Hello,
I don't think the spot is visible anymore. We've observed it about a month ago and it was clearly visible in a 20 cm newton and 28 cm SCT. A friend of mine, that has very good eyes, also saw it in 15 cm refractor.
When I watched yesterday and a day before yesterday I just couldn't see it, even after 15 minutes of observation. It is also true that I only watched through a 12.7 cm refractor. The impact is also much closer to the pole, than moon shadow transits, which mostly occur in the equatorial zones
