I'm not sure that even NASA saw much of a plume visually. I watched with an 8" Schmidt-Cassegrain (at 8:31 am my time), and I didn't see anything.
My little girl woke me up at 5:00 am to go pee. After taking her to the bathroom and getting her back to sleep, I carried my gear down two flights of stairs and locked it in our car (parked on the street) to cool down. At 7:30, the sky was almost completely cloudy. Started to clear at about 8:00, so I went out and set everything up. Still clear at 8:31 and the Moon was high in the sky. The seeing was fairly steady, and I had a clear view of the area at my highest magnification, 254x. Saw nothing, but I'm not a great observer, and, by 8:31, the features were somewhat washed out by daylight.
