At AOS with station 24 from 1622-1625, we were not getting TLM data. It was definitely a ground problem according to our DSS-24, and we are told by them that there was no loss of recorded data. Herman Marshall was in to ask about the upcoming 3C273 simultaneous observation. It needs to be scheduled at ~0800 Jan 9th to get SAX and other coverage. we spoke with Anil, who promised to look into it and call Herman.
