Hi Kevin and list, Magnitudes from rocket fuel burns are hard to estimate. Solid fuels produce more visible particles than liquid ones. The OAM stage uses hydrazine, so it is in the hard to see category. It depends on the sun-rocket-observer angle, the power of the rocket, the altitude and range. Shuttle engines are easy to see but this OAM is so much smaller. I'm sure it must be a binocular object.
