What it actually is, is a binary system where one of the stars has started to eject its envelopes at the end of its life, while the other still circles it, leaving a spiral trail in the outflowing gas. The regular gaps between the trails correspond to the 800-year orbital period of the binary.

Being short on actual content, this week I bring you an announcement of some long-postponed site updates. I updated:

- The Fanfiction page, with content ratings
- Such stories that have the MA rating, with content descriptors/warnings.
