "the comet is only green on one side". This led to a restack, and then a retake and restack. He was right. The dust tail appears to be emerging! He explained it to me thus "two carbon atoms, they stickeded together, then got excited and glowed green, while on the bottom sunlight is just reflecting off the dust atmosphere"
