PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 1999-05-26 NOTE = "MGS RST Instrument Health Report HEA9146A.TXT" END_OBJECT = TEXT END Miscellaneous ============= Users who retrieve MGS radio science data from our magellan.stanford.edu server are reminded that the Stanford group is changing buildings in about four weeks. The official move date is 23 June, but packing begins two days earlier and unpacking and recovery are likely to take a couple days after the move. Specific information on the move varies depending on the source; but we are expecting to be non-functional for from one day to a week. Trish Priest will watch for spacecraft and ground anomalies during our move; data collection and distribution will resume once we are re-established in the new building. All computers will retain their host names; Stanford machines (not the SOPC) will have new IP addresses.

The signal returns to expected strength 5-6 minutes later. Cause for this anomaly is not known. Signal in data beginning 1999/146-03:05:00 starts about 5 dB below normal levels and immediately drops to the noise level about 5 minutes later. A couple minutes later it has rebounded to about 3 dB above the noise level, then it disappears entirely. We have been expecting an impact on ingress occultations from gimbal limitations, but this event shows none of the sidelobes that would be expected if the spacecraft antenna moved off Earth point. This recording will not be useful for science analysis. The next seven occultations (after 1999/146-03:05:00) have not been found in Mgs_CDR_QueryServer.
