Subject: IBEX USHI01 Contacts DOY 149 and 150

Hi everyone,

The USHI01 DOY 149 15:00 UTC failed for Doppler (really the lack of Doppler). Can anyone confirm that the contact began on time? The first measurement file we received was at 15:23 and it was empty (presumably because we lost telemetry at 15:19 according to Sheral). I checked with Dan Hobel and he confirmed that no tracking files were created prior to 15:23. This isn't a huge deal since this was not a primary contact, but I am trying to understand what happened.

The USHI01 DOY 150 16:00 UTC pre-maneuver tracking contact provided good Doppler and was successful for FDG.

Thanks,
Marissa Intelisano
