Monthly WS1 proficiency passes will resume. The WS1 passes had been put on hold during TDRS-K interference testing. There are no extremely contentious periods (e.g. GRAIL launch Sep 2011) currently in the DSN schedule. There had been some concern about the LADEE launch in Sep 2013. But there are only a few days in September with minimal DSN support. Depending on the WS1 schedule, additional passes may be scheduled. A WS1 pass was taken on Monday 6/24/2013 (DOY 175 1430-1630z). High-rate Eb/N0 was 1.8 dB. No problems encountered. ======================================================================== Anomalies: None
