So, mostly clockwise-in, as is the case in this image. But note the counterclockwise-in coil on the far right side of the image. “174 spirals have a clockwise-in orientation, 43 are counterclockwise-in, and 52 circular features remain unclassified due to limits in resolution.” – from the manuscript in Science.
