Hi David,

I think that V shape and the right hand wing (on your image) feature have been faintly visible on some unfiltered images since the summer.
Such as here:

and

Was it absent in your similarly exposed Rc filtered images from earlier in the year? The nebula is heavily reddened, so you might well see changes before those of us working unfiltered noticed them.

Do you still measure the nebulosity brightness at all? What does that curve say?

Would be nice for this or McNeil’s to reappear at last. Looked at Thomme’s last night and can’t see much change since I started looking at it and McNeil’s is absent with V1647 Orionis in the 19.5-20.5 mag range when skies are clear enough to detect it.

Happy Solstice!
