Thanks for that link Robin. It looks as though the offset of the Sodium tail is just 3 degrees from that of the main dust tail in the PSI image. Presuming that this image shows south at the top, the Sodium image is offset in a clockwise direction. I have measured Andy’s image and it shows that the red tail is offset approx 17 degrees in an anti-clockwise direction. So I don’t think the red tail is Sodium.
