Russell,

I had initially designated the OneWeb launch as 2021-060 in the SupTLEs, based upon actual launches. However, when we started receiving the 18 SPCS TLEs, they showed 2021-061. Neither Jonathan nor I can account for any missed launch that would support the difference, but the 18 SPCS SATCAT is incomplete at this point. I would expect there will be some adjustment soon, but it may not occur until after the end of the US holiday on Tuesday.  - TS
