That's the dust ejecta from a crater about _1 to 5 meters_ deep - which
is not alot of volume - spreadout over a 100-120km horizontal radius.
That will not be visual because it will be hidden in the dark limb. It
will be visual depending on how much of that ejecta cloud goes
vertical and peeks above the dark limb into the sunlight. How much of
that will occur, I don't know. But it's certainly worth a 5 minute
peak with binos or a scope, with the expectation that you probably
won't see anything.
So long to Smart-1. It's been a great satellite. Looking forward to
the ESA processing and releasing all the photos.
I hope Venus Express, which I understand has just completed its orbit
breaking manevuers, will be as successful.
