The NOCC workstation has been down for the last two occultations, so we have no values for the SNT, and we cannot see the SSI display. For this occultation, DSS 45 had BOT at 21:45 which was within the ingress record period. I suspect that they were on point early as usual. The ingress measurements from occultation #144 and later will probably not be of scientific value because the spacecraft will go off-Earth point before ingress can be seen. The data will be used to improvee our statistics regarding DSP sawtooth errors and remote operations. Ingress: Record Times: 109-21:42:00 to 109-21:59:00 One-way Times: 109-21:42:05 to 108-21:58:24 Expected Surface Begin: 109-21:53:16 Start of slew off-Earth (ISH): 109-21:52:25 SNT: not available SPK: spk_i_980417_OD245_274_V1 SOE: p247b.03.soe Script: 98108.15.a247.scr Last attenuation change at 21:47:00.
