It seems quite a few people saw it, both thanks to your tweet, but also by chance. I'm very glad I took the time to study the mission overview brochure. The cube sats that were deployed in a slightly different orbit compared to Landsat 9 increased the mission duration long enough to place the de-orbit burn and fuel dump over Europe, and fortunately at a time of day and time of year where a part of the track was in sunlight. Observing a fuel dump has been an item on my satellite tracking bucket list for quite a while, but Europe isn't that well placed with respect to the popular launch sites, so it's been a long wait. By chance I had my camera pointed in roughly the right direction to catch the fuel dump as it exited the shadow. This image shows the quite dramatic change in color as the sun rises as seen from the upper stage: https://twitter.com/cgbassa/status/1442615380359450626 That thread also shows one of the final images of the fuel cloud setting below the horizon.
