The DSS 65 track ends 5 minutes after periapsis. We have requested that they continue to track 10 minutes longer -- until the end of their viewperiod. Needless to say, the station will be at low elevation angles. There is no station coverage immediately following the DSS 65 pass. -Trish ---------------------------------------------------------------------- From pmeshe@mail1.jpl.nasa.gov Wed Apr 8 11:53:53 1998 Received: from eis-msg-002.jpl.nasa.gov (eis-msg-002.jpl.nasa.gov [137.78.160.158]) by magellan.Stanford.EDU (8.8.5/8.8.3) with ESMTP id LAA09405; Wed, 8 Apr 1998 11:53:52 -0700 (PDT) Received: from [128.149.43.45] by eis-msg-002.jpl.nasa.gov (Netscape Mail Server v2.02) with ESMTP id AAA8005; Wed, 8 Apr 1998 11:53:33 -0700 Message-Id: Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" To: Asmar , Jen Caetta , Patricia Priest , Salvatore Abbate , hinson@nimbus.Stanford.EDU, rsimpson@magellan.stanford.edu, stoumpis@magellan.stanford.edu, joe@neptune.Stanford.EDU, len@nova.Stanford.EDU From: pmeshe@mail1.jpl.nasa.gov (Paula M Eshe) Subject: Occultation #123 Orbit #226 Date: Wed, 8 Apr 1998 11:53:33 -0700 Content-Length: 576 Status: R Hello Everything went well with Occultation # 123 at DSS 65.

Paula didn't get any POCA errors. Maybe this will help. Unless you get a sawtooth. Data Control can't find the ingress data, so I will do a retransmission tonight at the beginning of the DSS 54 pass. I will also open an ISA. I hope that the gravity data is looking better than the occultation data. We have suggested two more tests for SPC 60 to do in order to find the 6 dB. -Trish From joe@nova.Stanford.EDU Tue May 5 16:46:59 1998 Received: from nova.stanford.edu (nova.Stanford.EDU [36.10.0.123]) by magellan.Stanford.EDU (8.8.5/8.8.3) with ESMTP id QAA15883 for ; Tue, 5 May 1998 16:46:58 -0700 (PDT) Received: from neptune.Stanford.EDU (neptune.Stanford.EDU [36.10.0.149]) by nova.stanford.edu (8.8.8/8.8.4) with ESMTP id QAA23147; Tue, 5 May 1998 16:46:58 -0700 (PDT) Received: (from joe@localhost) by neptune.Stanford.EDU (8.8.5/8.8.3) id QAA06822; Tue, 5 May 1998 16:41:26 -0700 (PDT) Message-ID: X-Mailer: XFMail 1.2 [p0] on Solaris X-Priority: 3 (Normal) Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 8bit MIME-Version: 1.0 Resent-Date: Tue, 05 May 1998 16:21:12 -0700 (PDT) Resent-Message-Id: Resent-From: Joe Twicken Resent-To: Joe Twicken 723-3597 Date: Tue, 05 May 1998 16:41:26 -0700 (PDT) Sender: joe@neptune.Stanford.EDU From: Joe Twicken To: stoumpis@leland.stanford.edu, rsimpson@nova.Stanford.EDU, hinson@nova.Stanford.EDU Subject: RE: ODR Notice: /users/z15/procODR/81252312 Content-Length: 205 Status: R Egress ODR was not even processed to steering due to very low signal level.
